Rail workers at Arriva Cross Country are to stage a month of industrial action in a row over pay and working conditions.
It will include a ban on overtime and refusing to pick up litter from trains.
The Rail Maritime and Transport union said the action will start next Monday and continue until September 2 following a 4-1 vote in favour of a campaign short of a strike.
The union claimed that industrial relations had broken down at the company, which runs services across England and into Wales and Scotland.
General secretary Bob Crow said: "Our members have shown their anger at the divisive approach taken by Arriva Cross Country in respect of pay and a wide range of issues relating to working conditions, and this action is aimed at forcing the company back to the table to negotiate a fair deal for all staff.
"This is just another example of a rail franchise company looking to maximise its own profits at the expense of the workforce and RMT members have demonstrated in the ballot just how determined they are to secure justice."
