That's an awesome news Daniel! I bought some of the 3D printed ones from Island Modelworks, but unlike the sample prints he had displayed at the Springfield show (which were very nice), the ones I received were really poorly done. The surface was sticky (probably not rinsed properly after printing, and they warped really badly. The floors are like bananas and the body sides are severely bowed out.
Did the designer get a hold of official drawings (which I was not able to acquire) or he based the model strictly on photos? If she could also print the unusual trucks, that would be a cat's meow! I wouldn't mind getting half a dozen myself.
Iain, the red line is a subway in Boston. These are the purple line commuter trains going to the suburbs farther out than subways.
