That's a complicated question, because it depends on the nature of
the tracks and the signaling system in use on the particular
railroad.  But in general, I would agree with your doubts.  Railroad
tracks are generally grounded (at least at the frequencies we're
talking about) but not as well as a proper AM ground system (or even a
proper electrical ground system).
