Through equipment will rest in the yards from six to twenty-four hours, as an average. The local and suburban trains have a programme of their own, slightly different. The engine that is to make the run will get its train in the first place from the storage yard. It is only a big express run, where the locomotive is privileged to back into the station, to find its train made ready there for it by some fag of a switch-engine. The engine that hauls the local backs its own train into the station, makes its run out upon the line, 15, 25, 50 miles, whatever the case may be, and brings the train back into the station. It kicks the cars out, just beyond the cover of the train-shed and while it is hurrying to the turntable the cars are being hastily swept and dusted. An hour will be allowed the engineer to turn his engine and get his coal and water supply, and then he will start out again on his local run. This performance will be repeated one or more times, before the coaches are sent to the yard for thorough cleaning and stocking, and the locomotive housed for a little rest in the programme. This is not the universal programme, but it is typical. It seems simple; but with the multiplicity of local trains in service, the demands of the regular through traffic, and the special demands that come unexpectedly day after day, that car storage yard has got to be arranged for an economy of operation, as well as with the economy of space in view. Each storage track must be of convenient access and the chances are that a separate tower and interlocking may be set aside for the quick, convenient, and safe operation of the storage yard. In any event, it must be so built as to be worked without interference of any sort on the main line tracks of the terminal. So much for the terminal, in reference to its operation; now let us consider it for a moment from the standpoint of the passenger. The first point to be considered by the engineers who design it is the point that we have just considered--safety and convenience in operation. A terminal might be, and sometimes is, an architectural triumph and a thing of monumental beauty, but a curse and an extravagance as an operating proposition. The architects, the mural painters, the furniture designers and the like are called in last. It is their province to make the setting for the thing the engineers have already created.
