Talks are continuing today in a bid to avert a major rail strike later this week.
Trade union RMT last week called on its members working for Network Rail to strike for 24 hours from 5pm Thursday 4 June, and then for 48 hours from 5pm Tuesday 9 June.
The dispute is over pay and conditions for various groups of rail staff.
Talks took place between the two parties over the weekend, facilitated by conciliation service Acas.
A Network Rail spokesman this morning confirmed the confidential talks would continue this morning. The body has previously warned that if the strike goes ahead it will severely affect services.
Network Rail chief executive Mark Carne said on Thursday: “Our people know that there are ways to improve the way work is done.
“I have always said that if we work together to realise these benefits there is the possibility to increase pay. We are therefore ready to get around the table with whoever the RMT consider can speak on behalf of its members.
“It is clearly unacceptable for the RMT to massively disrupt the travelling public with strike action when we are ready to continue talks.”
RMT general secretary Mick Cash said on Friday: “Discussions have commenced and our full team will be in London on Saturday morning to take the negotiations forward.
“RMT is fully committed to achieving a negotiated settlement, and will be available in London for discussions for the whole weekend and beyond in order to achieve a settlement.”
