Reply to "Using Ross Track: How do I do this?"

I may be wrong, but I bet a half 072 curve would line them up close.  Then cut it to fit.  What the heck do you need a software program to figure that out?  Get the track, lay it down and make it work.  You will most likely have to cut a straight piece to fit as well.  If you are cutting a lot of track, a Dremel with a cutoff wheel you can get from Ross for cheap works the best and will last a whole layout worth of cutting.  Good luck.
