The reversing-lever was in the back notch where Masters had left it when he stopped the train. It was Bunty’s task to reach and open the throttle. He climbed up on the seat and stood on tiptoe. Leaning over, he grasped the lever with both hands and pulled it open. What little science of engine-driving Bunty possessed, was lost in the terror that gripped him. The runaway cars were only a couple of hundred yards away now, and, gaining speed with every rail they traveled, spelt death and’ destruction to the Imperial Limited, if they ever reached her. The men at the top of the grade were yelling their lungs out and waving their arms in frantic warning. The train started with a jolt that threw Bunty back on the seat. For an instant the big drivers raced like pin-wheels, then they bit into the rails, and aided by the grade, Number Two began to back slowly down the hill. Bunty picked himself up, his little frame shaking with dry sobs. The freight-cars had gained on him in the last minute, and had nearly reached him. Again he leaned over for the throttle, and hanging grimly to it, pulled it open another notch, and then another, and then wide open. 901 took it like a frightened thoroughbred. Rearing herself from the track under her two hundred and ten pounds of steam, she jumped into the cars behind her for a starter with a shock that played havoc with the passengers’ nerves. Then she settled down to travel. The Devil’s Slide is two miles long, and some pretty fair running has been made on it in times of stress; but Bunty holds the record,--it’s good yet,--and Bunty was only an amateur! It was neck and neck for a while, and there was almost a pile-up on the nose of 901’s pilot before she began to hold her own. Gradually she began to pull away, and by the time they were half-way down the hill the distance between her and the truant freight-cars was widening. The speed was terrific. Pale and terror-stricken, Bunty now crouched on the driver’s seat. Time and again the engineer’s whistle in the cab over his head signaled, now entreatingly, now with frantic insistence. But Bunty gave it no heed; his only thought was for those cars in front of him that were always there. He cried to himself with little moans. There was a sickening slur as they flew round a curve. 901 heeled to the tangent, one set of drivers fairly lifted from the track. When she found her wheel base again, Bunty, shaken from his hold, was clinging to the reversing-lever. He shut his eyes as he pulled himself back to his seat. When he looked again, he saw the freight-cars hit the curve above him, then slew as they jumped the track and, with a crash that reached him above the roar and rattle of the train, the booming whir of the great drivers beneath him, go pitching headlong down the embankment.
