It's on a key freight route. Passengers are surely secondary.?
The timetable does not bear that out, with a large proportion of the train paths taken up by very short passenger trains. The worst offender is the Liverpool-Norwich service, which, because it reverses at Ely, takes up 4 paths every hour with a 2 car train. The Stansted-Birmingham trains are only 3 cars.
I appreciate the Ipswich-Peterborough service is fun on the map, but am curious how many travel on it across Ely... do Ipswich-folk use it to reach the ECML in meaningful numbers?
There has been at least some through services between Ipswich and Peterborough for a very long time, go back 60 years and there were trains like the Harwich-Rugby and the Colchester-Glasgow. Ipswich is a big town and, like Cambridge and Norwich, it does benefit from "one change" inter-connectivity at Peterborough with the Midlands and the North.
The main difficulty for the passenger timetable is that Ely-Peterborough only justifies 2tph (of suitable length) yet all of Norwich, Ipswich and Cambridge want 1tph to/from Peterborough, and 3 into 2 doesn't go. Portion working could solve that, but it lacks resilience. Reducing Ely-Peterborough to 2tph would free up the paths that the freight needs, without any need for extravagant engineering projects.
But any solution to this is difficult to implement because of the large number of different TOCs involved: all of Great Northern, Greater Anglia, East Midlands and Cross Country have a finger in the pie.
A bay at Ely could also turn more service, as a sop to no through journeys, and avoid a crossing to the west side.
But the only space for a bay at Ely is, er, on the west side.
What’s the usage of Soham like? I was amazed it got authorised on a busy freight line when it isn’t connected to the obvious destination.
Vanity project for James Palmer, the first Mayor of Cambridgeshire and Peterborough.
There is conveniently (for this idea) no bus service
There used to be. It was one of those cut by Stagecoach a year ago.
Cambridge to Kennett was always in the cards for double tracking
Warren Hill Tunnel at Newmarket always has been, and always will be, single track.
You won't be able to run 2tph via Newmarket without another passing loop between Dullingham and Cambridge.
Doesn't really help. The main constraint is paths around the Cambridge station area. The north end of the station is very congested at peak times because of movements in and out of the carriage sidings.
