It's definitely in public interest to eliminate level crossings even in rural areas because, if the railway is obstructed, millions of people will be cut off from their jobs and societies!
There are about 6,200 level crossings in the UK, many of which would require the closure of a road and associated knockons to emergency services.
I live a few miles from the market town of Nantwich which has four vehicular crossings and one foot crossing
Nantwich CP has just two crossings - both public vehicle crossings (full barrier at station and half barrier at Shrewbridge Road). The Newcastle Road crossing is in Stapeley. If you include neighbouring parishes, from the Bypass to the canal - a distance of under 2.5 miles, you're looking at 9 crossings - about one every 400 metres.
Public footpath: 5
Public bridleway + farm crossing: 1
Half barrier vehicle: 2
Full barrier vehicle: 1
I have a feeling there is a pedestrian signal at at least one of the two footpath Stapeley crossings (Cronkinsons?)
There were plans to close Fields Farm crossing - the farmer has been selling land recently to build a large housing estate, and has outline plans to replace what's left of the farm with 20 more houses. Network rail comments recommend that the public footpath be diverted from the current pedestrian crossing to an existing under-line crossing.
However that outline was in 2019 and nothing has progressed.
