This is only a small addition to my extensive PCC truck research.
Transit Research Corporation, St. Louis Car Company and Pittsburgh Railways Company worked on a development of a truck for open track. It was then known as B-3 type. Certain documents indicate that also Chicago was interested in a similar truck but all experimenting eventually took place in Pittsburgh. St. Louis Car Company built two slightly different sets of experimental trucks in 1941. Each set of trucks underwent extensive testing and they were also rebuilt several times which always resulted in two different truck sets. As for the cars which tested the trucks, one set was put under 1225, then modified and put under 1278, then again modified and put under 1613. The other set was first tested under 1248, then modified and went under 1230, again modified and put under 1614. At this point there is no proof, but it is possible that before putting under 1600 series cars, both truck sets spent some time under their previous 1200 series cars.
So at this point we are quite well familiar with life story of these trucks, at least to the point before regular production of B-3 trucks started in 1947. What we do not know is the performance of the experimental trucks. Perhaps there are some records in someone's private hands.
