UK rail operators and the union leading the biggest strike in three decades are set to hold talks to try and resolve the impasse, with further disruption expected throughout the country.

While some 40,000 rail workers are due back at work after Tuesday’s initial walkout, further strikes planned for Thursday and Saturday mean only 60% of trains are expected to be running, according to the BBC.

Further negotiations between the two parties are set to take place Wednesday, the National Union of Rail, Maritime and Transport Workers said in a statement, though any agreement is unlikely to come soon enough for the next strike to be called off.

The two sides appeared far apart during a series of media interviews this week, clashing angrily over the demands and reasons why transport budgets have been cut. Prime Minister Boris Johnson told ministers they must be ready to “stay the course” during the dispute, which lawmakers see as part of the wider fight against the soaring cost of living.

Millions of Britons opted not to attempt to travel as a result of the strike, with many reverting to pandemic lockdown-era home working. Many stations were left practically empty and shopping streets deserted, with London Underground journeys down 95%.

“Our members will continue the campaign and have shown outstanding unity in pursuit of a settlement to this dispute,” RMT General Secretary Mick Lynch said in a statement.
