Paragraph 48 Conditions and Requirements to be observed by the Society when the Road is Open to the Public.

In the event of a failure of both intermittent red lights in any of the road traffic signals, provided the barriers have not commenced to lower they will remain in the fully raised position and the signals on each railway approach will continue to show an intermittent red light. Should such a failure occur with the barriers in any position other than fully raised they will lower and remain lowered until they are raised by the passage of a train or locally/manually. In these circumstances the white signal on the relevant railway approach will be extinguished and the other signal on the same railway approach will show an intermittent red light.
