Extra rail strikes have been scheduled over the festive period, the RMT union says, including Christmas Eve.
Staff at Network Rail comprising about half the workers involved in a pay dispute are expected to walk out from 6pm on 24 December until 27 December.
A new offer was made by the company on Sunday but the union is urging members to reject it.
Network Rail has accused the RMT of using passengers and workers as "pawns in a fight with the government".
The new strike dates, which are likely to affect many people travelling for Christmas, are in addition to walkouts by rail workers which have already been announced and begin next week.
Tim Shoveller, Network Rail's chief negotiator, said the RMT "are playing fast and loose with people's Christmas plans and the new strike dates announced deliberately target vital engineering work designed to improve the railway".
The RMT represents staff at Network Rail, who maintain the railways and include signallers and maintenance workers. It also represents workers at 14 train operating companies involved in strike action.
The union is involved in two sets of talks in a long-running dispute over pay, jobs and working conditions
As well as the strikes on 24-27 December, industrial action at 14 train companies across four 48-hour periods will take place on:
(i) 13-14 December
(ii) 16-17 December
(iii) 3-4 January
(iv) 6-7 January
Despite these strikes going ahead, the RMT will continue to hold talks with the Rail Delivery Group (RDG), which represents the 14 train companies, on Tuesday.
Passengers had already been warned to plan their travel well in advance over Christmas, with some 5% of the rail network shut for engineering works - although many trains do not run over Christmas Day and Boxing Day.
The RMT union is putting a new offer from Network Rail to its members in an electronic referendum, which will close in a week's time. But they are being urged to reject the offer, which its general secretary Mick Lynch said was "not acceptable".
Network Rail had said the latest offer was its "best and final". It includes:
- A 5% pay rise this year and 4% next year
- No compulsory redundancies for workers who are not managers and controllers until 31 January 2025
- A 75% discount on leisure travel for staff and their family members
Nigel Goddard in Croydon, south London, says the industrial action means that his family's Christmas has been "ruined".
He will not be able to see his son in Newcastle this December, and will miss visiting his six-month old granddaughter over the holidays.
"We have three possible days that we can meet up for Christmas lunch but there are strikes on all three of the days," he said.
The last time Nigel saw his son was September 2021. He said he will also miss out on his staff Christmas party.
"Mick Lynch needs to get into the real world and realise he is crippling the railways," he added.
On Sunday, the RMT rejected the first offer from the RDG.
The group had proposed a number of changes to working practices which it said would help to fund a pay rise for staff of 4% this year, backdated to the beginning of the financial year, followed by another 4% next year.
These include repurposing or closing ticket offices, with staff having new "multi-skilled" roles and Sunday working where it is not in place already. Other proposals by the RDG to "secure the future of the industry" included drivers operating the train doors in more areas, although it insists guards would still be on board.
There would also be a guarantee of no compulsory redundancies until April 2024.
'Compelled to take action'
Following a meeting to discuss the offer, Mr Lynch said it was "unfortunate that the union had been compelled to take this action".
"We remain available for talks in order to resolve these issues but we will not bow to pressure from the employers and the government to the detriment of our members," he added.
Transport Secretary Mark Harper said the latest developments were "incredibly disappointing".
"The RMT has failed to play its part and our rail network now faces more harmful disruption rather than helpful discussion," he suggested, pointing towards the fact that a smaller union, the Transport Salaried Staffs Association (TSSA), is putting an offer to its members from Network Rail.
The TSSA had been due to strike on 17 December but that has been called off.
The RMT, along with other rail unions who have also been striking, is seeking pay rises that keep up with the surging cost of living as well as improvements to working conditions.
The inflation rate, which measures how prices change over time, increased to 11.1% in October.
But pubs, restaurants and cafes have said they are worried that if the rail strikes go ahead in the upcoming weeks they will be severely affected, as Christmas is usually their busiest time of the year.
UK Hospitality recently warned that the strike action will cost the sector about £1.5bn in lost sales.
About 40,000 rail workers across Network Rail and train companies are expected to walk out. There is likely to be disruption in the days around the strikes as well due to trains not being in the right places.
The industry is under pressure to save money after the pandemic left a hole in its finances, and bosses say reforms are needed to modernise the railway and make pay rises affordable.
However, the rail sector is not the only industry facing strike action, and walkouts are expected to affect postal deliveries, bus services and teaching in schools this month as demands grow for better working conditions and pay increases in line with rising prices.
