Nextopen wide the valve v and adjust the trap T, so that practicallyonly water escapes therefrom. When the car is warmed upsufficiently, regulate the heat by means of the valve v. 75. Care of System.—When the engine is to be discon-nected from the train at the terminal, open wide the valve V,or the rear train cock, before reaching that station. Leave allvalves wide open, the hose uncoupled, and a fire started in theheater. As regards cleaning out the piping; this is not necessary ifthe system has been kept full of water all summer. If a hot-water system fails to circulate properly, and it is found that thewater level is correct, a test may be made to ascertain whether ornot the system is stopped at some point. To do this, draw oflFthe water, connect live steam to one of the draw-off cocks, and

In Fig. 26 is illustrated a heating system that is espe-cially suitable for sleeping and private cars and also for parlor,dining, caf6, and large postal cars. It is a doiible-circiilationsystem, there being a separate set of piping on each side of thecar. Inside the Baker heater is a double-coil generator, one ofwhose coils connects with the riser R, drum D, and piping p,and the other with R, D, and p; thus, each side of the carhas its own separate circulation. Each set of piping is heatedin three places by jackets, the jacket / serving for bothsets p and
