Which parts of the UK’s rail network are going up in smoke after a power failure?

A section of the London Underground is still in chaos after a massive power failure caused by a fire at a power station.

The cause of the fire has not yet been confirmed.

The cause of Thursday’s power failure is still being investigated.

It happened on the M6 at around 9:45am.

The fire is believed to have started on the track, which runs through central London and is under a state of emergency.

The London Fire Brigade said it was at a “critical point” but the cause of that failure was still being considered.

It is understood the fire started on a section of track under the control of the South Eastern England and Northern Ireland Fire Brigade.

The area has been evacuated and a number of stations in central London are under a boil water alert.

More: A further three fires have been started since the power failure.

In all, eight fire engines and four police officers were on the scene.

The power has since been restored to the stations, but it will take some time for the fire to be put out.

The Metropolitan Police said in a statement: “Firefighters from the Fire Brigade, Ambulance Service, Transport for London and the Metropolitan Police have been at the scene and will continue to assist with the response.”

It said the area was now under a State of Emergency.
