Wax ducked back out into the hallway and ran to the back end of the car. After checking out the doorway, he jumped onto the tracks behind the private car, which was finally rolling to a stop. Then he tapped his metalminds and increased his weight.
 A lot
The gravel sank under his feet as his body became increasingly heavy. He gritted his teeth, flared his metal, and Pushed.
 The car lurched in place as if another train had crashed into it. His Push sent it rattling along the tracks, and Wax let out his breath. His muscles didn’t hurt, but he felt as if he’d slammed into a wall.
He released his metalmind, returning his weight to normal, and Pushed on the rails to pull himself out of the gravel. He almost lost a boot in the process.
 He Pushed against the tracks once more, sending himself chasing after the moving car. Not nearly fast enough, he thought as he dropped to the ground and increased his weight again. The car rocked as he shoved it, then he hopped and followed, repeating the process three more times to get it up to speed. Then finally he Pushed himself all the way up to it, jamming his shoulder against the back wall and using Allomancy on the tracks behind to sustain and increase the momentum.
Ground passed behind in a blur, rows and rows of wooden ties, the steel rails with a continuous stream of metal lines that pointed toward Wax’s chest. He groaned, and moved so his back was toward the wall. Still, the Pushing threatened to crush him, as he couldn’t increase his weight here much or risk ripping up the tracks.
 They shot past a group of horses with a few youths guarding them—the bandits’ extra mounts. Wax raised Vindication and fired a few shots into the air, but the horses were too well trained to spook at the sound.He redoubled his Push as he thought he heard gunfire ahead of him. A moment later, his car slammed into the train proper. Wax let go, dropping to the platform, his back aching. The couplers had engaged, however, and the car remained attached to the rest of the train
