Ross Standard Gauge switches have been discussed many times here on the forum, do a search and read some of the older threads. The Ross does not come in 42" regular diameter like the original Lionel and newer MTH switches do (of course everyone should be contacting Ross and asking them to make them). But they do come in a wide radius 72" diameter version. This is by far the best SG switch ever made. You can get some ideas on how to build a simple railway using different diameter curved tracks in this thread:

The Ross does use a DC powered LGB switch machine and some think this is the end of the world... I do not. I like the low-profile of the machine plus the power for the throws is plenty and throws are crisp. The switch utilizes tinplate rail (which they get from USA Track) with a movable frog design. This ensures that the train never transverses a gap in the rail.
Hope this helps,
