I wish them well with their plans, but am unconvinced on the merit of reopening a rail link.
I won't dwell on the practical problems of reopening, but question if such a link would generate sufficient new custom to the railway to make it viable.
My comparison is with nearby King's Lynn, currently a significantly larger town than Wisbech but also the railhead for a large hinterland stretching to the North Norfolk coast, a total of 150,000 people. This hinterland is the key difference. King's Lynn has approx. 1,000,000 entries and exits a year.
Much of the sparsely populated hinterland around Wisbech is already reasonably well served by rail links at March, Peterborough, Spalding, Downham Market and King's Lynn itself. Regarding Wisbech alone, the X1 bus serving Peterborough and King's Lynn offers a viable alternative for travellers without a car.
I don't see a Wisbech reopening changing this except at the margins. So what would the viability criteria be - 300,000 entries/exits per year over and above cannibalisation of custom from existing rail links, say?
You make very valid points. I think a lot depends on what service is offered.
a) A Wisbech-March shuttle? I think this would indeed create a very marginal change.
b) Wisbech-London via Peterboro or Ely would be ideal - but won't happen. (will it?)
c) So we are left with some kind of other service or combination of services which would take some time to see a build up of traffic such as
Wisbech-Ely-Cambridge or
Wisbech-Ely-Cambridge-Stansted (perhaps the best option for limited investment, but probably no capacity at the Cambridge-Stansted section)
Wisbech-March-Peterborough (perhaps too slow to attract London travel)
Or (as I suggested some months back)
Wisbech-Ely (change for London)-Soham-(via reinstated chord)-Newmarket- Fulbourn-Cherry Hinton (new stations, some new doubling of route)-Cambridge.
This latter option would need significant additional investment, of course - but would, in effect, create and merge two, or three, new commuter routes. And allow Cambridge-Ipswich services to be accelerated (could drop the stops between Cambridge and Newmarket, except in peak hours or Sundays).
I think it would be a huge benefit to the region if implemented.
Of course, all bar the Peterboro option would also necessitate work on Ely level crossings, as mentioned.
