Big day here in Utrainia, and the result of many days work. First of all though, a little bit of background...
While building the bridge module I could feel that I was very close to making a complete loop of modules, all I needed was this and one more corner module. At that point I realised I had another corner module, my previous base for the bridge module. So I had the required number of corners, however neither had track, and it would take me a while to complete the bridge scene. I felt frustrated that I was so close, yet so far.
Then it struck me that I could cheat a little... if I tacked down some track on each module, they could act as stand-ins until I got around to completing them. Hmm...
So that night I quickly made up a pair of spacer modules. The first one I just put down some track over the existing foam, on the second one (the new bridge module) I made some joists out of 3mm MDF and a tack base from some foam board. End result was two corner modules...
