The RMT union has said that it will be taking further industrial action over three dates in early November.
November 3, 5 and 7 have been confirmed as strike days, which will likely lead to rail disruption for a week-long period.
In a separate strike, RMT workers on the TfL London Underground and London Overground networks will walk out on November 3.
The latest strikes come as tensions continue to boil over between unions and Network Rail, train operators and the Department for Transport over wages and working conditions.
RMT is accusing Network Rail of having “reneged” on an earlier pay offer and seeking to “impose job cuts, more unsocial hours and detrimental changes to rosters.”
The offer in question was reportedly an increase in salary of four per cent this year followed by four per cent next year, plus additional benefits such as discounted travel for staff and their families.
However, Network Rail has denied this, saying that its offer revolved around extending the guarantee of no compulsory redundancies prior to January 2025.
Mick Lynch, the RMT general secretary, accused Network Rail of “dishonesty” in the talks.
Network Rail’s chief negotiator Tim Shoveller hit back by suggesting that the union was intent on holding “more damaging strikes rather than giving their members a vote on our offer.”
Shoveller added that the rail sector had been left with “many fewer passengers” using the rail network since the pandemic which had left a shortfall of £2 billion in its budget.
Network Rail also said that it had a two-year eight per cent pay rise deal for staff “on the table ready”.
