Bill grasped it in his mammoth palm and gave it a mighty squeeze.
“’Tain’t fer my own sake,” he added, and his voice was a little husky.
“I know,” said Allan, quickly. “It’s all right. I’ve forgotten it.”
“Thank’ee,” said Bill, awkwardly, and turned away.
Allan watched his burly figure until it disappeared through the door. He was glad that he had taken the engineer’s advice and not reported him. After all, the man was good, at heart; and besides, there were the wife and children.
He waited until he heard the train puff away, reported its departure, and then picked up the book of rules again. He ran over the definitions—definition of “train,” “section,” “extra,” and so on, which there is no need to repeat here—with which, indeed, the readers of this series ought already to be familiar.
Following the definitions came the train-rules, with instructions as to the time-card, and the signal rules. The latter are especially interesting, for every one who has travelled on a railway has noticed the signals made by hand, flag, or lantern, and has no doubt wondered what they meant. A hand, flag, or lantern swung across the track means stop; raised and lowered vertically, proceed; swung vertically in a circle across the track, when the train is standing, back; and there are other signals to indicate when the train has broken in two, and to order the release or application of the air-brakes. Rule No. 13 is that “any object waved violently by any one on or near the track is a signal to stop,” and a stop signal must always be obeyed, no matter at what cost—to run by such a signal means instant dismissal.
There are other signals, too, which are of interest to passengers, particularly the whistle signals. There are sixteen of these, but the more important ones are: one short blast, stop; one long blast on approaching stations, junctions, or railroad-crossings at grade; two long blasts followed by two short ones on approaching public crossings at grade, which is the signal most frequently heard by the travelling public. A succession of short blasts means danger ahead—and is used, too, to scare cows and horses off the track.
There is yet another class of signals, which are given with the signal-cord which runs overhead through every passenger-coach. Every one, of course, has seen this cord, and has also seen the conductor use it to signal to the engineer. It is connected with a little valve over the door of the car, and every time the conductor pulls it, there is a little hiss from the valve as of escaping steam. This is the compressed air escaping. The valve is connected with a compressed-air line which runs through the entire train, and every pull on the cord blows a little whistle in the cab of the engine. Two pulls at this cord, when the train is moving, means stop at once; when the train is standing, two pulls is the signal to start. Four pulls means reduce speed, and five, increase speed. Three pulls is the signal usually heard, and indicates that the train is to stop at the next station. It is always answered by two toots from the whistle to show that the engineer understands. This compressed-air line long ago replaced the old signal-cord which rang a bell in the cab.
