Perhaps off-topic but, if you are constructing a move-able layout with Scaley Sport track, keep in mind the continuity of the track will suffer over time. I had 100' of Sport track mounted on a large platform that was braced underneath, and was designed to be lifted and leaned against a wall when not in use. After a few months, I started having all sorts of intermittent power issues, even with 4 power taps. The track was clipped down, glued down and even screwed down in a few places, but there were still problems. Eventually I just tore the whole thing down, sold the plastic track and built a wood track.
Consider either using copper tape or soldering connections between track sections if you're going to be moving the track regularly.
