The small hole near 100 RULES FOR MOVEMENT OF TRAINS the top of the directing bend is there to release any airthat might otherwise accumulate at that point when thepipes are being filled with water. Steam is taken from the train-pipe through an inch anda quarter pipe to the inside of the car. From that pointan inch pipe goes to the top of the heater where it isconnected by two separate valves to the one inch FIG. 32B. SECTIONAL VIEW DUPLEX COILS. Through these inner coils the steam passes out atthe bottom to drip pipes which run directly to the the two sides of the car are separate and may becontrolled independently of each other. The temperatureregulator is placed at a convenient point near the system of hot water circulation with vertical trapsis shown in Figure 34. It will be noticed that the planof piping is the same as that shown in Figure 33 withthe exceptions as follows: The vertical style is shownin place of the automatic tee trap, and instead of the endtrain pipe valve step attachment a platform operating-mechanism is substituted.
