I would not stepper but use an LM555 and a simple servo motor for the gate.
use  the switch points activated by the train points to raise and lower the gate.

A servo only moves as far  ( angle ) as the 555 timing no more no less
a perfect gate...

Many options for the discrete control of stepper motors here
