Version 2 of my PS-1 40ft boxcar (repaint) kit has just been released. This new model comes with many new and improved parts (ladders, trucks, roofwalks) and also polycount, LOD and materials improvements. For all repainters who are interested there are now also several new child objects to pick from.
The cars come as a stand-alone pack of five PRR lettered models -- the main purpose of the pack though is to be repainted. A LOT of railroad companies had PS-1 40ft boxcars at some point.

You can download the new PS-1 pack here:
