Passengers are being warned of major disruption this weekend on the East Coast mainline to London.
No trains will be running out of King's Cross because of work to upgrade the line.
People are being advised not to travel to or from London from 29 February to 1 March.
The East Coast mainline serves:
- St Neots
- Welwyn North
- Welwyn Garden City
Over £1 billion is being spent on the upgrade, which aims to speed up journeys and make them more reliable.
On 29th February and 1st March, rail replacement services will be in place for "passengers where travel is unavoidable".
There will also be no trains running in or out of King's Cross on the 20th and 21st June, because of the upgrade.
When the work is finished, there should be 10,000 extra seats per day.
- Why does the work on King's Cross station need to be done?
Although the station was modernised in 2012, the existing track and signalling layout have not been improved since it was installed over 40 years ago. It's being upgraded to meet future passenger demands - passenger numbers are expected to increase by 30% by 2023.
- Which operators will be affected?
All operators on the East Coast Mainline will be impacted by the works on King's Cross.
- Can I still travel to London on 29th February and 1st March?
Yes, however, it's being advised that passengers plan ahead to avoid routes involving King's Cross. Rail replacement services will be in place on both of these days.
