He had stolen the Velocipede. He had broken into a clapboard building at the edge of Burbank freight depot where the Southern Pacific section inspector stored it and manhandled it onto the rails. In the unlikely event that some cinder dick or village constable saw him and asked what the hell he was doing riding the main line at midnight, his suit and hat would buy him two seconds of hesitation. Ample time to deliver a silent answer with the blade in his boot.

Leaving the lights of Burbank behind, rolling past darkened farmhouses, he quickly adjusted to the starlight. Half an hour later, ten miles north of Los Angeles, he slowed down, recognizing the jagged angles and dense layers of latticework of an iron trestle crossing a dry riverbed. He trundled across the trestle. The rails curved sharply to the right to parallel the riverbed.

He stopped a few yards after he felt the wheels click across a joint where two rails butted together. He unloaded his tools and knelt down on the crushed-stone ballast, cushioning his knees on a wooden crosstie. Feeling the joint between the rails in the dark with his fingers, he located the fishplate, the flat piece of metal fastening the rails to each other. He pried up the spike that anchored the fishplate to the tie with his spike puller. Then he used his track wrench to loosen the nuts on the four bolts that secured the fishplate to the rails and yanked them out. Tossing three of the bolts and nuts and the fishplate down the steep embankment, where even the sharpest-eyed engineer could not see them in his headlight, he threaded the last bolt through a hole in the shank of the hook.

He swore at a sudden stab of sharp pain.

He had cut his finger on a metal burr. Cursing the drunken blacksmith who hadn't bothered to file smooth the edges of the hole he had drilled, he wrapped his finger in a handkerchief to stop the bleeding. Clumsily, he finished screwing the nut on the bolt. With the wrench, he made it tight enough to hold the hook upright. The open end faced west, the direction from which the Coast Line Limited would come.

The Coast Line was a "flyer," one of the fast through passenger trains that sped across long distances between cities. Routed via new tunnels through the Santa Susana Mountains, from Santa Barbara to Oxnard, Burbank, and Glendale, she was bound for Los Angeles.

Suddenly, the Wrecker felt the rail vibrate. He jumped to his feet. The Coast Line Limited was supposed to be running late tonight. If that was she, she had made up a lot of time. If it wasn't, then he had gone to great effort and taken dangerous risks to derail a worthless milk train.

A train whistle moaned. Quickly, he grabbed the spike puller and yanked up spikes that were holding the rail to the wooden ties. He managed to pry eight loose before he saw a glow of a headlight up the line. He threw the spike puller down the steep embankment and jumped onto the Velocipede and pedaled hard. Now he heard the locomotive. The sound was faint in the distance, but he recognized the distinctive clean, sharp huff of an Atlantic 4-4-2. It was the Limited, all right, and he could gauge by the rapid beat of the steam exhausted from her smokestack that she was coming fast.
