You were correct about track projecting too far from the outside edge. Interestingly, there were TWO faulty rails exactly opposite each other. I gently nipped them with my xuron rail cutter and filed smooth.Turntable works well and stops accurately at each rail station.
I have not added the 15ohm resistors yet.
I neede to get this unit operational because of my audience's demands. Many children ,at train shows, would look at me in dismay when I said "I don't have the round house and turntable hooked up for the show". You could just here them-with there eyes and actions- muttering " Why,not?,,what's wrong with that guy?"
Thank you very much for all your advice and help.

(blue) wire with the green plug already has a 15 ohm resistor in it inside the
control box. You could try adding more resistance, perhaps another 15 ohms, by
fitting a suitable resistor with a little plug at one end and a socket at the
other, and then connecting it between the green plug and green socket.

is engaging with either end of the rotor. My guess is that one of the short
track pieces round the well is faulty: it will be the piece at one or the other
end of the rotor where it stops. Check each of these pieces. Is it not fully
home? Has one of its rails moved slightly inwards? Is there a bit of flash on
the plastic moulding? The obstruction will be catching on one or other of the
four metal wipers on the rotor: there is one wiper at each end of each rail.
These wipers are very fragile. If one is broken off, the turntable needs radical
redesign to make it useable, so be very careful.
Hope this helps. Jeremy.
