Toy train operating and collecting

Rob, sounds very interesting. Please tell me more.

Many, many thanks for all your help and expertise!

 There isn't much to tell, just use up to 10 PM-1's on different blocks/power districts on your layout.  Use fiber pins to denote the blocks.

TR-1(Track One)  might be your main line level trackage.  TR-2 could be your uphill portion, & TR-3 the downhill portion.  At block transitions(when roller pickups bridge the fiber pins), whichever PM-1 is set to the higher voltage will "override" the lower set one instead of producing a short, which happens in the secondary windings on a multi-tap transformer if wired in this fashion.

What is the differance between the SC-1 and SC-2 switch controllers? Can I use a SC-1 since I only have a couple of switches that I will need to control?

 The SC-2 has a much higher current switching capacity for use with a wider range of accessories.  Check the manuals at Lionel.com for the specifics, otherwise they are very similar operationally.
