Tuscan (freight-car red)
These are wooden, externally-braced, single-sheathed, box car. PRR cars seem to have retained the vertical brake staff.
The next photo is of a PRR GTC26. There were twenty of these cars which were X26 box cars that had their roofs removed so that they could be used as high-sided gondolas for coke transportation services. They were suitable only for use with coal-dumping machines. They were in use for about ten years starting in 1953.
