PCC Rapid Transit Cars

The BMT's Clark-built train of 1940 (Bluebird) may be the first rapid transit car to employ PCC patents.  It is certainly the first articulated PCC car.  The Bluebird web site is:

One truck in which a TRC patent was employed that was not classified as a "B", was the Model E.  This truck was developed by collaboration of TRC, Clark, and General Steel Industries (GSI) for application under the Budd-built R-11 train of 1949.  This truck had no swing links, instead employing lateral deflection of the secondary coil springs of the bolster in keeping with TRC patent 2590033.  Other features of the truck unique to New York - the right angle drive and the drum-type friction brake (later replaced by a Budd disc brake under contract R-34) were not in keeping with any TRC patents, but the use of the one patent would make it appropriate to call these cars PCC cars, in this case PCC Rapid Transit cars, not streetcars.
