The Last Train After the Apocalypse

Chapter 7 : The Price of Fuel

The sound was not a roar, but a wet, rhythmic slithering, like thousands of tiny, lidless eyes dragging themselves across glass. Matheus didn't wait to see what happened when the creature finished blinking.

"Run!" he screamed, his voice cracking against the ceiling of the cavern.

Carolina was already mid-stride, her boots hammering against the rubbery floor. They sprinted back toward the narrow, pressurized corridor, the energy relay clutched tightly to Matheus’s chest. Behind them, the air pressure in the room spiked, creating a vacuum that threatened to pull the very breath from their lungs.

"Don't look back!" Carolina yelled, ducking into the corridor. "Just keep your eyes on the light!"

They scrambled through the twisty, dark tunnel, their lungs burning as if they were inhaling powdered glass. Matheus didn't stop until they burst out into the wreckage of the Iron Horizon. The cold air of the cavern hit them like a physical blow. He lunged toward the mangled, central console, shoving the relay into the emergency feed slot.

"Take it! Just take it!" Matheus pleaded, his hands shaking as he slammed the locking mechanism shut.

Nothing happened.

The console remained dark. The vibrant purple energy of the relay pulsed once, then died, as if the train had simply rejected the offering.

"Why isn't it working?" Carolina leaned against the shattered frame of the carriage, her chest heaving. "We grabbed the stabilizer. We did exactly what the readings said to do."

Matheus pounded his fist against the dead brass. "It’s not enough. It’s never enough. The train doesn't want electricity. It doesn't want fuel."

"Then what does it want?" she snapped, wiping soot from her forehead with a trembling hand. "We’re sitting ducks in the middle of a predator’s nest. If that thing reaches this wreckage, we’re finished."

A low, melodic chime echoed from the console. A single, amber line flickered to life on the screen, scrolling a text Matheus hadn't seen before.

Requirement: Human warmth detected at sub-optimal levels. Resonance protocol: Required.

"Resonance protocol?" Matheus muttered, his voice hollow. "What is that supposed to mean?"

Carolina crawled closer, squinting at the cryptic amber text. "Warmth? It’s talking about heat, right? Maybe we need to jump-start it with a thermal charge?"

"No," Matheus said, a cold dread settling in his stomach. He looked at his own reflection in the cracked viewport. He looked thin, translucent, like he was fading into the background of this nightmare. "It’s not literal heat. It’s… it’s me. It wants something from me."

"Talk to it, then!" Carolina urged, glancing nervously toward the darkness of the cavern. "Whatever it wants, give it! I’m not dying as a snack for a multi-eyed horror because you’re holding onto your secrets."

Matheus let out a shaky, mirthless laugh. "Secrets? I don't even have a life left to have secrets about. I told you, I’m just an accountant. I don't know who I am anymore."

"Then figure it out!" Carolina stood up, her grip on her pry-bar white-knuckled. "Think, Matheus! Who were you before you climbed onto this train? What hurt you? What are you afraid of?"

The train groaned. Outside, the shadows of the cavern began to lengthen, reaching toward the wreckage like questing fingers.

"I… I had a sister," Matheus whispered, the words feeling heavy and strange on his tongue. "Her name was Elena. I haven't thought about her in… I don't know how long."

The screen flickered. A tiny, faint blue line appeared, pulsing once.

"Keep going," Carolina whispered, her voice softening. "What happened to her?"

Matheus closed his eyes, his breath hitching. "She was sick. For a long time. And I… I was always at the office. I was always working, trying to make enough to cover the insurance, the treatments, the debt. I told her I’d visit every weekend, but the company moved the tax cycle and I… I missed the last one."

He gripped the edges of the console so hard his knuckles bled. "I was on a train. A commuter train. I was looking at a spreadsheet on my laptop, thinking about how I could maximize the quarterly return, and my phone rang. It was the hospital. They said she’d passed."

The amber text on the screen dissolved, replaced by a soft, warm glow. The console began to hum—a deep, resonant sound that felt like a long-forgotten cello.

"I didn't even say goodbye," Matheus sobbed, the words tumbling out, sharp and jagged. "I was just staring at the numbers. I treated my life like an accounting error. And when I finally looked up… I was here. In this gray, empty world. Maybe I deserve this. Maybe this isn't a prison. Maybe it’s just the reflection of how empty I actually am."

The entire carriage shuddered. A bright, incandescent blue light surged through the wires, lighting up the cabin with the intensity of a dying sun. The engine beneath the floorboards erupted into a cacophony of rhythmic clanking and hissing steam.

"It’s working," Carolina gasped, shielding her eyes. "Matheus, you’re doing it! It’s consuming the emotion!"

"I hate it," Matheus cried, his body sagging as the energy drained from his chest, leaving him feeling cold and hollow. "I hate that this is what it takes to move. Why does it have to feed on my guilt?"

"Because in this place, nothing is free," Carolina said, her voice filled with a strange, tragic pity. She grabbed his arm, pulling him upright. "You’re an architect, Matheus. You’re building the road with your own ghosts. It’s horrific, but it’s real. And it’s the only way we’re getting out of here."

The Iron Horizon gave a violent jerk. The wheels, buried deep in the bone-dust of the cavern floor, began to spin. Sparks showered the interior, turning the darkness into a spectacle of blue and gold.

"Get to the throttle!" Carolina commanded, shoving him toward the main control lever.

Matheus scrambled, his movements fluid despite his exhaustion. He gripped the lever, feeling the surge of raw, kinetic potential flowing through the metal. It was no longer just a machine; it was an extension of his sorrow, a physical manifestation of his regret.

"Hold on!" he shouted to Carolina.

The train surged. The wreckage tore free from the cavern wall, metal screeching against stone in a sound that threatened to shatter the earth. They blasted out of the subterranean pit, the tunnel walls blurring into a streak of obsidian and moss.

As they rocketed toward the surface, the air pressure shifted. The temperature inside the cabin plummeted, and the scent of sulfur was replaced by something sharp, clean, and impossibly cold.

The train burst into the open air—but it wasn't the gray, ashen wasteland anymore.

Matheus stared through the shattered glass, his breath hitching. They were flying across a vast, endless tundra of vibrant, iridescent snow. The sky above was a swirling canvas of emerald and violet auroras, and in the distance, towering glaciers carved from translucent crystal stretched toward an infinite horizon.

"Where are we?" Carolina whispered, stepping to his side, her breath fogging in the sudden, biting cold.

Matheus looked at his hands. They were still trembling, still faint, but the blue light of the engine pulsed in time with his own heartbeat. He felt the vastness of the tundra calling to him, a landscape of crystalline silence waiting to be shaped.

"I don't know," Matheus replied, his voice barely a whisper. "But I think the train just decided that we needed a change of scenery."

The Iron Horizon hummed, a low, contented vibration that seemed to promise more miles, more history, and more tolls to be paid in blood and memory.

Matheus looked out at the frozen beauty, a single tear tracking through the grease on his cheek, freezing instantly in the bitter air. He reached for the throttle, his gaze hardening. He wasn't just an accountant, and he wasn't just a driver anymore.

He was the one who had to carry the memories of the dead across the void. And as the train pushed deeper into the shimmering ice, he knew, with a certainty that chilled him to the bone, that the road ahead would be far longer than he had ever imagined.

"Keep it steady, kid," Carolina murmured, leaning against the cold metal. "We’ve got a long way to go."

Matheus nodded, his eyes fixed on the horizon, watching as the crystal mountains shifted and rearranged themselves, following the path he was writing into existence. The journey had only just begun.
