rtraincollector posted:Pictures would help as all I can find is a modern in its box and I don't see a lower cross member on that one. Another idea thou is there a way to raise the tracks coming to it so you could raise the bridge and all by how much clearance you need, or wire them to lift when your train is going under them. Would have to wire a stop for any train that might be coming to the bridge also.
I would tend to think the O.P. issue with the bridge is crossing the span and not going underneath for clearance.
With that said, I too would need to see a picture of which crossmember and it's location on the bridge. If it's in the tower, it could be ok but if it's in the center span that raises and lowered it may NOT be ok as you might compromise with the strength/rigidity of that center span and it's ability to raise and lower smoothly.
