@mike g. posted:Stan and John, thanks for the information. so with just 2 sidings that I power on and off can I do that with one DCS box?
Yes, I manage six sidings on one TIU channel, each siding has an individual power switch, all are powered from that single channel. I also have sixteen turntable whisker tracks and my access loop for the turn table on one TIU channel, each whisker track is individually switched when I want to access the engine in that location. The sky is the limit really. Most of the channels will be off and not affecting the DCS signal as a rule.
