Wow! I just noticed we are on page 50!! Thank you everyone who has contributed.
Bob, here is the 1/4” plywood. It is old and brittle on the outside layers. The inside layer shows up here.
Maybe it needs more layers to stiffen it or it lost something with age.
Friday evening I screwed down all the track except the straight section that I have the metal base from the destroyed Menards bridge as a base. I need to cut it to length and am thinking of using the sides of the two through girder bridges over the street running away from the viewer. Another option I thought of is using the two girder bridges as is with a pier in the middle and have one traffic lane on either side of the pier. I either need another pier or use the long piece of metal to span the gap.
Here are a couple shots of a train on the upper level with a different building arrangement. That is the heaviest engine I have, and the track didn't give at all.
