That's some nice looking trackwork. Whose truss bridge is that? It looks like the Plastruct bridges that I bought which I'm going to turn upside down. I chose not to use solvent based paint since the basement is not well-ventilated and the smell gets into the house and is not appreciated by my supportive spouse.
Yes, that is a Plastruct bridge. I had to replace two of the Lionel truss bridges there when I discovered they would not clear a double stack car (the hard way!)
