Published on Wednesday 30 September. This is a developing story — disruption details are changing through the morning. Check before you travel.
Major disruption is affecting several Tube lines this morning, with the Metropolitan and Piccadilly lines part suspended and severe delays on the Victoria line.
The Metropolitan line is suspended between Aldgate and Uxbridge because of a signalling problem at Rayners Lane and a fire alert in the Kilburn area. The Piccadilly line has no service between South Harrow and Uxbridge, also because of the signalling problem at Rayners Lane.
Meanwhile, the Victoria line is suffering severe delays across the whole network, and the District line has minor delays between Upminster and Earl’s Court westbound. No reasons have been given for the Victoria or District delays.
Commuters heading into central London for the Wednesday morning rush hour are being told to plan their journeys and expect delays.
Why one fault hits two lines
West London commuters may be wondering how a single signalling problem can take down two Underground lines at once. The answer lies at Rayners Lane, where the Metropolitan and Piccadilly lines share the same stretch of track on their way out towards Uxbridge.
That shared section is the only part of the Piccadilly line that runs west of South Harrow, so a signalling failure there wipes out the Piccadilly’s western end entirely. The Metropolitan line is hit harder still: suspended between Aldgate and Uxbridge, that covers the line’s full core route through the morning, on top of the separate fire alert affecting the Kilburn area.
Shared-track sections like this are a known weak point in the network. When the signals fail at a junction both lines depend on, there is no way to route around the problem — both services simply stop.
What to do if your line is affected
If you normally take the Metropolitan line from anywhere between Aldgate and Uxbridge, you will need an alternative this morning — there is effectively no Metropolitan service running on its main route. From the north-west, Chiltern Railways services and London buses may be options depending on where you are headed, and National Rail routes into Marylebone or Paddington can cover part of the journey.
Piccadilly line passengers travelling from west of South Harrow face the same problem on the western end of that line. The good news is that the Piccadilly is still running east of South Harrow, so anyone who can reach that part of the line — by bus, or by walking to a nearby station on another route — can still get into central London.
Victoria line users are in a different position: trains are running, but with severe delays across the network, so allow plenty of extra time and expect packed platforms at the busiest stations. The District line’s minor delays between Upminster and Earl’s Court westbound are less serious but still worth factoring in.
The single most useful thing any commuter can do right now is check the live status before leaving the house. TfL’s status page and app carry the latest updates, and the picture can change quickly during a signalling failure — a suspension can be lifted or extended with little warning as engineers work on the fault.
A difficult morning for London’s network
Wednesday’s disruption comes on the same day as major disruption on the London Overground after a tree fell on the tracks, making this one of the tougher mornings for the capital’s rail network in recent weeks. Earlier this month, Overground passengers faced a weekend of planned disruption, and South Tottenham station was shut by an emergency incident.
For now, the advice stands: check before you travel, allow extra time, and have a backup route in mind. This story will be updated as the situation develops through the morning.
