The layout is 12 by 14 ft, 3 big loops, 4ea 8 ft sidings, and a yard with say 20 feet of track if you stretched it out. 21 switches, all FasTrack.

I disconnected the base and the layout itself measures 0.0022uF. Not so much.

Seems like most of the hooked up capacitance was the output of the base.
