I Initially plan to do a ballast deck bridge, but I receive some comments on that over on TTnut Forum, so since no one makes bridge track tie section for TT Scale. I drew one up and had it printed
Ties are12' long. Rail is ME code 55. The rail press fit into the rail alignment clip nicely, so a little glue should do it.
There are 20', 40' and 60' section 12' wide available on my Shapeways site KD Models
