I commute on the train from Bedford down to London - thought a few bits of info might be helpful.
Trains between London and Bedford - there are 2 main services connecting the two.
- East Midland Rail runs fast trains from St Pancras (a main London station via Luton Airport to Bedford) - the "Luton Airport Express". These take about 40 minutes and stop only twice (Luton Airport and Luton) between Bedford and London before carrying on up to Corby. They leave every half hour and have 8 carriages and are typically fairly quiet from London to Bedford in the morning (commuters go in the opposite direction). East Midlands Rail also run intercities that don't stop in Bedford, but used to. They will probably start stopping again when East-West Rail is running (see next section) - this can cut travel time from London to Bedford to just over 30 minutes. However, they stop at the main Bedford station and are unlikely to stop at the new Wixams station (which will be very close to the proposed site, see below) which will be on the slow line (used by Thameslink), but that could change I suppose.
- Thameslink run services between the South Coast, via London, up to Bedford. It's a surprisingly good service - 4-6 trains an hour, taking between 50 minutes and 1 hour 5 minutes from St Pancras depending on whether it is a stopping train or not. They all via Luton Airport. Usefully, they go ALL the way through London meaning you can join the trains up to Bedford from Farringdon (brilliant interchange with Elizabeth line which takes you to Heathrow Airport) including stops at London Bridge and Gatwick Airport. These are modern trains, up to 12 carriages long (i.e. can carry massive numbers), and again tend to carry commuters so will be emptier in the morning out of London and the in the evening into London. Thameslink trains will be the ones that stop at the new Wixhams station.
East West Rail:
- This is a new train line called "East West Rail" that replaces the old "Varsity line" which used to run between Oxford and Cambridge via Bedford. That got decommissioned last century. The connection from Oxford to Bedford will be opening in the next few years (pre Univeral GB) and will travel via Kempston Hardwick station (the one that is essentially on the proposed site). A few years later (early 2030s, the Bedford-Cambridge link will open which means tourists can do Universal, Oxford, Cambridge on a single train line - the total journey time from Oxford to Cambridge via Universal/Bedford will be less than 2 hours.
Train stations serving the proposed site:
- Kempston Hardwick: This will be a stop on the new East West Rail when it opens in the next few years. There is a consultation at the moment about station upgrades. I'd imagine Kempston Hardwick will get a sizeable upgrade.
- Wixams. This station has been stuck in development hell for a decade - it was meant to be part of the new town (stroke Beford suburb) of Wixams but central funding was pulled, and people who bought homes in Wixams on the promise of a new station felt betrayed. The previous mayor pushed it forwards last year so it is now well advanced in planning. It will probably open in 2-3 years. The location of the station is here - I can't emphasize just how close to the proposed site it is. Essentially it is separated by a thin ribbon of trees/ and a road:View attachment 20308
The current plans are for the station not to be accessed from the road on the Universal side of the station, i.e. it is designed to be accessed from Meadow Road on the Wixams side only (current plans). My guess is that, should Universal go ahead, they would make it accessible from Manor Road (B530) so you can directly walk into the park from the Wixams station via a bridge over B530 from the new station.
All in all, that means the proposed site is ridiculously well connected by train - could be <45 minutes from London if Thamesline laid on a St Pancras - Luton Airport - Wixams - Bedford service, less than an hour each from Oxford and Cambridge on the East West Line.
I haven't even mentioned the roads - it's dual carriageway connected (A421) to the M1 and A1 (two major north-south routes) with a new stretch of A421 opening that will connect it via Cambridge by dual carriageway all the way through to the East coast. All in all, great location transportation wise. I'd imagine they'd want a dedicated junction off the A421.
