A shortage of train crew means a reduced service is running across Great Northern and Thameslink networks.

We anticipate disruption will continue until the end of service tomorrow.

Due to ASLEF industrial action, other operators in the area such as London North Eastern Railway, Greater Anglia and London Overground are severely disrupted with NO service on parts of their network. This means our services which are running will be extremely busy, so only travel if absolutely necessary. Please see their travel advice if your normal journey includes one of these operators.

There will be fewer Thameslink services on the following routes:
