Morphology

rail + off

The meaning is directly compositional: 'rail' (to fence off/enclose) combined with the particle 'off' (indicating separation or removal) yields 'to enclose/separate by putting up a rail or barrier'. This follows a common English verb + particle pattern (e.g., 'rope off', 'section off') and would be inferable to a B1 learner who knows the constituent meanings.

Etymology

Rail off may come from the simple image of putting a rail or low fence off around a place to keep people out. By making that barrier, you separate and protect the area, so the phrase means 'to enclose or close an area with a barrier'.
