Dozens of ScotRail services continue to be cancelled due to an ongoing staffing dispute.
The rail operator has warned passengers to check their schedules before travelling, as a shortage of train crew has affected over 80 services.
On Sunday, July 7, approximately a quarter of services were cancelled, resulting in some routes operating less frequently or ending earlier than usual.
The disruption stems from fewer train drivers working overtime amid a pay dispute with the union Aslef.
Key routes impacted on Monday include services between Edinburgh and Helensburgh, Glasgow Central and Largs, and Aberdeen and Edinburgh.
Aslef notified ScotRail on Friday, July 5, that it was considering a ballot for industrial action over the pay dispute.
Several train drivers have refused to work extra Sunday shifts and overtime, significantly impacting services.
Traditionally, the rail industry relies on drivers taking on extra shifts as overtime, particularly for Sunday services.
ScotRail, now government-owned, expressed concern that shifts needing short-notice coverage during the week, such as those arising from illness, would also be difficult to fill.
Aslef has criticised the Scottish government for failing to address driver shortages and pay issues.

The union’s Scotland organiser, Kevin Lindsay, says the government should have predicted these problems.
He added: “The Scottish government is the sole shareholder of ScotRail yet have completely failed to address the driver shortage.
“This is a crisis entirely of their own making.”
Adhering to the Scottish government’s public sector pay guidelines, ScotRail made a pay offer on Friday.
Mark Ilderton, ScotRail’s service delivery director, apologised for the inconvenience caused to customers.
He said: “We want to resolve the pay dispute matter with trade unions and will remain fully committed to further discussions.”
ScotRail plans to recruit 160 new drivers annually over the next few years to address the shortage.
This recruitment drive aims to tackle the backlog of driver training during Covid-19 when pairing an instructor with a trainee was not feasible.
