I am working on a 4x8 layout and planning to have bridges extend over a small stream. One of the bridges I want to use is a girder bridge, and bought Lionel's metal girder bridge #6-12730. When I purchased it online I thought it was compatible with FasTrack, but the bridge seems to be about 3/16" too narrow, give or take.
Do I have any options to make this work aside from returning? I was thinking of taking a 10" piece of FasTrack and whittling down the sides to make it fit and semi-permanently fixing it to the bridge, but I've never done anything like this with plastic before. Thanks for reading.
Edit: not sure the best subforum to put this topic in, since it's related to the bridge I thought it was a structural topic, but in retrospect maybe not...
