Work to revamp a section of railway in Aberdeen is under way.
Network Rail is renewing tracks on the Hanover–Waterloo line until December 8.
The route might not be well-known to travellers as the line does not carry any passengers.
It is a stretch of freight railway that links Waterloo Quay into the rail network before branching off from the passenger railway at Kittybrewster.
The line runs through a number of Granite City neighbourhoods including the Beach Boulevard, King Street, Mounthooly and Kittybrewster.
The work is scheduled to take place 24 hours a day, according to letters sent to city properties last month.

Evelyn Brown, community relations manager for Network Rail in Scotland, has already apologised to residents for the work.
She said: “Although this work is essential, I would like to apologise in advance for any disturbance it may cause you.
“This work will involve renewing 2,384 yards of track and railway components on the Hanover–Waterloo line.
“Unfortunately, the equipment we use – in this case engineering trains on the track – means that some noise is unavoidable.
“We will do all we can to minimise it and we have also asked those working on site to work with consideration for the local community.”
