The Lucky Penny did not glide into Void Junction so much as she limped, groaned, and threatened to throw a connecting rod through her own lead-lined belly.

Milo Vance stood with both boots planted wide on the vibrating iron deck of the cab, his left hand resting on the brass throttle lever and his right hovering over the emergency scram-wheel. Through the thick, leaded-glass windscreen, the station loomed out of the velvet dark like a wedding cake built by a lunatic steelworker. Void Junction was three miles of spinning Art Deco chrome, riveted girders, and glowing neon signage, all anchored at the dead-center Lagrange point between the inner worlds and the belt. From its gilded hub, twelve great magnetic rail-spokes radiated outward into the black, disappearing toward Mars, Venus, the Jovian moons, and points far uglier.

"Three hundred yards to the catch-fields, Skipper," Gus called out over the rhythmic chuff-hiss of the heavy-water condensers.

Gus was nineteen, built like a coal scuttle, and possessed the sort of unshakeable optimism that only came from never having seen a containment seal blow. He was currently leaning out the port-side cab window, his leather-gloved hand shielding his eyes against the harsh, sodium-vapor glare of the approach beacons.

"I can see the markers, Gus," Milo said, squinting at the brass pressure gauges trembling on the Bakelite dashboard. "Give me a quarter-turn on the boron dampers. If we hit the platform brakes with the core running this hot, we'll boil the station's containment field right off the pylons."

Gus ducked back in and hauled on the damper wheel. Deep in the bowels of the locomotive, beneath six inches of cast lead and three feet of bolted steel, the uranium pile gave a muffled, resentful hum. The needle on the temperature gauge reluctantly crept back out of the red.

Milo eased the throttle back, notch by notch. The Lucky Penny—officially registered with the Interplanetary Rail Authority as Locomotive 404, Class-C Freight and Passenger—was forty years old, which in atomic-rail years meant she was practically a museum piece. Her once-gleaming silver paint had been scorched to a dull, mottled pewter by solar flares and micrometeorite sleet. Her brass fittings were pitted, her cowcatcher was bent three degrees to port from an unfortunate encounter with a rogue ice-chunk near Ceres, and her left headlight flickered whenever Gus flushed the cab's chemical toilet.

Still, she kept time. Mostly.

Milo glanced up at the master chronometer bolted above the windscreen. Its luminescent green hands pointed to 04:17:52. Their scheduled arrival at Platform Zero was 04:18:00. Eight seconds to spare. That was close enough to keep the Stationmaster's clerks from docking his pay, though not quite close enough to earn him a free cup of coffee at the concourse automat.

The Lucky Penny crossed the threshold of the outer atmospheric membrane with a wet, rubbery thrum that made Milo's teeth ache. Instantly, the silent vacuum of the deep-space approach gave way to the roaring, pressurized din of Void Junction. The station's artificial air smelled, as it always did, of ozone, boiled cabbage, hot machine oil, and the faint, metallic tang of recycled breath.

Beneath the locomotive's massive iron wheels, the magnetic guide-rails caught hold. A shower of brilliant blue sparks erupted from the underside of the tender as the induction brakes bit down. The whole train—twelve battered boxcars loaded with Ganymedean ice-melons, mining drill bits, and three cages of remarkably quiet Martian rock-badgers—shuddered and compressed with a deafening chorus of clanking couplings.

Milo pulled the air-brake lever all the way back. The Lucky Penny gave one final, asthmatic wheeze of superheated steam, lurching forward another ten feet before her buffers kissed the hydraulic stops at the end of Platform Zero with a gentle, practiced clunk.

The chronometer clicked to 04:18:01.

"One second late," Gus sighed, wiping a smear of axle grease across his forehead with the back of his sleeve. "They're gonna hang us, Skipper. They're gonna march us right out to the airlock and feed us to the void."

"They don't hang you for one second, Gus," Milo said, reaching up to shut off the main dynamo. The cab lights dimmed, leaving them bathed in the eerie, comforting Cherenkov blue seeping through the sight-glass of the boiler. "For one second, they just make you fill out Form 12-B in triplicate. Now, go bleed the auxiliary tanks before the pressure builds up and blows the gaskets. I'm going to stretch my legs and see what the board says about our turnaround."

Milo grabbed his coat—a heavy, double-breasted woollen number lined with thin lead foil—and settled his peaked cap squarely over his graying hair. Pinning his dosimeter badge to his lapel, he unlatched the cab door and swung himself down the iron ladder onto the concrete of Platform Zero.

Platform Zero was not where the brochures were photographed.

If you bought a first-class ticket on the Venusian Zephyr or the Olympus Mons Express, you arrived at Platforms One through Four. Those platforms boasted polished terrazzo floors, potted plastic ferns, uniformed bellhops with gleaming brass luggage carts, and a grand, vaulted ceiling painted with murals of smiling, square-jawed pioneers conquering the solar system.

Platform Zero was tucked underneath the main concourse, right next to the station's primary sewage recyclers and the humming, windowless blockhouses that housed the central cooling towers. The ceiling here was low, crisscrossed with dripping condensation pipes and thick bundles of armored power cables. The lighting came from buzzing fluorescent tubes, half of which flickered at a frequency designed to induce a mild migraine.

Yet, for all its grime, Platform Zero had a certain stubborn dignity. It was the workingman's dock. It was where the milk runs, the ore haulers, and the rusty, patched-together local trains came to catch their breath.

Milo walked along the length of the Lucky Penny, his heavy boots ringing on the oil-stained concrete. He paused by the driving wheels to kick a coupling pin—purely out of habit—and squinted at the radiation badge on his chest. The little strip of film inside the plastic window was still a pale, healthy cream. No leaks today.

Ahead of him, the platform stretched toward a pair of swinging, wire-reinforced glass doors that led to the lower concourse. Scattered along the platform were a few dozen passengers waiting for the Io-Europa local, huddled on cast-iron benches with their cardboard suitcases and thermos flasks. A pair of station porters in faded blue coveralls were lazily pushing a hand-truck stacked with crates of vacuum-sealed spam.

Above the glass doors hung the Platform Zero departure board. It was a massive, soot-stained mechanical monolith, its face divided into rows of black split-flap slats that clicked and whirred whenever the central scheduling engine upstairs sent a pulse down the copper lines.

Milo checked his pocket watch against the big round clock mounted beside the board. 04:21. He had forty-five minutes to unload the rock-badgers, take on six tons of heavy water, and get his manifest stamped before the Lucky Penny was due to head back out toward the Belt.

He pushed through the swinging doors into the lower concourse, instantly greeted by the smell of scorched coffee and the rhythmic clack-clack-clack of a dozen teletype machines working behind a frosted-glass partition.

To his left sat the Platform Zero Automat, a wall of gleaming chrome doors and tiny glass windows displaying plates of gray roast beef, wedges of neon-yellow lemon meringue pie, and wax-paper-wrapped ham sandwiches. Milo fished two brass tokens from his trouser pocket, dropped them into the slot marked COFFEE – BLACK, and pulled the little chrome lever. A paper cup dropped into the recess, followed by a stream of scalding, tar-black liquid that tasted faintly of copper pipes.

"Morning, Milo," a raspy voice called out.

Milo turned, blowing steam off his cup. Leaning against the counter of the tiny newsstand across the aisle was Barnaby, a man who looked as though he had been assembled out of spare station parts sometime in the late thirties. He wore a green celluloid eyeshade, a plaid vest, and a perpetual expression of mild disappointment.

"Morning, Barnaby," Milo said, wandering over. "Anything new in the papers?"

"Same old," Barnaby grunted, gesturing with a rolled-up copy of The Martian Herald toward a stack of magazines. "Congress is arguing about the tariff on Jovian helium again. Some dame in New Chicago claims she saw a ghost on the Halley's Comet freighter. Oh, and the Stationmaster's got a bug up his tailpipe about the schedule. Again."

Milo took a cautious sip of his coffee. It was hot enough to strip paint, which meant it was perfect. "When doesn't he? The man's got a chronometer where his heart ought to be."

"Yeah, well, he's been down here twice this week already," Barnaby said, lowering his voice a fraction and leaning over the counter. "Brought his little clipboard and two of those boys from the Scheduling Office. The ones with the white coats and the slide rules. They were poking around the switchboards behind Track Zero."

Milo frowned. The Scheduling Office didn't send slide-rule boys down to Platform Zero unless someone had been cooking the fuel logs or smuggling untaxed moonshine in the water tenders. As far as Milo knew, the Lucky Penny was clean—mostly clean, anyway. He'd only carried three cases of unlicensed Ganymedean gin last month, and that had been for the Stationmaster's own brother-in-law.

"Maybe they're finally going to fix the gravity plating by the water tower," Milo said. "Every time I walk past it, my boots feel like they weigh eighty pounds."

"Sure," Barnaby said, looking unconvinced. "And maybe they're gonna paint the whole station gold and give us all pensions. You better check your manifest, Milo. The board's been acting funny all morning."

Before Milo could ask what he meant, a sudden, deep vibration rattled the floorboards beneath their feet. The glass jars of penny candy on Barnaby's counter clinked together. Above them, muffled by twenty feet of reinforced steel and concrete, came the unmistakable, earth-shaking roar of a Class-A express locomotive blasting through Platform One.

Even through the ceiling, Milo could hear the shriek of its electromagnetic turbines and the triumphant, three-tone brass horn that announced the arrival of the Venusian Zephyr. No doubt it was right on the dot, down to the millisecond, gleaming with fresh wax and carrying senators and movie stars who wouldn't know a boron damper from a butter churn.

"Show-offs," Milo muttered.

"They pay the bills," Barnaby said, shrugging. "Go get your stamp, Skipper. Don't want to keep the big clock waiting."

Milo finished his coffee in three heroic swallows, tossed the paper cup into a riveted steel bin marked INCINERATOR FEED, and walked down the concourse toward the Dispatcher's window.

The window was a small, arched opening barred with brass grille-work, behind which sat a young clerk with slicked-back hair, thick horn-rimmed glasses, and a green visor. The clerk was currently engrossed in feeding a long, perforated paper tape into a chattering brass reader.

Milo rapped his knuckles on the counter. "Morning, kid. Vance, Lucky Penny, Track Zero. Looking for my return clearance and a water-line chit."

The clerk didn't look up immediately. He waited until the paper tape finished its run with a sharp snick, tore it off, and then peered at Milo through the brass bars. His expression was entirely devoid of warmth.

"Train number?" the clerk asked, his voice flat.

"Four-oh-four. Line Fourteen. Ganymede-Io Milk Run."

The clerk turned to a tall, rotating rack of manila folders, spun it with one practiced finger, and pulled out a thick sheaf of papers clipped to a Bakelite board. He flipped through the pages, his brow furrowing slightly. He flipped back. Then he walked over to a pneumatic tube mounted on the wall, unscrewed a brass cylinder that had just arrived with a thump, and pulled out a slip of pale blue paper.

He read it. Then he looked up at Milo, and for the first time, there was a flicker of something in his eyes. It wasn't hostility. It was the polite, detached pity of a doctor looking at an X-ray he didn't want to explain.

"Wait here," the clerk said.

"Wait? I've got forty minutes to turn this kettle around, kid. I need my water chit."

The clerk didn't answer. He simply walked out of his booth, disappeared through a heavy steel door in the back, and left Milo standing alone at the brass grille.

Milo drummed his fingers on the counter. He looked back toward the swinging doors leading to Platform Zero. Through the wired glass, he could see the big split-flap departure board hanging above the tracks.

As he watched, the board gave a loud, mechanical clack-clack-clack-clack. The black slats spun in a blur of white lettering as the central scheduling engine upstairs updated the morning's roster.

Milo squinted through the glass, waiting for LINE 14 – GANYMEDE to flip into the BOARDING column.

The slats slowed. They clicked into place, one by one.

LINE 12 – CERES ORE... ON TIME. LINE 13 – EUROPA ICE... DELAYED 00:04.

And then, in the slot where LINE 14 had been just a moment before, the slats spun three times, hesitated, and settled on a row of solid, blank black squares.

Not DELAYED. Not CANCELLED. Just empty. As if Line 14 had never existed at all.

Milo stared at the blank space, a cold, unpleasant weight settling into the pit of his stomach. Behind the brass grille, the black Bakelite telephone on the clerk's desk began to ring—a sharp, insistent, metallic sound that echoed down the empty concourse.

The telephone on the clerk’s desk rang a fourth time, then a fifth, each shrill burst of the brass bell echoing off the tiled walls of the lower concourse like a fire alarm.

Milo glanced over his shoulder. Barnaby was watching him from the newsstand, his eyebrows raised beneath the green brim of his eyeshade. Down the hall, a pair of station janitors pushing wide, horsehair brooms had paused to lean on their handles and stare. Nobody let a station telephone ring five times. At Void Junction, a ringing phone meant someone was late, someone was leaking, or someone was about to be fired.

Milo looked back through the brass grille-work. The heavy steel door at the rear of the booth remained stubbornly shut. The chattering teletype machine had stopped, leaving a long tongue of perforated paper hanging limply over the edge of the desk.

On the seventh ring, Milo sighed, reached his arm through the widest gap in the brass bars, and stretched his fingers until he could just hook the Bakelite receiver off its cradle. He dragged it toward the grille and pressed it to his ear.

"Dispatcher's office, Platform Zero," Milo said.

There was a brief, crackling silence on the line, filled with the distant hum of high-voltage transformers. Then a voice—crisp, nasal, and entirely devoid of patience—snapped back. "Who is this? Where is Miller?"

"Miller stepped out to powder his nose," Milo said, leaning his elbow on the counter. "This is Vance. Captain of the Lucky Penny, Track Zero. I'm standing here waiting for my water chit and my return clearance, and your departure board just swallowed my line."

"Captain Vance?" The voice paused. Papers rustled on the other end of the line. "You're not supposed to be on that extension. Put Miller back on immediately."

"I'd love to, pal, but he vanished behind a steel door five minutes ago. Now, about Line Fourteen—"

"Line Fourteen is no longer a matter for the Platform Zero dispatcher," the voice said, cutting him off cleanly. "Do not attempt to take on heavy water. Do not attempt to board passengers or load outbound freight. Keep your locomotive coupled to the hydraulic stops and wait for further instructions."

Milo frowned, his grip tightening on the receiver. "Wait a minute. I've got twelve boxcars of Ganymedean ice-melons that are going to turn into lukewarm soup if I don't get them to the Ceres transfer hub by Tuesday, and I've got three cages of Martian rock-badgers in the tender that are starting to wake up. Who is this?"

"This is the Office of the Atomic Timetable," the voice replied, as if that explained everything, and perhaps in Void Junction, it did. "Stay by your train, Captain."

The line went dead with a sharp, final click.

Milo stood holding the silent receiver for a moment, listening to the empty buzz of the wire, before carefully reaching back through the bars to drop it onto the cradle. Just as he pulled his arm back, the steel door at the rear of the booth swung open.

Miller, the young clerk, stepped back inside. He didn't look at Milo. He walked straight to his desk, picked up the pale blue pneumatic slip he had left there, and slid it into a locked drawer.

"I've been instructed to inform you," Miller said, still staring at his blotter, "that your departure slot has been suspended pending an administrative review. You are not to move the Lucky Penny from Track Zero."

"Yeah, I got the gist from the voice on the phone," Milo said. "What's going on, Miller? Did somebody upstairs forget to carry a zero? Line Fourteen has been running the Ganymede-Io milk run since before you were in short pants."

Miller finally looked up. Behind his thick horn-rimmed glasses, his eyes were flat and rehearsed. "The Timetable does not forget, Captain Vance. If you have a grievance, you may file Form 88-A with the Bureau of Schedules on the Main Concourse. Good morning."

He turned his back, sat down on his stool, and fed a fresh roll of paper into the teletype. The machine immediately began to clatter, drowning out whatever else Milo might have said.

Milo stood at the window for three seconds, debating whether to reach back through the bars and rattle the kid's teeth, then decided against it. Assaulting a station clerk carried a mandatory six-month stint in the lunar salt mines, and Milo's knees couldn't take the low-gravity damp.

He turned on his heel and walked back toward the swinging doors of Platform Zero, pausing only briefly at the newsstand.

"Bad news?" Barnaby asked, not looking up from the stack of Popular Atomics magazines he was straightening.

"Somebody upstairs took an eraser to Line Fourteen," Milo said. "Tell me something, Barnaby. You've been breathing this recycled air for thirty years. You ever seen the board just blank out a whole line? Not delayed, not cancelled—just gone?"

Barnaby stopped straightening the magazines. He looked left, then right, checking the empty concourse before leaning across the counter. "Once," he said quietly. "Back in '48. The Titan Belle. Old Class-B ore hauler. Board went blank at noon. By four o'clock, the Stationmaster's boys were out there with cutting torches, stripping her down for scrap."

Milo felt a cold draft that had nothing to do with the station's air conditioning. "The Belle was eighty years old and her containment vessel was cracked."

"Sure," Barnaby said, nodding slowly. "And the Lucky Penny is a spring chicken, right, Skipper?"

Milo didn't dignify that with an answer. He pushed through the swinging doors and stepped back out onto the oil-stained concrete of Platform Zero.

The Lucky Penny sat at the end of the track, looking smaller and more battered than usual under the buzzing fluorescent tubes. Steam was venting lazily from her auxiliary relief valve, curling up toward the dripping condensation pipes overhead. Gus was standing near the tender, a heavy brass wrench in one hand and a clipboard in the other, arguing with a station porter in faded blue coveralls.

"I'm telling you, the manifest says six tons of heavy water!" Gus was shouting over the hiss of the steam. "You can't just turn off the pump!"

"I don't make the rules, kid," the porter said, shrugging. "Red light came on at the manifold. Means no juice, no water. Take it up with the brass."

"Hold off on the water, Gus," Milo called out, walking up to them.

Gus turned, his round face streaked with fresh grease. "Skipper! Tell this guy to open the main valve. If we don't top off the moderator tanks, we'll be running dry halfway to the Belt."

"He can't open it," Milo said, glancing at the porter, who nodded gratefully and beat a hasty retreat toward the freight elevator. "They froze our clearance."

Gus blinked. "Froze it? Why? We were only one second late! I've seen the Europa Ice come in twenty minutes behind schedule and they still gave her a full wash-and-wax!"

"It's not about the second," Milo said, looking up at the dark, blank rectangle on the departure board. "Go ahead and finish unloading the ice-melons and the drill bits. Leave the rock-badgers in the tender for now—they're quieter in the dark anyway. And keep the pile at minimum idle. Don't let the core temperature drop below four hundred, or we'll spend half a day coaxing her back up to critical."

"Where are you going?" Gus asked, wiping his hands on a rag.

"Upstairs," Milo said, buttoning his heavy woollen coat. "Somebody in the Scheduling Office has their slide rule jammed up backwards, and I'm going to help them pull it out."

To reach the Main Concourse from Platform Zero, one did not take the grand, sweeping marble staircases that carried first-class passengers from the luxury berths to the dining halls. One took Freight Lift C, a cage of rattling iron mesh that smelled of wet wool, machine grease, and the faint, lingering aroma of the Martian livestock that occasionally rode it up to the quarantine pens.

Milo pulled the brass gate shut and shoved the lever to UP. The lift groaned, shuddered, and began its slow ascent through the belly of Void Junction.

Through the gaps in the ironwork, Milo watched the strata of the station pass by. First came the sub-levels: miles of humming copper busbars, thick lead-shielded coolant pipes pulsing with heavy water, and dark, cavernous storage bays stacked to the rafters with crates of dehydrated rations and spare reactor rods. Then came the maintenance decks, where men in asbestos suits hurried along catwalks with welding torches and radiation counters.

Finally, with a heavy clunk and a hiss of pneumatic cushions, the lift stopped at the Main Concourse.

Milo pushed the gate open and stepped out, instantly feeling as though he had wandered onto the set of a big-budget Hollywood picture in the wrong costume.

The Main Concourse was a cathedral of 1950s atomic optimism. The floor was polished white terrazzo, inlaid with sweeping brass lines that mapped the orbital paths of the inner planets. Overhead, a vaulted ceiling of arched steel and tinted glass rose eighty feet into the air, painted with a sprawling mural of gleaming silver rockets, smiling astronauts, and stylized atoms with orbiting electrons. The air here didn't smell of boiled cabbage and hot oil; it smelled of lemon wax, expensive French perfume, and fresh-roasted coffee drifting from the Starlight Lounge.

Passengers in tailored suits and mink stoles strolled past, their leather luggage gliding effortlessly behind them on magnetic hover-carts. A uniformed bellhop in crisp maroon and gold marched by, ringing a tiny silver chime and calling out, "Final boarding for the Venusian Zephyr, Platform One! Departing on the dot at 05:00!"

Milo looked down at his own grease-stained boots, which were leaving faint, dark smudges on the pristine terrazzo. He adjusted his peaked cap, tucked his thumbs into his belt, and headed toward the center of the concourse, where the Master Chronometer stood.

The Master Chronometer was the heart of Void Junction. It was a towering, four-sided obelisk of brushed chrome and black marble, rising thirty feet from the center of the floor. On each face, a massive clock dial glowed with soft, radioactive green light, its sweep-second hand moving with a silent, hypnotic precision. Beneath the dials, a series of glass windows revealed the inner workings: not gears and springs, but a mesmerizing array of pulsing vacuum tubes, spinning magnetic drums, and tiny, flickering neon relays.

Every clock on the station, from the luxury suites on Deck Four to the grease-pit timers on Platform Zero, was slave to this machine.

Milo skirted the crowd of tourists snapping photographs of the obelisk and headed toward a pair of tall, frosted-glass doors set into the far wall. Above the doors, cast in heavy bronze Art Deco lettering, were the words: BUREAU OF SCHEDULES – AUTHORIZED PERSONNEL ONLY.

He pushed the doors open and stepped into a world of paper and humming electricity.

If the Main Concourse was a cathedral, the Bureau of Schedules was its monastery. The room was vast, dimly lit, and intensely hot, cooled only by a bank of oscillating brass fans that did little more than push the smell of hot bakelite and ozone from one side of the room to the other.

Rows of identical metal desks stretched away into the gloom, each manned by a clerk in a crisp white shirt, black tie, and green celluloid eyeshade. There was no idle chatter here. The only sounds were the rhythmic, deafening thwack-clatter-whir of dozens of punch-card sorters, the sharp ping of mechanical calculators, and the constant, pneumatic whoosh-thump of brass cylinders shooting through the overhead glass tubes.

At the front of the room, behind a low wooden railing, stood a long reception counter. Behind it sat a woman with iron-gray hair pulled into a bun tight enough to give a statue a headache. She was stamping a stack of pink manifests with a heavy, rhythmic thud-thud-thud.

Milo walked up to the railing, took off his cap, and rested his forearms on the wood. "Morning, ma'am. Captain Milo Vance, Lucky Penny, Track Zero. I'm looking for whoever just zeroed out Line Fourteen."

The woman didn't break her rhythm. Thud. Thud. Thud. "Do you have an appointment, Captain?"

"I had a departure at 05:05," Milo said, gesturing vaguely toward the clock on the wall. "That's in forty minutes. I'd like to make it."

She stopped stamping, set the rubber stamp neatly on its ink pad, and looked at him over the rims of her half-moon spectacles. Her gaze took in his lead-lined coat, his grease-stained trousers, and the faint smear of axle oil on his chin.

"Line Fourteen," she said, her voice like dry leaves scraping across concrete. She reached behind her, pulled a thick, cloth-bound ledger from a rack, and flipped it open. Her finger traced down a column of tightly printed numbers. "Locomotive 404. Lucky Penny. Class-C Freight. Registered to... M. Vance."

"That's me."

"Your line has been marked for Timetable Reallocation," she said, closing the ledger with a soft thump. "You will receive your formal notice in due course. Until then, your vessel is restricted to Platform Zero."

"Reallocation?" Milo leaned forward. "Lady, I don't know what that means in Bureau-speak, but I've got three tons of ice-melons and a crate of badgers—"

"It means," a new voice interrupted, smooth and oily as a freshly greased bearing, "that the Atomic Timetable no longer requires your services, Captain Vance."

Milo turned. A man had stepped out from a glass-walled office at the side of the room. He was tall, thin, and wore a tailored gray suit that looked like it cost more than Milo made in six months. A gold pocket-watch chain stretched neatly across his vest, and a silver slide rule was clipped into his breast pocket like a badge of office.

"Mr. Pendelton," the woman at the counter said, nodding stiffly. "I was just explaining—"

"Thank you, Miss Gable. I'll handle this." Pendelton offered Milo a thin, practiced smile that didn't reach his eyes. "Captain Vance. Come inside, please. You're blocking the pneumatic drop."

Milo followed Pendelton into the glass-walled office. It was slightly cooler than the main floor, thanks to a dedicated air-conditioning unit rattling in the corner, and the walls were covered with massive, framed charts of the solar system. Red, blue, and yellow lines crisscrossed the black void between the planets, curving in elegant, sweeping arcs—the orbital rail corridors.

Pendelton sat behind a sprawling mahogany desk, folded his hands, and gestured to a straight-backed wooden chair across from him. Milo remained standing.

"Suit yourself," Pendelton said, leaning back. "I'm Arthur Pendelton, Deputy Director of the Atomic Timetable. And before you ask, no, there has been no clerical error. Your line was flagged by the Chronos-IV computer at 03:42 this morning."

Milo stared at him. "The Chronos-IV? That big pile of vacuum tubes upstairs? What does a glorified adding machine know about running freight to the Belt?"

Pendelton's smile hardened a fraction. "The Chronos-IV is not an adding machine, Captain. It is a fourth-generation atomic logic engine. It calculates every orbital trajectory, every gravitational perturbation, every fuel-to-mass ratio, and every docking window across twelve billion miles of space. It keeps thirty-four thousand locomotives from colliding in the dark. It keeps Void Junction in perfect time."

"And it decided to erase Line Fourteen?"

"It decided," Pendelton said, pulling a long, rectangular punch card from a brass tray on his desk, "that Line Fourteen is mathematically obsolete."

He held the card up between two fingers. It was covered in neat rows of tiny, rectangular holes.

"Let's look at the numbers, Captain," Pendelton continued, glancing down at the card. "The Lucky Penny is forty-one years old. Her specific impulse has dropped twelve percent over the last five years. She burns fifteen percent more heavy water per light-minute than a modern Class-B hauler. Her cargo capacity is twelve cars, half of which are usually filled with low-margin agricultural freight—ice-melons, rock-badgers, mining bits."

"People in the Belt need to eat, Pendelton. And they need drill bits to dig out the ore that pays your salary."

"And they will get them," Pendelton said smoothly. "Faster, cheaper, and more reliably. The Chronos-IV has consolidated the Ganymede-Io milk run into the new Jovian Arrow express line. A Class-A turbine locomotive will be taking over your route starting tomorrow. It makes the run in half the time, carries three times the tonnage, and doesn't arrive one second late."

Milo blinked. "One second? You're grounding me over one second?"

"I'm grounding you over forty-one years of entropy, Captain," Pendelton said, setting the punch card down on the desk. "The Timetable is absolute. Every second a slow, leaking, forty-year-old kettle like the Lucky Penny occupies a magnetic rail-spoke, she creates a ripple in the schedule. A ripple becomes a delay. A delay becomes a bottleneck. And a bottleneck, at seventy thousand miles per hour, becomes a catastrophe."

Milo looked at the framed charts on the wall. To Pendelton, those red and blue lines were just geometry. They didn't have names. They didn't have crews who spent three weeks at a time eating tinned beans over a hot uranium core, listening to the bulkheads groan in the dark.

"I've been running that line for eighteen years," Milo said, his voice dropping an octave. "I know every rogue ice-chunk between Mars and Callisto. I've pulled three stranded ore-barges out of the Jupiter trojans when your shiny Class-A expresses wouldn't even slow down to wave. You can't just punch a few holes in a piece of cardboard and tell me my train doesn't exist."

"I didn't tell you that, Captain," Pendelton said, reaching for a fountain pen. "The Timetable did. Now, if you'll excuse me, I have forty-two other lines to audit before the 06:00 shift change. Remain on Platform Zero. The Stationmaster's office will issue your formal decommission paperwork within the next few hours."

Milo stood there for a long moment, his jaw clenched so tight his teeth ached. He looked at the punch card on the desk, then at Pendelton's smug, freshly shaved face. He knew better than to argue with a bureaucrat. You couldn't reason with a man who wore a slide rule like a crucifix.

"Don't lose that card, Pendelton," Milo said quietly, turning toward the door. "You might need it to figure out who's going to haul your freight when the Jovian Arrow throws a turbine blade halfway through the Belt."

Pendelton didn't look up from his papers. "Good day, Captain Vance."

The ride back down in Freight Lift C felt twice as long as the ride up.

Milo leaned against the rattling iron mesh, his cap pulled low over his eyes, watching the gleaming, sunlit world of the Main Concourse vanish above him, replaced once again by the dark, sweating pipes and humming cables of the station's underbelly.

He stepped out onto Platform Zero and walked slowly back toward Track Zero. The platform was quieter now. The Io-Europa local had departed, leaving the cast-iron benches empty save for a single, sleeping drifter curled up with his head on a canvas duffel bag.

At the end of the track, the Lucky Penny sat in her pool of Cherenkov blue light, looking like an old, tired workhorse waiting for the knacker's yard.

Gus was sitting on the bottom rung of the cab ladder, tossing a small, rubber ball against the side of the tender and catching it. When he saw Milo approaching, he stood up, his face eager.

"Well?" Gus asked. "Did you straighten 'em out? Are we getting our water?"

Milo stopped beside the locomotive's massive driving wheels. He reached out, placing a gloved hand against the warm, vibrating iron of the boiler casing. Beneath his palm, he could feel the steady, rhythmic pulse of the uranium pile—a heartbeat he had listened to for nearly two decades.

"No water, Gus," Milo said, keeping his voice level.

Gus's smile faded. "No water? What do you mean, no water? How are we supposed to make the Belt?"

"We're not," Milo said. "Not at 05:05, anyway. They've pulled our slot."

"Pulled it? For how long?"

Milo looked past Gus, up at the big split-flap departure board hanging over the swinging doors. The blank black space where LINE 14 had been stared back at him like a missing tooth.

"Until further notice," Milo said. "Go on up to the cab and brew a pot of coffee. The real stuff, not that automat tar. Looks like we're going to be sitting on Platform Zero for a while."

Gus frowned, clearly wanting to ask a dozen more questions, but something in Milo's tone stopped him. He nodded slowly, turned, and climbed back up the iron ladder into the cab.

Milo stood alone on the concrete, listening to the hiss of the station's cooling towers and the distant, muffled roar of another express train thundering through the luxury platforms overhead. He reached into his coat pocket, pulled out his brass pocket watch, and snapped the lid open.

The radium-painted hands glowed softly in the gloom. 04:48:12.

Right on time. And nowhere to go.
