General uses of SC-2 aux1 and aux2

Clarification: My intent is the aux2 would toggle a separate relay on and off, and that separate relay would connect power to the track in question from the track power circuit.

I use block power controllers ,BPC's, for all of my yard tracks and SC2's for switches.

Well, you can wire up to 15 amps (I'd probably stop at around 10) through the SC2 without having any other relays in the picture.  For keeping one conventional engine and train idle, I can't imagine you need more than a 10A capacity.

The .1uf capacitor was to allow DCS signals to propagate into a yard, don't know if this is a need for you, the SC2 would obviously be controlled using TMCC/Legacy.

I have used the SC2 to power sidings on and off with no problems at all. 

I'm pretty sure the BPC and SC2 use the same relay to control the power.

I use the SC2 to power sidings on and off.  I use the Aux 2 to turn the siding power on or off, and I use Aux 1 to control an uncoupling track on that same siding.  It's a bit high on the power side for the uncoupling track, but I haven't had any  problems yet.  The other nice thing, is the siding/spur and uncoupling track share the same id on the remote and it takes more full advantage of the SC2 (6 full on/off and 6 momentary on/off = potential for 6 sidings and uncoupling track, I currently have 3).

Thanks Doug, John, Jeff and JR.  For Lionel TMCC, I forgot the signal is passed through the common rails, so a center rail gap won't stop it as it would for DCS.  For trains of both persuasions, then, just a 0.1 microfarad cap to pass the DCS signal would do.  I'll look at the BPC as another track power option.

Thanks all!
