Stone Crossing near Dartford had, until recently, a gated vehicle crossing operated by a crossing keeper. That has now closed, but the pedestrian gates are still controlled by the keeper.
Was there just two weeks ago. I think the pedestrian gate on the far side from the keeper's cabin is electro-magnetically locked by the keeper when trains are approaching. There must also be some method for alerting the keeper to pedestrians on the far side as when I approached she turned round from her panel and through the open window shouted across to inform me just one train was passing through. I didn't see any CCTV monitoring the far gate.
This crossing however isn't manned 24/7. There is quite a lengthy, poorly lit detour to cross the lines when the pedestrian crossing is closed. Network Rail have, on occasions, employed a security guard to counter trespass. They also promised the local Parish Council a footbridge in 2009. But now say policy is to only build ramped footbridges, and there isn't the space at Stone Crossing for one.
