The New 3D Printing Thread

Yes, the bridge has track moulded into it with a male and female connector on the ends as normal...

very nice.  without the ridge lines on the rails, will the engines able to run on the viaduct without trouble especially trackmaster 2 engines ?

Those were pictures of the early prototype, the final version has the ridge lines, although to be fair they do need adjusting to be made a little bigger as currently they are too small.
