STANDARD HEATING SYSTEM. This system has as its basis the ordinary hot watercirculating system, with the Baker heater stove. Theheat of the fire in the stove being replaced with steam HEATING AND LIGHTING CARS 61 drawn, from the locomotive; of course the fire in theBaker heater stove may be started whenever use the steam thus drawn from the locomotive steamjackets are used, one being located near the heater, on. thepipe which leads to the bottom of the coil, the otherson the pipes which lead to and from the radiating pipeson the side of the car opposite the heater side, knownas cross-overs, or, in the case of a double circulation 62 RULES FOR MOVEMENT OF TRAINS car they are connected into the circulation near the mid-dle of the car. The steam thus drawn from the loco-motive is conducted from car to car by means of «iiitableflexible couplings and pipes beneath the floor; thesepipes are called train-pipes, and they are so arranged asto admit of gravity drainage from a selected high pointto each end of the car. A fitting is placed at this highpoint which permits the necessary quantity o^f steam tobe withdrawn from the train-pipe for use in heating thecar. Two train-pipe valves, Figure lo, one at each endof the car, control the passage of steam through the pipe,both being kept open, except the one at the rear endof the rear car, which shoul
