I can't help with any of the electronics questions but would like to make an observation on the general fiddle yard plan. You say that it is 6ft long. Now peco's smallest (2ft radius) point is just over 7" long and you will need nearly the same on the adjoining track for a train not to foul the adjacent line. This means over a foot at each end, so you end up with a siding less than 4ft long. This isn't too bad but if you want to do the same again and have another siding that will use up another 6 or 7 inches each end. Ladders of points use up an aweful lot of space.

I'm sorry if this sounds very off-putting but it's best you realise it now. Try lining up some points or point plans to confirm what I'm saying. I suppose if the shortest sidings are only for DMU's and the next for another fairly short train then it won't matter too much.

I hope that you work out some way of doing it, Robert.

Sorry to post again so quickly.

Have I misread things and you are going to turn 180 degrees on this board? If so, your outside radius can only be about 20" so you won't be able to get many loops inside that, especially if you are using double track entry and exit.
