Stone Crossing, just E of Dartford. My wife and I stayed three nights in the Travelodge just N of the line here a few years back, and used the station quite a few times. The road gates appear permanently closed, with wicket gates for pedestrians, if somebody with local knowledge could confirm?
However, one evening we walked down Church Hill from a local pub after 2200 and found the wicket gate also locked and the keeper's hut unmanned, which suggested it was not just locked for a forthcoming train. It would have been possible to cross illegally via the platform ramps, but as an active rail staff member I obviously did not think this was a good idea. A bridge was visible further E, and a quick check of Google Maps showed a route through a housing estate that took us over the pedestrian bridge which actually came out quite close to the hotel.
There was no notice suggesting the crossing was closed overnight, so is was this the usual situation here?
EDIT - I've just looked at Google Streetview from the N side and realise the whole site has been rebuilt with a footbridge - apologies. The view from the S side dates from 2012, roughly when we visited!
