I was playing around in SCARM creating a tiny multi route city scene using SuperStreets. When I tried to use D21 curves (and the switches) to form part of a figure 8, I found that each leg (after a curve to straight 2.5" and a 5" straight) was about an inch short of meeting up with the intersection piece in each direction. Does anyone have any suggestions with closing the gap, as it is not on a 2.5" increment. Do the adjustable length tracks work? Do they even exist? Would I be better off shortening and securing a 10" straight?
Take a straight section, cut it with a fine hobby saw and make it a permanent part of another section with adhesive, soldering jumpers for each rail.
