Thanks to everyone for the replies. I will remove the capacitors, I have just ordered a pack of the point clips so will get them installed once they arrive, I still need 1 RH point to finish off the far right siding anyway. I will see how it goes in regards to running on the as is power connections if I do get stalling/jerky movement, would it be 2 seperate bus wires, onefor inner and 1 for outer & would they need to be complete ovals or do I put a break in them and work it so the controller is in the middle of each wire length?
I do need to order 2 decoders to convert current locos the lad has. A little Hornby 0-4-0 and the original Hornby HST.
