There are major issues on the London Underground network and Elizabeth line due to power failures. The Bakerloo line, Waterloo and City line plus the Overground's Suffragette line and Weaver line are entirely suspended on Monday afternoon (May 12).
Sections of the Northern line and the Jubilee line are currently partially suspended, with the Elizabeth line also hit.
It is not known if the power outages are linked. The Elizabeth line is part suspended with no service between Paddington and Abbey Wood due to a power supply failure. Transport for London (TfL) states there is a 'good service' on the rest of the line.
On the Northern line there is no service between Morden and Stockwell and also between Euston and Kennington via Charing Cross while TfL deals with power supply failure. London Underground tickets will be accepted on London Buses via any reasonable route.
On the Jubilee line there are severe delays on the entire line and there is no service between London Bridge and Finchley Road due to a power failure. Tickets are being accepted on London Buses.
There are also issues with the whole of the Bakerloo Line hit with a power failure

TfL said they are currently working with the National Grid to determine the cause of the outage.
What has The National Grid said?
The National Grid tweeted: "We apologise for any inconvenience following a fault on our transmission network in central London this afternoon.
"The fault was resolved within seconds and did not interrupt supply from our network, but a consequent voltage dip may have briefly affected power supplies on the low voltage distribution network in the area.
"We once again apologise for any inconvenience and ongoing travel disruption."
IFS cable car closed
The cable car across the Thames has been closed as storm clouds roll in over London.
We could be in the midst of a thunderstorm at any moment, a stark break from the sunny weather.
As such, TfL has chosen to close the cable car that links the Greenwich Peninsula and the Docklands.

TfL say outage due to National Grid issue which started in South West London
A TfL spokesperson has said that the power outage was due to a "National Grid issue" after there was an outage in south-west London for “a matter of minutes” and “everything shut down”, the PA news agency reported.
The spokesperson continued: "When the power goes out the trains will have stopped, obviously, there’s emergency power on trains and stations so everything wouldn’t have gone completely black, if you were on there, but the trains would have stopped and we would have cleared some stations because there’s no electricity it might not necessarily be safe for them to be open … some people would have probably been stuck in a tunnel for a little bit of time.”
TfL is in the process of “getting things back up and running again”.
Railside fire near Tottenham Hale causes more disruption
A railside fire has blocked all lines from London Liverpool Street to Stratford and Tottenham Hale, compounding the disruption caused by the power outage on the TfL network. Trains may be cancelled or severely delayed by up to 50 minutes or revised. Disruption is expected to last until 5pm.
The following routes have been affected:
- All Greater Anglia routes to / from London Liverpool Street, and also between Stratford and Meridian Water / Hertford East / Bishops Stortford
- All London Overground routes to / from London Liverpool Street
- All Stansted Express services to / from London Liverpool Street
TfL website crashes again
TfL's status update website has crashed for a second time within 30 minutes due to massive traffic as the Bakerloo, Waterloo and City and Suffragette line remain entirely suspended and the Jubilee line and Elizabeth line are still partially suspeneded.
Northern line unsuspended
The Northern line has been unsuspended and now has minor delays across the whole line.
All other lines remain suspended as before - Bakerloo, Waterloo and City and Suffragette are entirely suspended.
Jubilee and Elizabeth remain part suspended.
TfL status website crashes
TfL's London Underground, Overground, Elizabeth line and DLR status checking website has crashed amid the power outage chaos. An error message on the web page reads: "Something went wrong? Sorry for the inconvenience. A timeout occurred. The origin web server timed out responding to this request." This is likely to the overload of delayed passengers checking what is going on with cancelled trains.
Waterloo and City line entirely suspended

Staff at Covent Garden station reported the entire Tube network down, LBC has said. It is unclear whether this is the case, however as TfL has not reported that every line has been shut down on their website.
Staff at Covent Garden station are telling customers the entire London Underground is down due to a power outage.
