Network Rail have announced that buses will replace every single train between Aberdeen and Dundee on Sunday.
In what will be another frustrating blow to local rail users, engineers will be working on the tracks continuously from Saturday night through to Monday morning.
The replacement service is, however, part of a wider £13.5 million improvement project, boosting the line between Aberdeen and Stonehaven.
It aims to both increase capacity and enable trains to move through the area more safely and more efficiently.
The latest phase will result in new LED signals and axle-counters being added to the line, while the Newtonhill signal box will be decommissioned and the control relocated to Aberdeen.
It will also support improvements to rail freight operations and the overall operational capacity within Aberdeen station.
Jeremy Spence, Network Rail programme manager, said: “These works will deliver the extra capacity needed to support further changes to local services between Aberdeen and Stonehaven as well as improvements to rail freight operations in the area – which benefits both passengers and business.
“Aberdeen’s rail network is seeing huge levels of investment that will help to create more opportunities for commuting and leisure travel and help grow the economy and put passengers and freight users first.”
This latest rail interference in the north-east comes shortly after ScotRail managing director Alex Hynes said he was “very sorry” for a service that has “not been good enough”.
“We have been cancelling too many services and that’s because of a training backlog,” Mr Hynes recently told North East of Scotland Transport Partnership committee members.
“We are very sorry for the service we have provided for our customers because it is not good enough and we are working flat out to improve.
“There has been additional compensation offered to our season ticket holders, and that is on top of the standard compensation we offer to passengers when services are cancelled.
National rail have advised passengers to plan ahead and check their journey via nationalrail.co.uk or with their train operator.
