SUBJECT: Braking Systems, Evaluation
ABSTRACT: In December 1983 a prototype of Portland, Oregon 1 s Tri-County Metropolitan Transit Authority (TRI-MET) light rail vehicle was sent to the Transportation Test Center in Pueblo, Colorado for Specification Compliance and Performance Evaluation. Since this vehicle was a preproduction prototype, numerous adjustments and modifications were required before the vehicle could operate satisfactorily. One area that required considerable adjustment and modification was the New York Air Brake Company's friction brake system. The purpose of this paper is to describe the problems incurred, the modifications made and to recommend a follow-up investigation for optimum friction brake performance on these transit vehicles.
