IanVisits: "New railway line for West London proposed"

(it would interchange at Neasden, not Dollis Hill)

An old railway line currently used for cargo trains could be converted into passenger use, linking parts of West London currently poorly served by rail services.

The little-used railway line runs from just north of Cricklewood on the Thameslink line and loops around West London, ever so slightly just missing aligning with a number of stations on existing lines, until it join up with the London Overground at Acton.

"... A consortium of local councils, the West London Economic Prosperity Board has now endorsed a plan to convert the freight railway tracks into passenger services and create what could be an extension of the London Overground service."
