Cars with M24 arch bar trucks: 4250 and 4300. Note that the previous line shows these same cars with M25 trucks. Are we to believe that a few were altered? What were the changes? DamfIknow. But maybe this is a clue to why most of the 4250s and 4300s were scrapped before the 4200s and 4300s. Cars with M26 arch bar trucks: 3700s. Cars with M27 arch bar trucks: 3800s. There were two other arch bar designs shown on drawings: M30 and M245, and I have no idea which cars had them. But we know that M283 and the dump cars had much heavier arch bar trucks, presumably made by Diffco. I have no idea what was under the 6000s either. And when were the 4300 Jones cars converted to K-control? I found a shop drawing showing the revised motorman's platform with K-control and an M-20A brake valve. The drawing was dated August 11, 1928. When did the 3700s get K control? Don't know but I found a drawing for a revised detent plate for the controller for series-parallel control that was drawn in 1918. ]
