ScotRail's temporary timetable is to be extended to include Sundays amid ongoing train disruption.
It has been confirmed that the temporary timetable in place will include Sundays from June 5.
Train bosses are currently battling the staff shortages that came in the wake of the Covid-19 pandemic. The shortages have caused ScotRail to clash with trade unions, who say the drivers are being overworked.
ScotRail said they are doing everything they can to minimise disruption and and inconvenience and will look to 'resolve this dispute with the trade unions and move forward together'.
A statement from ScotRail said: "ScotRail is introducing a temporary timetable for Sundays to provide greater certainty and reliability for customers. This follows the introduction of temporary timetables for Monday – Friday and Saturday.
"The train operator has brought in the temporary change as a result of a significant number of drivers declining to make themselves available for overtime or rest day working following a dispute about pay.
"Like many train operators across Britain, ScotRail has relied on drivers working overtime or on their rest days. In 2019, ScotRail committed to employing more drivers to phase out the reliance on this practice, however, the pandemic meant that driver training was significantly delayed.
"The changes to the timetables follow an announcement by the drivers’ union ASLEF that its Executive Committee has rejected ScotRail’s improved pay offer made last week. It did not even recommend allowing its members a say on the offer via a referendum.
"Customers will be able to see the new temporary timetable for Sunday on our website and app from Saturday morning, as customer information systems are currently updating."
ScotRail has been coming under increasing pressure to resolve a pay dispute with the Aslef union which has seen drivers across the network refuse overtime and rest day working.
As a result, about 700 services have been cancelled and ScotRail has implemented a temporary timetable.
David Simpson, delivery director for ScotRail, said on Monday: “We’re sorry to customers for the disruption on Sundays over recent weeks so this temporary timetable will provide greater certainty and reliability for customers.
“We’re incredibly disappointed and frustrated that ASLEF bosses have rejected this improved pay offer. It’s astonishing that they will not even put this offer to their members.
“Our substantially improved pay offer reflects the cost-of-living challenges faced by families across the country, while balancing it against the need to provide value for the taxpayer.
“We have offered to meet ASLEF but, in the meantime, would urge them to reconsider this offer in the interest of their members and the future of the railway in Scotland.
“We’re asking customers to check their journey on our website, mobile app, and through our social media channels as train times will have changed.”
