This shim worked for CN&W late 90's issue as well.

This problem may have something to do with the non-sinusoidal waveform of the CW-80.
If there is a CW-80 setting that will work, it may give a very different reading on a voltmeter than the setting that works on a simple transformer.
The usual way of measuring AC voltages is the root-mean-square (RMS, the square-root of the average of the square) voltage. Any AC voltmeter you are likely to have will measure the correct RMS voltage only if the waveform is sinusoidal. Unfortunately, the CW80's waveform is not sinusoidal. So its voltage can be measured accurately only with a rather special voltmeter.
Here is a table that converts the voltmeter reading of a CW80 to RMS volts:
0 0 1 2.7 2 4.4 3 6 4 7.3 5 8.6 6 9.7 7 10.8 8 11.8 9 12.7 10 13.6 11 14.4 12 15.1 13 15.8 14 16.4 15 17 16 17.4 17 17.8 18 18

I received a Lionel Horse Car for Christmas (modern post-war celebration series) version from 2000 or so. Got it all wired up and it seems the same thing is happening with mine. The horses won't go up the ramp and many times fall over as they move through the corral. I have the corral hooked up to a CW 80 transformer (accessories terminal). I have set it at 11 volts. Any higher and it's just too much. My layout is with fastrack and is on carpet under the Christmas tree. I'm using the fastrack operating track. Do you know if this accessory will work on carpet? I might try to shim this on the back like you suggested. Also, it seems the horses don't move very quickly through the horse car. What track voltage is required to make the horses move through the car effectively?
I'm back!
