There is ‘major disruption’ on trains to and from London Marylebone this morning after a fault with the signalling system.
All lines in and out of the station are blocked, causing cancellations and 90-minute delays.
It’s impacting Chiltern Railways services between Marylebone and High Wycombe, Birmingham Snow Hill, Oxford, Gerrards Cross, Aylesbury Vale Parkway, and Aylesbury.
The issue was first reported at about 6am and disruption is expected to last until about 2pm.
Meanwhile, on the Underground, the Piccadilly line is partially closed again between Rayners Lane and Uxbridge after fallen leaves caused ‘difficult track conditions’.
There are also minor delays on the Piccadilly, Jubilee and Northern lines.
