Rail passengers are facing travel chaos on a miserably wet and windy Saturday after hairline cracks were found in a number of high-speed trains.

Major services were cancelled as trains across four rail providers were being inspected by experts following discovery of cracks in Hitachi 800s.

Great Western Railway (GWR), London North Eastern Railways (LNER), Hull Trains and TransPennine Express services are experiencing "major disruption", said National Rail.

The operators warned there would be cancellations and severe delays while the cracks were investigated, with LNER urging passengers not to travel on its services on Saturday.

There is limited to no service on the East Coast, between Edinburgh, Newcastle, York and London.

All high-speed GWR services between London, Bristol, Cardiff and Penzance have been cancelled.

Passengers have been told to check online journey planners if they do decide to travel.

National Rail tweeted: "Some GWR, Hull Trains, LNER and TPE trains have been taken out of service today for safety checks as a precautionary measure.

"Once trains have been checked, they will be released back into service as soon as possible. Please check before travel."

GWR said in a statement: "Due to more trains than usual needing repairs at the same time at London Paddington fewer trains are able to run on some lines."

LNER said it's experiencing "significant disruption", adding: "We advise customers not to travel today.

"Please visit our Travel Alerts page for information on refunds and alternative travel."

A spokesperson for Hull Trains said Hitachi is investigating the issue with a number of trains taken out of service.

He said: "A number of Class 800 series Hitachi trains from several train companies have been taken out of service today for checks as a precautionary measure.

"This problem is being investigated by Hitachi and once trains have been checked, we hope to be able to release them back into service as soon as possible.

"This could affect a significant number of our services and passengers should check before they travel."

TransPennine Express said: "This will affect a significant number of services on our Newcastle to Liverpool route and we are advising customers not to travel on this route today."

Hitachi 800 trains have been in service since 2017.

They were built at a factory in Newton Aycliffe, County Durham.
