What train operators are affected?
c2c
No c2c trains will run on Monday, with its managing director Rob Mullen saying he was “really disappointed” an agreement hadn’t been reached.
“The impact of this ongoing action is significant for our customers and colleagues,” he said.
“I’m hopeful that further meetings with the unions are productive and see progress made toward concluding this challenging time for the railway.”

There will be no Gatwick Express services but Gatwick Airport will continue to be served by the limited non-stop Southern shuttle.
Great Northern
There will be no Great Northern services on Monday.
Greater Anglia
Greater Anglia said its first trains of the day will start later and last trains finish earlier than normal, excluding the Stansted Express.
An hourly train service will operate on the following Greater Anglia routes: Norwich/Colchester and London Liverpool Street, Southend Victoria and London Liverpool Street, and Stansted Airport and London Liverpool Street
A bi-hourly train service will run between Cambridge and London.
No other Greater Anglia services will operate on any other routes.
Southeastern
The operator said most of its routes and stations will be closed. There will be an extremely limited service where trains are running and the operator advised customers not to travel.
A statement said: “If you do travel, expect severe disruption, plan ahead and allow much more time for your journey.
“Trains that are running will be extremely busy, they start later and finish early.
“You may be unable to board trains at some stations, and we estimate that there could be queues for up to two hours due to the very limited service.
“Only 29 out of 165 Southeastern stations will be open. No rail replacement buses will serve stations that are closed.”

Southern said there will be no trains running across the vast majority of its network, with a limited shuttle service running non-stop between London Victoria and Gatwick Airport.

South Western Railway said a significantly reduced service will operate on a small number of lines, while the rest of its network will be closed.
Trains will only run between 7am and 7pm.
