Paragraph 51 Conditions and Requirements to be observed by the Society when the Road is Open to the Public.

If the white railway signal mentioned in paragraph 31 above shows and the crossing is unobstructed, drivers of trains in both directions may drive their trains over the crossing at a speed not exceeding the speed indicated on the relevant board described in paragraph 35 until the front part of the train has passed over the crossing. If the white light does not show and the red light continues to show or the crossing is obstructed at the time the white light is showing, drivers shall bring their trains to a stand short of the crossing and may thereafter proceed with caution when it is safe to do so.
