THIRD AVENUE’S POOR FINANCIAL CONDITION LED TO ITS CAR BUILDING PROGRAM 75 YEARS AGO (Continued from February, 2012 issue) In the previous issue, we explained how the company began its rebuilding program in 1934. At that time, Third Avenue began the rebuilding of 100 single-truck steel convertibles by lengthening them, installing bolsters, and converting them to double-truck cars. These cars weighed approximately 39,000 pounds and seated 54 passengers. These rebuilds weighed approximately 4,000 pounds less than the older wood and steel cars, which weighed approximately 43,000 pounds and seated 48 passengers. Weight was reduced by using aluminum alloy tubing instead of painted steel pipe and black enameled steel pipe in most of the rebuilt cars. The window sash in all new and rebuilt cars was made of extruded aluminum alloy. The Hunter rubber glazing arrangement provided rounded corners and permitted reglazing without removing the sash. Third Avenue built cars 101 and 301-400 in its own shops. It was able to reduce cost and weight by using mild steel bodies and equipping cars with aluminum alloy stanchions, grab handles, seat back handles, and sash. Cars were equipped with full safety car straight air brake equipment. Instead of the standard spring-loaded safety car controller handle, cars were equipped with a selflapping brake valve housed in a springloaded pedal-operated mechanism. Brakes were released by depressing the pedal and applied by allowing the pedal to rise, serving as a dead man control. Depressing the pedal also closed the entrance door. The brakes could not be released until the rear treadle door was closed. Third Avenue’s engineers 1

also developed a dynamic brake, which was installed on the Yonkers cars operating on extremely hilly terrain. Retardation faded as car speed decreased. It also served as an emergency brake, which could slow down the car if the air brakes failed. Because automatic acceleration was too expensive, the company installed a series-parallel controller where the rate of acceleration was at the discretion of the Motorman. Cars were illuminated by twenty 30-volt bare bulbs in series. If one bulb burned out, it short-circuited internally and the others were slightly brighter. On older cars with five 130volt bulbs in series, all bulbs were dark when one burned out. The 300-series cars weighed 38,100 pounds, nearly 1,000 pounds lighter than the rebuilt 100-series cars.
