The Strathspey Railway (SR) in Badenoch and Strathspey, Highland, Scotland, operates a 10 miles (16 km) preserved railway from Aviemore to Broomhill via Boat of Garten, part of the former Inverness and Perth Junction Railway (later part of Highland Railway) which linked Aviemore with Forres. It is one of only a handful of primary/secondary main lines to be preserved in Britain today.
The Strathspey Railway operates from Network Rail's Aviemore railway station. Until 1998 the railway's southern terminus was Aviemore Speyside about 300 yards further north. Aviemore Speyside is no longer in regular use, though it has been retained as a fallback in case of problems with Network Rail. Its signal box, which was formerly at Garve West and transported from there in 1986, was retained when the station itself shut and new features are gradually being brought into service, using traditional British Railways mechanical semaphore signalling, to control a new crossing loop which has yet to be installed.
From Aviemore, the line passes the four road locomotive shed which was constructed by the Highland Railway in 1898. The original purpose of the shed was to house locomotives for the lines to Perth and Inverness (via Carrbridge and Forres). It was common for original Highland Railway engines to be allocated to the shed and in London, Midland and Scottish Railway (LMS) days it housed Stanier Black Fives, Pickersgill Bogies (Caledonian Railway), Caley 439 tanks, Caley 812 classes, and Fairburn tanks. In British Railways days the shed was allocated the shed code '60B'. These days the engines that are in traffic on the Strathspey Railway (SR) bear the 60B shedplate on their smokebox. There is also a carriage maintenance shed which was erected and opened for use in 2005; this shed allows the railway's volunteers and staff to work on its fleet of coaches indoors. On the opposite side of the line is a three road carriage storage shed erected and opened in 2011; this allows the coaches to be stored under cover and protected from the weather. Coaling is carried out at Aviemore using a facility constructed in 2014 on the site of the former Aviemore Speyside station building.
