Cotswold Line train operator Great Western Railway has announced that there will not be any trains on the route for the whole of the weekend of July 30-31.
Services were already set to be suspended all day on Saturday, July 30, due to strike action over pay by GWR train drivers who are members of the ASLEF trade union.
GWR had previously said services could be disrupted on Sunday, July 31, in the aftermath of the strike, but has now announced that there will not be any GWR trains on Sunday between Oxford, Worcester and Hereford. The company said on Twitter on Friday afternoon that there was a lack of staff.
And GWR servcies between Gloucester, Stroud and Swindon will also be suspended on Sunday.
There will be a later start to Sunday services than usual on other routes and a modified timetable will be in operation between Oxford and London Paddington.
