It was only four hundred yards up to the wreck; but that was enough. Masters and his firemen left their train and went to get a view at close quarters. When it was all over, it was up to the wrecking boss and the engine crew of Number Two. Flannagan swore he blocked the trucks of the cars on the incline; but Flannagan lied, and he got clear. Masters and his mate had no chance to lie, for they broke rules, and they got their time. Be that as it may, Bunty sat on the driver’s seat of the Imperial Limited and watched the engineer and fireman start up the track. He lost sight of the men long before they reached the wreck. They were still in view, but he was very busy: he was playing “pretend.” Bunty’s imagination was vivid enough to make the game a fascinating one whenever he indulged in it, and that was often. But now it was almost reality, and his fancy was little taxed to supply what was lacking. He was engineer of the Limited, and they had just stopped at a station. He leaned out of the cab window to get the “go-ahead” signal. Then his hand went through the motion of throwing over the reversing-lever and opening the throttle. And now he was off; faster and faster. He rocked his body to and fro to supply the motion of the cab. He sat very grim and determined, peering straight ahead. He was booming along now at full speed. They were coming to a crossing. “_Too-oo-o, toot, toot!_” cried Bunty at the top of his shrill treble, for the rules said you must whistle at every crossing, and Bunty knew the rules. Now they were coming to the next station, and he began to slow up. “_Ding-dong, ding--_” _BANG!_ Bunty nearly fell from his seat with fright. Ahead of him, up the track, there was a column of smoke as a mass of wreckage rose in the air, and then a crash. Flannagan had blown up a car. Bunty stared, fascinated, not at the explosion, but at the rear end of the wreck on the grade. He rubbed his eyes in bewilderment, then he scrambled over the side of the seat. He paused half-way off, looking again through the front window to make sure. There was no doubt of it: the cars were beginning to roll down the track toward him. He waited for no more, but rushed to the gangway to jump off. Then he stopped as the story Allan had told about his father came back to him. Bunty’s heart thumped wildly as he turned white-faced and determined. No truly engineer would leave his train; his father had not, and Bunty did not.
