Commuters across the West Midlands are set for more misery after rail conductors with London Midland confirmed they will stage a 48-hour strike from Sunday.
The conductors are taking the action over a long-running feud about Sunday working.
The Rail Maritime and Transport union said its members would walk out on Sunday and Monday after overwhelmingly rejecting a revised offer.
"Our members have made it clear that the company's latest offer could not be accepted because it would have forced Sunday working," RMT general secretary Bob Crow said.
The workers have already staged two strikes which disrupted London Midland services and led to accusations of safety breaches, which the company has denied.
