Except for the ends, this CNJ PBn seems pretty similiar. I used a shortened Rivarossi car, rebuilt the windows from strip styrene to get the single-seat arrangement, MDC trucks, and steps made by stacking styrene I-beams together. Not a contest winning model, but I needed something I could mass produce for my old CNJ layout.

Here's another angle of the same technique used to make a Reading PBr. It's easy to see how the styrene is layered to make the window frames. The glass is a single long strip of clear styrene.

And a close up of the wide commuter steps on right, compared to the narrow Gold Medal ones on the left.
