Train users in South Yorkshire are set to face disruption again today - when railway workers stage their third strike.
Members of the Rail, Maritime and Transport (RMT) union Northern, South Western Railway Merseyrail and Greater Anglia will walk out for 24 hours today following action on Monday and Wednesday.
Picket lines will again be mounted outside railway stations affected by the strike, and passengers face delays, cancellations and replacement buses in some parts of the country.
The industrial action forms part of a long running row over the role of guards on trains.
Northern said it would run around 1,350 services on strike days, more than half its normal timetable, mostly between 7am and 7pm.
Paul Plummer, chief executive of the Rail Delivery Group, said: "No one wins when strike action disrupts the lives of people trying to get to work, get their children to school or to run their local business.
"Working together we will minimise the impact of the RMT strikes and find a way through this dispute so that we can play our part to support Britain's economy."
