Howdy Bob, you might contact Tom about his neat open passenger car. I got one in 1:35n2 and it is a beauty.
Before & after shots. All I had to do was attach trucks & bolsters, couplers, paint, and desperadoes.
And it wasn't expensive either. Tom has some short cars like this which might be more what you want. Check his Shapeways listing.
