The Stony Point rail line is closed indefinitely following a series of safety breaches in which boom gates failed to drop for an approaching train.

Metro cannot give a date on when the line will re-open.

The most recent level crossing failure happened last week in Tyabb, south of Melbourne.

It was the second failure this month and the last straw for rail operator Metro, which closed the line indefinitely on Monday to avoid the risk of a collision.
