I had to cut in a crossover on my layout. The whole layout had been designed using Atlas’ RTS program, version 8.0. It has a “Crossover/Ladder” function under “Special” on the menu. I measured the distance between the tracks (measure twice, cut once), and the filler track that the program calculated was about 3" too long. Using RTS, it calculated the filler track at 7.9" long. I preassembled the crossover on my bench (usually easier than doing it in place). Imagine my displeasure when I went to test fit it on the layout. [banghead] Crossoverinformation:
2 Atlas #6 Customline left hand turnouts.
Distance between tracks 3.34" (measured between C/L’s)
Does anyone have that version, or another program that can create the crossover to see what they come up with?
With all due respect for the whoop-te-doo CAD programs, the only way to be SURE that trackwork will fit is to test/pre-assemble in place, using the components you expect to put down in final assembly.
Once you measure the parts and locate the necessary rail cuts in real life you can proceed to preassemble a crossover you KNOW will fit.
I think Chuck hit the nail on the head. With the various lengths given, I would end up with an “S” curve in the middle of the filler track, something that I’d rather avoid. With the length at 4.25", actually, I think it was 4.125", it was a straight shot from diverging route to diverging route. Anyway, I got the pieces cut, the power feeders to the frogs and I’m ready for the next step; dropping the assembly into place. Will post pics when done.
