Commuters face a second day of strikes today as staff on Greater Anglia trains are taking industrial action over driver-only trains.
The company says it's trained extra staff to take their place and are planning to run normal timetables during the action.
There was only limited disruption during the first strike on Tuesday.
Union members working for Greater Anglia and Southern Rail walked out at midnight in the ongoing dispute over safety and the role of guards on trains.
Sixty per cent of trains, mainly commuter services to London from Essex, Cambridgeshire, Hertfordshire and Ipswich, don't have conductors.
