Thanks for the welcome messages.
Very nice. What about the wiring?
Dead simple, San Fernandez is on a DPDT on/off/on switch, replicating this on the others is on the to do list but until then they are connected via two-pin plugs. These can be reversed when the deck is swivelled or left unplugged to isolate the turntable. The wires are threaded through holes in the pivots and have sufficient play in them to absorb several turns in the same direction but I try to alternate between clockwise and anti clockwise so they don't get too twisted.
The loco shed tracks at Grande are wired via on/off switches in a fairly conventional manner but the shed at Cuarto has its connections via a crocodile clip on a lead that can be attached to either track using a couple of pins at the baseboard edge. Similar crocodile clip/wander lead connections are used to power/isolate the main and loop tracks in the station at San Fernandez.
The wiring at Cuarto used to allow for two trains in the station but I connected something wrongly when I moved the terminus to do away with two duck-unders at doorways. The sidings can still be switched but the loop and main are a single section. TBPH this is not an issue because the timetable never calls for two trains at once.
There are three controllers (Grande, San Fernandez and Cuarto/Derrotado) so, in theory, there could be three operators on the layout but it is usually run single handedly apart from monthly operating sessions when a friend visits to play with the trains.
