No!What's your source of information for the TTC CLRV? The CLRVs do not have the same control equipment as the SEPTA Kawasaki cars. The CLRV control equipment was done by Garrett Air Research and the Kawasakis have Westinghouse Electric. The CLRVs have two monomotor trucks. The Kawasakis have four motor trucks that are somewhat similar to the B2/B3 design used on the PCCs. The CLRVs were, until their couplers were removed in the 1980s, capable of operating in trains of up to six cars, but SEPTA's Kawasakis could only run in trains of two cars. When you look at the CLRV and SEPTA Kawasaki's, they're conceptually similar streetcars but when you look at what's under the floor, you see that they are two very distinct animals. The CLRVs are a few years older and represented something of a departure from various aspects of the PCC design to try out new things, such as the monomotor trucks as an example, wheras the Kawasaki design is more directly adapted from the PCC in that regard. I don't know what the MBTA Type 7 cars have for control equipment but it wouldn't be the same as a CLRV either. -Robert King |
