Wiring head shunts
« on: February 10, 2020, 04:06:38 PM »
I am helping a mate build a layout ,  end to end that has two main tracks, several sidings and three head shunts, we are using two controllers, on DC analogue. Power feeds and insulfrog points all work fine but have had conflicting advice regards the head shunts, currently we have power feeds connected to on off switches at each head shunt and nothing happens, my Question is Are the switches required , or is it just the case that we only need the  power feeds ,thanks in advance

You can't really answer wiring questions without a diagram showing the track, the power feeds and any insulated rail joiners.  And add in the "two controllers", I'd like to know how those are connected (there are at least three general ways of doing it).     Otherwise, what I guess you are doing is likely to be different to what you are actually doing. 

As for switches, they are usually used for one of two purposes: a) to isolate locos parked in a location, or b ) to switch between different controllers for a section of track.

With two controllers in play,  I would divide the trackwork into appropriate sections including the headshunts and wire for Cab Control so that a controller can take over any track section(s) relevant to the desired movement,  but as Nigel says we could do with an annotated diagram in order to advise what feeds and where.
