I have created, successfully, perhaps 60 bridges for a new Knoxville Division
(L&N, CSX) route and needed 3 more in the Corbin, KY yard. Using parts
that have worked for many previous bridges, I created one and when I
generate the files for MSTS/ORTS all I get is a few parts of the original
parts, usually just the handrails to show in either TSRE, MSTS, or ORTS.
Anyone else see this phenomena, and if so, what corrected it.

Now remember, I used parts that worked successfully, many previous
