@Madockawando posted:Hmm... how would you do that using Fastrack?
I'm not a Fastrack user but Lionel does have insulated rail Fastrack sections. I would imagine you could also fabricate insulated rails from a standard piece of Fastrack. You would have to solder wires to the rails. The isolated rails would attached to the latching relay triggers. This eliminates dwarf signal flickering. I use the Azatrax LARY-AC: https://www.azatrax.com/latching-relay.html
