BOEING'S STATE-OF-THE-ART CAR: THE BIG TEST BEGINS IN NEW YORK

Two State-of-the-Art Cars (SOAC) operating on New York's Eighth Avenue subway line were produced as vehicles with an overall length of 74 ft. 8 in. and a truck center distance of 54 feet. The lightweight SOAC truck has a cast alloy-steel frame isolated from the axles by rubber-chevron primary springs which eliminate metal-to-metal contact between rail and carbody. The air-bellows secondary springing controls carbody leveling as well as further isolating rail-generated noise. Each truck is fitted with two 175-hp DC traction motors driving through double- reduction helical gears and elastomeric couplings.
