funding for railroad projects. As a result, the PWA provided fund-
ing for Goodyear-Zeppelin to develop a new train of lightweight aluminum railcars for the New Haven. The prod- uct was initially to be called the “Goodyear Rail Zeppelin” with con- struction number GRZ-1, but the rail- road instead named it the Comet. The design was developed through wind tunnel tests, and had several aircraft- like features. The train incorporated tubular construction, with a smooth underbody just ten inches above the rails. Wind resistance was minimized with no protruding rivets, flush mounted windows, plug type doors, and flush rubber diaphragms between the cars. The aluminum construction resulted in a total weight for the three- car, 207-foot long train of only 126- tons, with a center of gravity 25 inches lower than conventional passenger equipment. Each of the two end power cars
housed a Westinghouse model 3-E 400 h.p. six-cylinder diesel engine between the cab and seating section. These
were replaced with Hamilton diesels in 1947. The engines could be operated from
the controls in either end cab. Each en- gine powered the two traction motors on the GSC cast steel truck at that end of the train. The two trucks between the end units and the articulated cen- ter passenger car were not powered. Every truck had roller bearings and in- cluded aircraft landing gear type shock absorbers to smooth the ride. All of the transverse seats were walkover type, so with the double-ended design, the engineer had only to walk to the oppo- site cab, and a trainman had to walk the aisles reversing the seats, to ready the train for the return trip. The train had seating for 160 pas- sengers, but did not have a dedicated baggage room or provision for food ser- vice. Mechanical air conditioning was installed for passenger comfort, and the Number 2 power car also included a steam boiler for train heating. The 9′-10″ width of the train allowed for wider seats and aisles as compared to the earlier streamliners. Interior colors
