Simmon of the railway department of theWestinghouse Electric & Manufacturing Company. Inany consideration of the economical field of the trolleybus, according to Mr. Simmon, there are many elementsthat enter and some of the more important are the fol- P Operating Costs ■trolley bu5, motor bus AND SAFETY ZO 30 40 HEADWAY - MINUTES 50 lowing: (1) Existing transportation available, (2) arerural or paved roads involved, (3) density of passengertraffic, (4) condition of existing roads, (5) yearly taxburdens for buses, (G) labor and material costs, and(7) power equipment available. The taxicab or service at call vehicles, the gas bus,trolley bus, safety car or double-truck car, all have aneconomical field, and in order to determine roughly whatthese are for gas bus, trolley bus and safety car somecomparative figures have been compiled. In this com-parison it is assumed that the motor bus and trolleybus have the same seating capacity, namely, thirty, andthat the safety car—which is of the single-end type—seats thirty-five. The comparison is then shown in theaccompanying table and curves.
