"'Cos she's closer," he growled. "If he don't shut off steam, anything I may be able to do will be useless. He'll cross the switch and come head on to the collision." A minute later he saw a man's figure swing out from the cab of the locomotive on which his eyes were glued, while a hand was waved in his direction. Then a jet of steam and smoke burst from the funnel, while white clouds billowed from the neighbourhood of the cylinders. Even though it was broad daylight, Jim saw sparks and flashes as the wheels of the locomotive were locked and skated along the rails. "He's seen it; he knows!" he shouted. "But he ain't got time to stop her and reverse away from this spoil train. If that switch don't work there's bound to be a bad collision." There was no doubt as to that point. The driver and fireman aboard the locomotive recognized their danger promptly, and, like the bold fellows they were, stuck to their posts. "Brakes hard!" shouted the former, jerking his steam lever over, and bringing the other hand down on that which commanded the reverse. "Hard, man! As hard as you can fix 'em! Be ready to put 'em off the moment she's come to a standstill. This is going to be a case with us, I reckon. That spoil train's doing fifty miles an hour if she's doing one. We can't get clear away from her, onless----" He blew his whistle frantically, and once more leaned out far from his cab, waving to the solitary figure aboard the flying inspection car. "Onless what?" demanded the fireman brusquely, his eyes showing prominently in his blackened face, his breath coming fast after his efforts; for both hand and vacuum brakes had been applied. "Onless that 'ere fellow aboard the inspection car manages to reach the points in time and switch 'em over. Guess he's tryin' for it; but there ain't much space between him and the spoil train. There's goin' ter be an almighty smash." Thus it appeared to all; for by now men, invisible before, had appeared at different points, and were surveying the scene, holding their breath at the thought of what was about to happen. "Best get along to the telephone and send 'way up to Gorgona for the ambulance staff," said one of these onlookers. "That 'ere passenger train ain't got a chance of gettin' clear away. She ain't got the room nor the time. Fust the spoil train'll run clear over the inspection car, and grind it and the chap aboard to powder. Then she'll barge into the passenger, and, shucks! there'll be an unholy upset. Get to the telephone, do yer hear!" He shouted angrily at his comrade, overwrought by excitement, and then set off to run towards the points for which Jim was making. As for the latter, by strenuous efforts, by jagging at his levers, he had contrived to get his engine to run a little faster, and had undoubtedly increased his lead over the spoil train. He was now, perhaps, a long hundred yards in advance.
