Thameslink, which connects the north and south of the London river, will face ‘major disruption’ today.
The railway company announced on X that ‘urgent tunnel repairs’ are taking place between Blackfriars and London St Pancras.
Engineers will likely be carrying out repairs for the next few hours, Thameslink said, with services delayed or cancelled until 3pm.
‘Our Sunday service normally starts from 09:00 through the core,’ Thameslink said, referring to St Pancras and Blackfriars.
‘However, due to the inspections and repairs required, we are expecting both lines to be blocked until at least 3pm today.’
National Rail, which represents train services, said the tunnel at Farringdon has been closed for ‘safety reasons’.
Are Thameslink trains delayed or cancelled today?
As the ‘core’ of the line is closed, a lot of trains are being diverted, delayed or cancelled.
Trains that normally run between Cambridge and Brighton will terminate and restart at King’s Cross.
The route between Bedford and St Pancras will be reduced to just two trains an hour.

‘Your tickets will be accepted at no extra cost on Southeastern services between London and Plumstead,’ the operator said.
Some stations will have no Thameslink trains trundling through them at all:
- Loughborough Junction.
Thameslink warned in an update that commuters might have to switch to different train operators.
But paper rail tickets, as well as London Underground trips between the closed stations, as well as Elizabeth line trains between Farringdon and Abbey Wood, will be accepted.
Some bus trips will also be covered by Thameslink ride tickets.
