London is set for a new 700 million Overground line
The West London Orbital would create a new London Overground branch linking Hounslow to Hendon and West Hampstead via Old Oak Common, costing about £700m.

Old Oak Common could have been configured to extend Elizabeth line services northwest toward Watford Junction via sidings linkage to the WCML, offering diversion capacity.
