Thousands of rail and Tube passengers will be hit by strikes this week in separate disputes over the role of guards and working conditions.
Members of the RMT union at Southern and Greater Anglia will walk out for 24 hours on Tuesday and Thursday in rows over staffing and driver only trains.
The Southern dispute is now in its 18th month, with no sign of the deadlock being broken.
Meanwhile members of the drivers' union Aslef on London Underground will strike in Thursday in a row over working conditions.
Here's how journeys could be affected.
- GREATER ANGLIA
Greater Anglia says it is expecting to run a full service.
The following Greater Anglia routes use conductors:
- Norwich to London, Cambridge, Lowestoft, Great Yarmouth, Sheringham
- Ipswich to Cambridge, Lowestoft, Felixstowe, Peterborough
- Marks Tey to Sudbury
- Manningtree to Harwich
- Clacton/Walton-on-the-Naze to Colchester
Southern says services on most routes will operate normally, but there will be some alterations. For full details click here.
