Thank you for this correction! I have edited the original post...Surely you mean "one via Sandy and one via Hitchin"? They would both start at Bedford Midland.

Would there be space for another pair of tracks to run along the eastern side of Sandy station? Instead of having a Tamworth-style cross-shaped station, the EWR line could curve around the north of Sandy and pass over the ECML before curving round to run parallel. After running past the station with a new pair of platforms, it can then curve around and head towards Shepreth, so that it would share the existing line into Cambridge at the end. This would make it similar to Nuneaton, where most traffic stays on the line it's on but it is still possible for trains to cross between them. The grade-separation of EWR and the ECML doesn't need to be perfect, as you can have trains cross the EWR tracks on the flat so long as they don't do that on the ECML. If the tracks are properly parallel through Sandy, then going between the southbound ECML and the eastbound EWR track in either direction would just involve crossing over the westbound EWR track. The switch between the northbound ECML and the westbound EWR would just require some limited extra earthworks and tracks, with the northbound ECML to EWR just needing a curve following the inside of the angle between the two lines at the EWR overbridge and the other way just needing a similar curve from the other side then curving round to rejoin the ECML.
IIRC it's one of, if not both of the sections either side of Winslow - if you look at the route on Google Earth you can see the line is otherwise almost entirely straight, but there's a couple of obvious deviations presumably due to ground conditions.
If the line runs via Sandy and has its own route from there towards Cambridge then I can't imagine there will be much need for trains to transfer between the two routes. A flat ladder junction for diversionary purposes would be good enough. Another option would be for it to join the ECML southwards towards Hitchin and then take the existing line towards Royston, which would avoid a new route eastwards from Sandy but need grade separation both there and in the Hitchin area.
An option using the ECML towards Hitchin could go round the west of Sandy, join the ECML further south and have an interchange at Biggleswade instead.
More chance of a compound working into St Pancras on a scheduled service from Manchester Central.
If you look at a map, the Midland and GN main lines converge to a point on the latitude at Bedford-Sandy at about 8 miles distance, before they immediately begin to diverge again - like the waist of a 14-year-old girl.
There is a good reason for that, namely the hills that appear immediately to the north of Bedford (and they are there, though not so immediately on the GN side).
Then you've got the section from St Neots into Cambridge - that ain't exactly plains as I remember it.
Much as it would be better for passenger numbers and connectivity, unless they choose St Neots to be a second Milton Keynes, with integrated public transport from the outset, including E-W Rail (yeah, right - more compounds into St Pancras), it would cost the earth.
No, either they revive (most of) the original route to Sandy, or they go south along the Bedford-Hitchin route - which makes a mockery of calling it East-West Rail, but still, it's somehow doable. Sorry, but going north and then east from Bedford just isn't going to happen.
EWR are only looking at Sandy and Hitchin alignments. So why the talk of going north of Bedford?
I do agree that going north of Bedford solves a lot of problems with connecting Bedford Midland to the route. The hills north of Oakley going east are very wavey indeed, its almost up and down all the way. So a major cutting operation would be required to make any railway go this route.
In this day and age things are more doable in the practical sense. But getting funding for it is another matter entirely.
You're never heard of embankments, cuttings, bridges and tunnels then?
Only mild earthworks would be required north of Bedford.
St Neots to Cambridge "not exactly plains" - sorry but do you know the area at all? St Neots to Cambridge is VERY flat. Not entirely, but it certainly is very flat indeed.
Reviving the old Sandy line would not connect with Bedford Midland and would need to be fully re-engineered as this was never a 2 track line.
You may as well build a new line and collaborate with road builders to get the optimum solution rather than make a half-baked solution which serves no-one.
As stated by "70014IronDuke", "getting E-W rail east of Bedford is not easy. And even if the entire former route from Bedford to Cambridge was intact, it was not an ideal permanent way."
I would also question the potential traffic (passenger or goods) to justify such an expensive investment. The route would have no commuter function, unlike the re-opened Scottish Borders line. Connectivity at Bletchley, Bedford and Sandy with express trains would be poor and end-to-end traffic very limited. I lived in Cambridge for 3 years and never once had the need to go to Oxford. I don't expect this line to be re-opened east of Bedford for many years, if ever.
A proposal for a Bedford-Peterborough service via Wellingborough, Kettering, Corby and Stamford, by means of a Manton curve or a short cut from Seaton to Luffenham on the former LNW Stamford branch line trackbed, is more likely to be viable.
Building the eastern section would allow existing towns to have better-paid workers commuting to Cambridge as well as London and would also make it feasible to create and expand other small towns and villages along the route.
EWR would make it quick and easy to get to Cambridge from the Thames Valley, Oxford (high-tech businesses do need to talk to other ones, remember), the Chiltern corridor, the WCML, the MML and the ECML, as well as making it feasible to further boost links going eastwards into East Anglia.
Cambridge station was deliberately sited some distance from the town centre
To get the best return on the investment the mainlines need to interchange with EWR, and in my mind that means Sandy and Hitchin are non-starters. Bedford Midland and St Neots are the only stations that will achieve what is required.

Bedford Midland and St Neots are outer suburban stations served mainly by Thameslink. Bedford Midland only has 1 northbound train per hour (a semi-fast to Nottingham) and northbound services from St Neots only go as far as Peterborough, which is simpler to reach from Cambridge by direct train or changing at Ely.
Wrong on Bedford. It has a half hourly northbound service. One to Nottingham one to Corby. It's had a half hourly northbound for a good number of years now.

i.e. Luton to Doncaster without having to drive (or take a bus) across to Stevenage then taking the train north becomes Luton-Bedford-St Neots-Doncaster by rail without having to go via Leicester or London!![]()
Luton-Bedford-St Neots-Peterborough-Doncaster involves as many changes as the existing service Luton-Bedford-Leicester-Sheffield-Doncaster and is no more direct. I don't see the benefit.
Having an interchange at Sandy is great but the station needs to move if its going to have a Tamworth "upper lower" level system.
This seems quite effective to me as you thus skirt the northern Sandy estates that have been built over the old route. Bearing in mind what others have written about the Cambridge station being not very handy for the science centres, do you have an approach route to Cambridge in mind?Yes, but I'm not advocating a Tamworth-style solution. I'm advocating a more Nuneaton-like solution where all platforms are parallel but the EWR route still does remain operationally separate from the ECML. The justification for that would be that it would then be feasible to run services between the two lines in future.
