I never seen a train overtaken by another train in a parallel track lane. Usually there are trains bypassing opposite direction to each other from parallel track lanes.

I think it would be easy to distinguish with confidence if the passing train sound comes initially from your back or from your front.

Additionally you would be aided by the Doppler-shift effect of sound of the bypassing train that initially will increase in pitch and then lower in pitch as the two trains separate.
