Truss Plank and Cross-Seat Heaters Used The heater equipment of these cars consists of ten GoldCar Heating & Lighting interchangeable deftectorcross-seat heaters No. 405-E and two truss-plank heatersNo. 448-E. Each of these types of heaters has two coilsper heater, and the supports with resistance coils are inter-changeable. It was necessary to have twelve heaters percar so that a coil temperature of 450 deg. Fahr. per coilwould not be exceeded. The cross-seat type of heater wouldhave been used throughout except for the fact that onlyten seats were available for heaters, as of the total of sixteencross seats in the cars, four were utilized for sand boxesand two for air apparatus. The location of the truss-plankheaters overcomes the necessity of having a cabheater nearthe motorman. These
