Throughout my main line I’ve put insulating joiners on both the straight through and diverging routes at the frog end of all turnouts (which are all Peco electro-frog) and used feeder wires to power both the diverging route and the following straight-through route. Doing this means I never have to worry about shorts, or which route is powered by the way the turnout is thrown.
I’m now about to lay the yard ladder. If I follow my usual method I’ll be connecting feeder wires to the base of every turnout. I wonder whether an alternative would be to feed power to the base of the first turnout only, and use insulating joiners and feeder wires only to the diverging route of each turnout? My logic tells me that if I do this all the straight throughs will be powered from that first turnout, and all the diverging routes from their own feeder wires.
