If you’re planning to travel on trains to or from Paddington over the August bank holiday weekend, the best answer is probably not to.

Rail workers on First Great Western have announced a series of strikes in their long-running row over new trains.

Members of the Rail, Maritime and Transport union, including drivers and guards, will walk out for 24 hours on August 23 and for 72 hours from August 29.

Other union members who work on maintenance will strike on August 29 and 31.

The union is in dispute over the introduction of new Hitachi inter-city trains, saying the role of guards will be reduced and buffet cars' facilities removed.

RMT general secretary Mick Cash said: "Despite strenuous efforts by our negotiators we have not been able to secure the kind of progress required in the key areas of jobs, services and safety for us to reach an agreement.”

Union members staged a 48-hour strike last month which disrupted services at FGW, which runs trains to and from London Paddington, South Wales and the South West.
