RAIL engineers will work around-the-clock for 10 days to complete upgrades in Forres and Elgin.
A replacement bus services will operate between Inverness and Keith from Saturday, October 7, until start of service on Tuesday, October 17, to help minimise disruption for passengers.
Delivery director for Network Rail, Matthew Spence said this is a vital phase of the Aberdeen-Inverness improvement project.
He added: "Our engineers will complete this complex programme as quickly as possible. We understand the inconvenience these works will cause to some passengers, residents and motorists and we are working hard to keep disruption to a minimum."
During the closure of the line, Network Rail and contractor BAM Nuttall will: complete 1.5km of new track in Forres; finish the new Forres station and link road; complete 1.2km of new track in Elgin; extend the platforms at Elgin; upgrade Elgin level crossing to a full-barrier, CCTV crossing; remove redundant signal boxes at Elgin and Forres; and upgrade signalling systems between Elgin and Inverness.
The Aberdeen-Inverness Improvement Project will provide a day-time hourly commuter service between Inverness and Elgin by December 2018 and a half hourly service between Aberdeen and Inverurie by the end of 2019, and increase end-to-end services to an hourly frequency in the longer term.
