I need quit a few switches for my new RR.I'm using ME C70,and right now,I can barely find them.I need 20 just to finish the upper two track mainline,and I have three yards.Not only that,I have a pile of extra rail,and the amount of money I'd save is more than worth it.Only problem,Fast Track doesn't make a specific C70 jig.What difference is there between the codes as far as the actual jigs? Can I get away with a C55,or won't it work? I watched the video,looks like the code shouldn't be a problem,yet,C40 and C55 take different jigs..Any thoughts?
