I’m currently building a Minories layout with Peco Streamline and medium radius electro frog points. It was wired for DC including isolated sections at the end of the three roads, and traditional Peco point switches.
Two wires, indeed, lead from the (Gaugemaster) controller to power the track; the AC from same controller powers the points of one board, a separate Gaugemaster AC transformer powering the uncouplers on the second.
Running with the Gaugemaster wasnt satisfactory, thus a separate controller - also DC (AC fed) - recommended by another British guy on a North American forum, was purchased (Black Cat?). It gives excellent running, especially with the mechanisms of older models, as the guy suggested.
However, I’d unintentionally purchased a DCC ready loco sometime ago, which prompted me to buy a Bachmann DCC controller (offered at a very reasonable price) to power it: some day, which never seemed to come.
Thus, having wired up the layout I bit the bullet and went for it (DCC), and with the help of a couple of benevolent forum members, it was soon up and running, and using the same wiring again, using only two wires.
I wrote in my thread, that I shall never look back. It really is that good!
I’ve no intentions of adopting an all singing, all dancing, fully computerised system: I like flicking switches, thus the method of point changing, and eventually signalling will remain in the Stone Age
However, control of the trains will be forever more DCC at Monks, which requires no additional wiring to that of conventional DC as I’ve found, and with just its two wires.
