The work of the yard goes on without intermission day and night, Sundays as well as week-days. The men there employed know no holidays, get no vacations. The loaded cars are coming from the freight-houses all day long, in greater numbers perhaps in the afternoon and evening, but the work of loading and moving cars goes on somewhere or other, at nearly all times. As often as the yardmaster gets together a sufficient number of cars for a common destination to make up a train, he gathers them together, orders a road engine and crew to be ready, and despatches them. In the make up of "through" trains, care has to be exercised to put together cars going to the same point, and to "group" the trains so that as little shifting as possible may be required at any succeeding yard or terminal, where the trains may pass. To accomplish this, a thorough knowledge of all the various routes is necessary, and minute acquaintance with the various intermediate junction yards and stations. The train once "made up" and in charge of the road crew, its progress for the next few hours is comparatively simple. It will go the length of the "run" at a rate of probably twenty miles per hour, subject only to the ordinary vicissitudes of the road. At the end of the division, if a through train, it will be promptly transferred to another road crew with another engine, and so on. Each conductor takes the running slip for each car in his train. He also makes a report, giving the cars in his train by numbers and initials, whether loaded or empty, how secured; and detailed information in regard to any car out of order, or any slight mishap or delay to his train. These reports go to the Car Accountant. The running slips stay with the cars, being transferred from hand to hand until the cars reach their destination. At junction yards where one road terminates and connects with one or more foreign roads, a complete record is kept, in a book prepared especially for the purpose, of every car received from and delivered to each connecting road. A copy of this information is sent daily to the Car Accountant. [Illustration: Freight Yards of the New York Central & Hudson River Railroad, West Sixty-fifth Street, New York.] [Illustration] [Illustration: "Dummy" Train and Boy on Hudson Street, New York.] A road is expected to receive back from a connecting line any car that it has previously delivered loaded. It becomes very necessary to know just what cars have been so delivered. Without such a record a road is at the mercy of its connections, and may be forced to receive and move over its length empty foreign cars that it never had in its possession before, thus paying mileage and being at the expense of moving cars that brought it no revenue whatever. The junction records put a complete check on such errors, and by their use thousands of dollars are saved annually. * * * * *
