I wonder what is causing this? What powers the train? Is either the train
or the track electrical?

I'd be interested to know what sort of unusual audio-frequency electrical
signals you might be able to pickup from a passing train. Perhaps a guitar
pickup or something similar would give you an audio signal from the train?
If the train produces a field that shakes your monitor, it might possible
to record it this way.
