Network Rail Lines Up £650m East West Rail Extension Without New Tender

Network Rail is preparing to hand its East West Rail alliance £650m of extra work — no fresh competition required. The decision lines up Laing O'Rourke, VolkerRail and AtkinsRéalis to design and build a major capacity package stretching across the Marston Vale Line and beyond.

The money is aimed at one pressing problem: handling demand from the planned Universal theme park near Bedford, which is targeting a 2031 opening. Network Rail wants capacity improvements in place progressively from the early 2030s.

What does the £650m buy?

The proposed deal covers upgrades between Bletchley and Stewartby, the Oxford Parkway to Bletchley route, and work at Milton Keynes Central station. The major physical changes include:

• Double tracking between Bletchley and Fenny Stratford
• A new track layout at Stewartby
• Passing loops, electrification and re-signalling
• Station works at Winslow, Bletchley and Stewartby
• Level crossing closures, bridge and underpass works, drainage and earthworks

The package builds on preparatory work already under way between Bletchley and Bedford. That earlier programme includes replacing Saxon Street bridge in Bletchley, building a road bridge at Marston Road in Lidlington and a footbridge at Woburn Road, and closing eight level crossings.

Why no new tender?

Network Rail's argument is blunt: bringing in another contractor would create major interface risks, duplicate design and assurance work, and risk abortive construction. The alliance's track, signalling and station designs are already integrated with the work in progress.

The operator warns that separating existing track restoration from the planned double tracking towards Fenny Stratford could force the same work to be done twice. Splitting signalling responsibilities could also require unnecessary temporary arrangements.

A decade-old partnership grows

The alliance isn't new to this railway. Network Rail originally appointed it in December 2015 to design and build East West Rail's western Phase 2 scheme, starting with the development of the outline design and construction programme. This latest package takes the partnership into wider capacity upgrades.

The deal has an estimated ceiling of £650m excluding VAT, and it still hinges on funding and the necessary approvals. Not everything is bundled in: several final station arrangements in the Marston Vale signalling area and an optional train maintenance depot on the Oxford to Bletchley route are excluded and will be procured separately.

If the approvals land, the alliance will carry a railway transformation that's timed, almost to the year, with the arrival of Universal's resort — and the passenger surge Network Rail expects to follow it.
