Is the track on the KATO double-track truss bridge easy to remove? I have a WALTHERS double-track trusss bridge am am in the middle of assembling it, but most of the peices are so warped, I've decide to just buy a new one, and I'm looking at the KATO bridge as I've heard good things about it. I'm using PECO code 80 flex-track, in N scale if that matterss.
