As noted, the train only draws a couple of amps, so it's not a high load issue.

I guess that is exactly my point, if a 10% load pulls the transformer voltage down 20% there may be more to the issue than meets the eye!
In an attempt to understand this, I would put a fixed load of a few amps on the transformer, maybe some incandescent lights or something, reset the voltage to 20 and try to run the loco again with the fixed load still connected. I am guessing that the voltage soars at no-load, rather than dipping at light load. In that case running a small load continuously might be all you need to do.
I would also be sure I was measuring the voltage with a good voltmeter. Be a shame if you went through a lot of trouble and learned that it was a measurement anomaly.
