The long-running, bitter dispute between the train drivers' union, Aslef, and 14 English rail operators over pay and working conditions has erupted into yet another round of industrial action.
Train drivers want a rise without conditions as well as local negotiations to upgrade working practices, which will means additional costs for the employers. According to Aslef, some drivers haven't had a pay increase in five years.
The general secretary, Mick Whelan, said: "We are going on strike again, not to inconvenience passengers, but to express our disgust at the intransigence of this government and the bad faith shown by the private companies which employ us."
Which train services are striking on Thursday?
CrossCountry and GWR are the train companies striking today (Thursday, December 7).
Cross Country has warned there is likely to be last-minute changes to services until Saturday, December 9, and they will have a nine-day overtime ban in place.GWR also said there is likely to be “further disruption” until Saturday, December 9, because of “industrial action short of a strike which is likely to cause some short notice alterations and cancellations".
What journeys and areas will be affected?
CrossCountry: No services at all.
GWR: There is a reduced and revised timetable to all services by GWR. Many parts will have no service and any trains that are running will only be operating for a “limited period” during the day between 7am and 7pm. The revised timetable can be seen here.
