The crossing is owned and maintained by Network Rail, so lets not bash the Heritage Railway.
The crossing is operated by the Driver or a member of the train crew who has a clear view of the crossing - the crossing control units are within 25M of the crossing. The crossing is a push and hold operation, not one shot, so the risk of hitting a pedestrian is minimised. A motorised mobillity scooter was hit a few years ago who decided that they would approach from the eastern side............... The pedestrians at present are warned by an audible warning, supplemented by visual indiactors (AKA Wigwags) on the western side.
The crossing is (was) up for renewal in 2010 (mmm it is now 2015 but we are talking Network Rail and still no sign of renewal), where pedestrian signals are proposed to be provided on the eastern side of the crossing. We wait with eager anticipation
