Rail passengers were advised to avoid travelling on the East Coast Mainline on Wednesday as high winds swept across England.
Passengers should check travel times with National Rail Enquiries
Mainline operator National Express imposed an 80mph speed limit between Stevenage and Edinburgh due to the risk of track obstruction or power failures.
However, the company said tickets bought for Wednesday would still be valid on Thursday.
Passengers who choose to travel should expect delays.
A National Express spokesman said: "The trains have been fairly quiet today, so passengers appear to be heeding our warning to delay their journeys until tomorrow.
"The speed restriction is likely to be in place until 1700 GMT, though realistically it will have a knock-on effect for the rest of the day."
Other train services, including the Sunderland to London link operated by Grand Central, are also affected.
Passengers are being urged to check with National Rail Enquiries before travelling.
The West Coast Mainline has also been disrupted by the high winds.
A 50mph limit on the line has since been lifted, but many cancelled services will not be reinstated today.
