The original points (switches) were powered, and operated by an old (27 mHz) TE. With the new Revolution TE, expansion of the railway etc, I have decided to document how point control is managed.
I have two Revo Switch Controls in the garage, powered off an Amazon 18 v DC supply, and also of the same supply an output to a manual control box:
The wires are routed though junction boxes and conduit to the railway:
These eventually terminate in an IP66 junction box:
From here they are routed to the various switch drives, and the electric uncoupler when I get around to fitting it.
Finally for the Shed area, as I considered I would be closed by if operating a loco in this area, I decided to use DPDT centre of none latching switches:

Although this is also an IP66 enclosure, with waterproof switch covers, I don't trust them, so, also to hide the enclosure it will be fitted inside a signal box (when it arrives)
