How well do they render brick mortar detail?
I have a good number of Pennsy plans for small, basic buildings that would be even less complex than that, David... Would be a great way to try Shapeways out!
Smaller towers, block stations, sheds, freight houses, track bumpers, coal trestles, all of these things could be made into a line of PRR-specific details/structures!
A PRR E44 for a six-axle Alco chasis is also a fantasy of mine; pantograph sold separately, of course!
