The system includes two specialdevices, an electric thermostat operating contacts by the expan-. Electro-Magnetic Valve Electric Thermostat sion and contraction of a temperature-sensitive diaphragm andan electro-magnetic valve. The lowering in the car temperatureby changes in the weather causes the thermostat to open the valve and the warming of the car will operate to close thevalve. The thermostat is usually placed in a convenient loca-tion on the wall near the middle of the car and the valves are placed in the cross-over pipes on each sideof the car underneath a seat, the three being connected byelectric wires conveniently placed. The electro-magnetic valveis normally open. The electric current is very small and is ob-tained from the electric lighting circuit. It is claimed thatthere is a considerable saving in steam accomplished by theuse of this system, either in connection with straight steam orwith plain vapor systems. It is said that in the heating of carsin terminal yards tests have shown a saving of from 50 percent to 75 per cent. PORTABLE ELECTRIC HOI
