Morphology

rail + line

The meaning 'a set of railroad tracks forming a route for trains' is directly and compositionally derived from combining 'rail' (relating to railways) with 'line' (a route or linear formation). This noun phrase is a common, literal collocation with clear cross-linguistic equivalents (e.g. 'línea férrea', 'voie ferrée'), so a B1 learner who knows the constituents should readily understand it.

Etymology

Rail line comes from the simple image of long metal rails laid in a straight line across the ground to carry trains. So rail line today means the tracks and the ground that support them, or 'a route for trains'.
