Bakerloo Line Upgrade Stage 1 Infrastructure Works
- Transport for London
Procurement identifier (OCID): ocds-h6vhtk-051c29
Description
The Bakerloo Line runs through London from Harrow & Wealdstone, in the North, to Elephant & Castle in the centre with plans to extend South as part of the Bakerloo Line Extension initiative. The Bakerloo line fleet (72 Tube Stock) is now the oldest rolling stock operating in the UK with considerable costs to life-extend the fleet and significant risks to reduction in reliability. TfL therefore intends to introduce the new rolling stock onto the Bakerloo Line. The BLU Stage 1 Infrastructure works are required modify and upgrading the line's infrastructure to enable the introduction of the new rolling stock with the works expected to completed by, circa 2034. The core elements of the scope include:
• Reconstructing Stonebridge Park Depot to consolidate all maintenance activities.
• Expanding Queen's Park Area to deliver additional stabling capacity.
• Modifying London Road Sidings to retain and minimally adapt existing facilities for continued stabling usage, as well as introducing a Driver's Training Facility.
• Waysides works to ensure the line's power supply, signalling systems and potentially gauging is compliant with the new rolling stock.
This is a refinement of the scope presented during TfL's previous 2024 BLU Early Market Engagement with the current scope having moved the cleaning shed from London Road to Stonebridge Park and no longer required the cleaning shed at the front end of the programme. .
