I'm in the midst of assembling a WALTHERS double-track truss bridge, but the peices are so warped, I've decided to give up and get a new one. I've been looking at the KATo bridge, as I've heard good things about it. But the only problem is, the track is in it already. So, is it easy to remove? If so, how do I do it? If not, then how would I join it to Code 80 flex-track, in N scale?
