I've got a boat load of Super-0... and, LOVE IT! But, I've changed my modeling and have gone to Atlas. I have about 90 straights 65 Curves, 8 or 9 112 switches (the key is the hole in the under plate that allows you to tighten (tap) the frog). Use Constant Voltage with these and put a short straight on the turnout and these switches perform very, very well. I think I'll inventory it today.
As far as issues... here are a couple of videos (part 1 & part 2) that address function/testing/maintenance of the 112 (*all* switches have issues... Lionel, Atlas, Ross etc...) it's knowing how to deal with them.

Has anyone ever tried hooking up a Tortoise to the 112?
