Further rail strikes on Sunday
More rail strikes will be held this weekend.
Strike negotiations may be required in order to resolve ongoing disputes about pay between Aslef members and Arriva Trains Wales.
The rail has offered a package which it says is in excess of 12 per cent over two years and would bring drivers' salaries to £39,117 for a 35-hour, four-day average week.
However, union officials claim their members are unhappy with the conditions attached to the offer, which would see drivers made to work Sundays on a rostered basis, rather than it remaining voluntary.
Stan Moran, Aslef district organiser for Wales, said: "Yes they are offering 12 per cent but what they don’t say is what they want for that 12 per cent. It's not just about the money, it's about conditions."
On Monday (February 28th), Aslef members also held a 24-hour strike after talks with Arriva Trains Wales bosses proved unsuccessful and they are now set to take further action on Sunday.
Aslef is Britain's trade union for train drivers and has more than 18,500 members.
