When a conductor and engineer are called, they report at once at the dispatchers' office, where there is a registry-book which they must sign. Passenger conductors and engineers, as well as passenger-engines, have regular runs, which they always make unless some accident prevents. Freight conductors and engineers are assigned to trains in the order in which they sign the book. There are in the employ of the road two men known as "callers," whose sole business it is to notify the trainmen when they are wanted. For instance, three freight-trains are scheduled to leave, one at ten o'clock, another at 10.10, and a third at 10.20. It is the caller's business to see that the crews for these trains are ready to take the trains out. A freight crew consists of engineer and fireman, conductor and two brakemen. The conductor and one brakeman, known as the rear-man, ride in the caboose. The other brakeman, known as the front-man, rides in the cab of the engine, and makes himself useful by ringing the bell, watching for signals, and so on, when he is not engaged in setting or releasing the brakes, or helping make up the train.
