I have an Auto Reversing set, and love it. Unfortunately the rail on one of my 5-inch A-to-B pieces is broken. My first idea was to slip the rail out and slide in a replacement from another piece of track (I have a lot of A-to-A pieces). But that seems like it may not work — I think the track connections are too fragile.

I'm wondering if I can get a replacement A-to-B piece? Or wondering if someone knows how to make an A-to-B from an A-to-A piece?

Thanks!
Michael.
