London Mayor Sadiq Khan is expected to call on the Government to invest in the planned West London Orbital.

The new Overground route would make use of existing track that runs from West Hampstead and Hendon towards Hounslow.

In a speech at the London Transport Museum’s annual dinner at Guildhall tonight (October 2), Khan is expected to pledge that he will lobby Labour ministers for investment in new transport projects.

This includes the West London Orbital, which is expected to cost £273 million in 2017/18 prices.

Its final route is yet to be revealed, but current plans would see trains stop in Cricklewood, Neasden, Harlesden, Acton, Brentford and Isleworth, and at 15 stations in total.

In some instances, existing platforms will be used but new stations would be required at Neasden, Harlesden, Old Oak Common and Lionel Road.

Last year, councillors responsible for transport in Brent and Barnet said that work on the trainline is “progressing well”, with completion expected by the early 2030s.

In tonight's speech, the London Mayor is also expected to highlight his desire to secure funding to extend the Bakerloo Tube line from Elephant & Castle to Lewisham.

A Transport for London document published in February stated that the estimated cost of the project would be between £5 billion and £8 billion.

An extension of the Docklands Light Railway from Gallions Reach to Thamesmead will also be one of Khan’s asks, according to reports.

This has previously been estimated to cost around £1.7 billion.

It comes just days after a Sunday Times report suggested that Chancellor Rachel Reeves will sign off on the HS2 Euston station in her Autumn budget.

During his speech, Sadiq Khan is expected to say it is “looking increasingly positive” that the multi-billion pound railway will terminate in the city centre, rather than at Old Oak Common.

He will also reportedly attempt to secure a long-term funding package for TfL, after the previous Conservative government only issued short-term deals.

He will then attend the opening of Siemens’ new train factory in Goole, East Yorkshire tomorrow, where most of London Underground’s new Piccadilly line trains will be assembled.
