West London is projected to see population growth of over 400,000 and a quarter of a million jobs by the 2040s. If growth on this scale is to be delivered sustainably, it must be supported by the physical, social, digital and green infrastructure needed to ensure the people living, working, visiting and studying here have an excellent quality of life and it provides a place to do business fit for the 21st century economy.

There is also an urgent need to tackle existing problems of congestion, poor accessibility (particularly orbital transport links), energy resilience and access to digital infrastructure meeting modern standards. Delays on West London's main orbital roads alone costs users £80 million every year.

Through the WLA, West London boroughs are identifying infrastructure priorities and working together to make sure a robust and convincing case is made for investment. This involves lobbying national government and agencies, the Mayor and Transport for London to ensure West London priorities are identified in their investment programmes and strategies. It also involves looking at more locally-based options for delivering priorities.

West London Orbital

A key priority is delivery of the West London Orbital (WLO) railway line which will link West Hampstead and Hendon to Hounslow, with stations at Brent Cross, Neasden, Harlesden, Old Oak, Acton and Brentford. It will link major development opportunities at Brent Cross/Cricklewood, Staples Corner, Neasden, Old Oak/Park Royal and the Great West Corridor.

It will support delivery of an additional 9,000-30,000 new homes and 419,000 square metres of workspace, enough to accommodate 22,000 new jobs. It will relieve congestion on existing transport networks and provide much-needed connections between places that generate major demands for public transport. Initial feasibility reports on the project commissioned by the WLA are available here:

The Mayor's Transport Strategy included a proposal that Transport for London would work with the WLA boroughs and Network Rail to work towards delivery of the WLO. At the moment the project partners are working to produce a business case; this will set out the strategic justification for the project, an assessment of technical deliverability, its cost and potential funding options. It is expected that this stage will end in spring 2019.

The next stage will develop the project further, to establish its feasibility. The WLA will focus its attention on strengthening the strategic case and fleshing out funding options.

It is currently envisaged that WLO services will start running in the late 2020s.

Strategic Infrastructure Delivery Plan

The WLA has commissioned a Strategic Infrastructure Delivery Plan (SIDP). This will identify and cost the physical, social, green and digital infrastructure West London will need if it is to keep pace with population and employment growth into the 2030s. It will examine the scope for innovative ways of funding and delivering infrastructure and identify potential barriers which boroughs and other can work with others to overcome.

The SIDP will cover infrastructure including transport, energy, water, information/communications technology, social infrastructure (including education, health, emergency services and leisure), and green infrastructure (such as parks and open spaces).

The final SIDP will include a project schedule identifying where and when the identified infrastructure priorities will be delivered and an Infrastructure Delivery Map, which it is intended will be published on this website.

The SIDP will be published in late 2019.
