Well, you'd have thought I'd have spotted that there was a short circuit way before I got to wiring up the turntable - HND Electrical & Electronic Engineering pah!
Of course having the two entries to the turntable and the desk permanently live means a dead short when you align it to one or the other entry roads. Something had to be done, I thought about insulated joints etc but decided to remove the problem altogether by making the longer curved entry into a siding and removing the RHD point leading to it. New plan is like this:
and it looks like this in reality
Wish I'd spotted it before I bought that extra RHD point, cost me £6.50!
Wiring is almost complete, just got the station area left hand side to do, should be done in another evening, then I can get on with the Boxfile for a bit
wiring complete last night, my Hornby APT-P did an inaugural run, complete with buffet car
