EVOLUTION OF A NEW TRUCK DESIGN FOR NEW YORK CITY TRANSIT AUTHORITY

This paper describes the specification, design, and testing required to develop the new lightweight air spring truck design for cars presently under construction for the New York City Transit Authority (NYCTA) under Equipment Contract R-46. The design is of particular significance since the trucks are part of the largest rail passenger car contract in history and for the largest rapid transit property in the world. This paper also summarizes the design characteristics of trucks which have been operating under transit cars on the New York City Transit System during the past seven decades.
