Northern has published new travel advice ahead of further rail strikes this month.

The Associated Society of Locomotive Engineers and Firemen (ASLEF) and the National Union of Rail, Maritime and Transport Workers (RMT) recently voted to continue strike action amidst an ongoing dispute over pay and conditions.

Members of the ASLEF union, who largely represent train drivers, will walk out on Friday 12 May, forcing Northern to cancel all services.

RMT members will then strike on Saturday 13 May, on which the train operator will only be able to operate hourly services on a small number of key routes between 7am and 7pm.

Whilst there is no strike action on Sunday 14 May, services are expected to start later in the morning than normal due to fleet displacement.

Further ASLEF action, known as ‘action short of strike’ will take place for five consecutive days from Monday 15 to Friday 20 May. 

On those dates, customers are advised to check before they travel as early-morning and late-night services may be affected.

ASLEF members are also due to walk out on Wednesday 31 May and Saturday 3 June, on which there will be no Northern services.

This month’s strike action comes ahead of Northern introducing its new summer timetable on Sunday 21 May.

Customers who make regular journeys on the same train times are advised to check before they travel as some services may have been re-timed.

This comes after the RMT announced its members ‘overwhelmingly’ backed the extension to the union’s mandate to hold further strikes.

RMT general secretary Mick Lynch said in a statement that the vote represented a de facto referendum on the dispute and strikes.

He added: “It is clear from these results that members are not prepared to accept a pay offer based on mass job cuts and major attacks on their terms and conditions.

“This sends a clear message to the employers that the huge anger amongst rail workers is very real and they need to recognise that fact, face reality and make improved proposals.

“They need to get around the table with RMT and negotiate in good faith for a better deal for rail workers,” he said. 

Tricia Williams, chief operating officer at Northern, said: “Whilst all strikes disrupt someone, these particular dates will have a significant impact on people travelling on our network to celebrate the Eurovision Song Contest in Liverpool.

“Given the context in which the UK is hosting this international event - on behalf of the people of Ukraine - this is particularly unfortunate.”
