North End Of Fiddle Yard Electrics
I have now just about completed the under circuit wiring for the North End of the Fiddle Yard (actually it is only North by orientation of the room - on the modelled location it would be the South end) - Becuase I am so incapable of working upside down these days I made the board with track breaks at both ends so that it could be lifted up later - although the overpass track will need to be removed.
The electrics have taken a long time, as there are something like 35 different track feeds to the yard (in order to get occupancy information) as well as 14 points that each need polarity switching for electrofrog and point motors connecting up.
You don't actually have to do polarity switching as the points do it internally these days but the mechanism is not the most robust so I use prefer to do motor contolled polarity switching.
Because some occupancy sections cross the board break I have to do some cross wiring to the South side and vice versa which adds some complexity. As ever I am fighting to keep it neat.
Still at least it all seems to work.
