Tfl has warned commuters of cancellations as the 'Beast from the East' is predicted to bring freezing temperatures and snow to the south east.

Network Rail will be operating a reduced timetable on key routes tonight and tomorrow so that more de-icing trains can operate. 

Jon Fox, Director of Rail, said: “I’d like to thank our customers for their patience while we action Network Rail’s requirement for an emergency timetable on TfL Rail and London Overground.

"We are working closely with Network Rail to do everything possible to minimise the consequences of the forecast severe weather on Londoners and ask customers to check before they travel, using our website or our Twitter feeds.”

Services will be reduced tonight, with Overground services being stopped at 10.15pm. 

On Tuesday, services will start later than normal, at about 6am, with some lines running on a reduced timetable. 

West Anglia services will operate a Saturday service but with no service to Cheshunt.

The Gospel Oak to Barking line will operate three trains per hour.

The North London line will operate four trains per hour between Clapham Junction and Stratford.  No service will operate to Richmond.

Services from Romford to Upminster will not operate.

On TfL Rail, services on Monday evening will finish at 11pm. A reduced timetable will then operate on Tuesday:

The first service from London Liverpool Street will depart at 7.10am.

The first service from Ilford to London Liverpool Street will depart at 7.17am.

The first service from Shenfield will depart at 7.21am.

The last service from London Liverpool Street will depart at 9.40pm.

The last service from Shenfield will depart at 9.11pm.

In between these times, a ten minute service will operate with trains calling at all stations.

Commuters are being warned to check and plan their journey ahead of time incase of cancellations or delays.
