Formed from the merger of the Inverness & Aberdeen Junction and the Inverness & Perth Junction railways in 1865, the Highland ran from Perth in Central Scotland north to Inverness and then on up to Wick and Thurso.
From Dingwall it ran west to Kyle of Lochalsh to serve Skye and the Western Isles.
Another line ran east from Inverness to Keith, where it connected with the line to Aberdeen.
Several branches were built to serve nearby towns. In addition to inheriting several locomotives from its constituent companies, the Highland Railway was renowned for its distinctive stable of locomotives.
Many of these were built at the company's works at Lochgorm, Inverness.
Locomotive superintendents for the HR were William Barclay, William Stroudley, David Jones, Peter Drummond, F.
G. Smith and Christopher Cumming. Jones and Cumming in particular produced some outstanding designs such as the F 'Bruce', Strath, Jones Goods, the Small and Large Ben (mountain), the K 'Barney' classes, not to mention the Snaigows and the Clans.
They included not only the large named trains for passenger services, but also the humble shunters. A fascinating new archive of the Highland Railway's locomotives featuring over 150 photographs and images.
