After that comes March to Spalding. When I was a student in York there was a regular service from Doncaster to Cambridge and I once used it to have an afternoon in Ely.
March to Spalding was closed in 1982 and all freight workings were diverted via Peterborough.
It was an expensive line to operate because of all the level crossings in the flat Fenland landscape. The photograph above, taken from Geograph, shows the signal box that controlled one of them being reclaimed by nature.
There is some chatter on the net about reopening it, but I don't know how well founded it is. The line from March to Wisbech looks a more likely candidate.
