I don't know about the crossing where the girls were killed, but the Ingatestone crossing had clear sight lines of at least a kilometre in each direction. It was a gentle bend on an embankment which did not have significant vegetation.

when it was closed it was clear that nobody ever really understood what the problem was, cos the issue of sight lines was the least likely.

When I shot the pictures of the steam engine Oliver Cromwell a few years back, that was taken at a crossing about 4 miles further on which has far worse sightlines from the west side, yet afaik it's still open


keep to the Fen Causeway
