3D printed ZM wagon

Package arrived yesterday from Shapeways with the ZM wagon I ordered and my (attempt) at making concrete sleepers. There's a lot of things wrong with the sleepers so it's back to the CAD drawing board.

Meanwhile here's some pics of the ZM wagon:

I put the ZA wagon behind it so you can see the difference.

Bogies are Type 16s, from a UK kit I managed to destroy...

All pretty solid. You can see the powdery type plastic underneath.

Looks like I've got a long weekend project.
