The MoU sets out how the dispute can be developed and and sets out a mutually agreed way forward.
Some of the agreements include backdated payrise for 2022 as well as staff and job security guarantees.
This will now be put forward to each of the Train Operating Companies in a referendum vote.
If accepted, the MOU will terminate the national dispute mandate and will create a pause in industrial action over the Christmas period and into Spring.
A Department for Transport spokesperson said: “We welcome the RMT putting this fair and reasonable offer to its members in a referendum, marking a positive step towards resolving this dispute.
“The Rail Delivery Group's offer guarantees no compulsory redundancies and a fair pay rise, while ensuring we can take forward much-needed reform to secure the future of our railways. We hope RMT members will recognise the benefits, accept this offer and put an end to the RMT's industrial action.”
A spokesperson for Rail Delivery Group, said: “Following further negotiations between RDG and RMT, a Memorandum of Understanding (MOU) on the current dispute has been developed which sets out a process for a mutually agreed way forward, including a backdated 2022 pay rise for staff and job security guarantees. This will now be put to RMT members in each of the Train Operating Companies in a referendum vote. If accepted, this MOU will terminate the national dispute mandate, creating a pause and respite from industrial action over the Christmas period and into Spring next year, while allowing for these important negotiations on proposed reforms to take place at local train operating company level, through the established collective bargaining structures. These discussions would be aimed at addressing the companies' proposals on the changing needs and expectations of passengers as well as unlocking further increases for staff, in order to help to secure a sustainable, long-term future for the railway and all those who work on it.”
RMT general secretary Mick Lynch said: “This is a welcome development and our members will now decide in an e-referendum whether they want to accept this new offer from the RDG.”
