I wasn't aware of this upgrade. Does this upgrade include upgrading the single section of track at Unay to double track?

North-east rail upgrades on track for 2026 completion
Railway upgrades that could slash journey times between Aberdeen and the central belt by more than 20 minutes are on track to be completed in five years'

Major improvements are to be carried out to the East Coast Main Line as part of the Aberdeen City Region Deal at a cost of £200 million.
There have been repeated calls for the line to be upgraded for more than a decade, with business chiefs claiming shorter journey times will lead to more business opportunities and encourage new visitors.
Initial plans to upgrade the stretch through the Usan junction were ditched after it emerged it would save just two minutes.
But proposals for wider upgrades along the route are expected to deliver far more radical results.
Quicker journeys between key cities
A series of proposals including line speed enhancements, signalling improvements and more passing loops could cut 24 minutes from journeys between Aberdeen and Edinburgh, to two hours and 10 minutes.
Eight minutes would be saved on journeys to Glasgow, down to two hours and 30 minutes.
And trips to Dundee would be three minutes quicker, at one hour and 10 minutes.
Transport Scotland had earmarked 2026 for completion of the work, and a new report has revealed the project is progressing on schedule.
An options selection process relating to stations along the route is also expected to be completed in July, and is described as “progressing well”.
