Journey times on the Glasgow to Aberdeen route have increased since 2007 due to increased interaction with other operators, both passenger and freight. However, several ScotRail services now make additional calls on the route, providing enhanced connectivity for passengers.

The improvement in journey times between Edinburgh and Aberdeen is attributable to the Edinburgh Fife Aberdeen project, sponsored by Scottish Ministers and delivered in 2008.
A slight increase in average journey times between Aberdeen and Inverness is attributed to the provision of an extra service since 2008. However, the timetable has been continually developed to provide a reliable and robust service for passengers. A program of enhancements for this route is currently in development for delivery between 2014 and 2019.
An improvement in journey times between the Central belt and Inverness has been delivered through Phase 1 of the Highland Mainline improvement project.
