About this 3D model

This is a remix of http://www.thingiverse.com/thing:252368 I just popped one bent out of the trestle bridge assembly and created a few versions that can be printed one by one, upright or flat on the build platform. This first version is in O scale or 1:48. It could be scaled down to other sizes. For S scale reduce to 75%. For HO scale reduce to 55%. For N scale reduce to 30%. I think... ;)
