A historic steam railway in the Scottish Highlands has received an extraordinary boost thanks to a £1 million donation from a mysterious American benefactor. Strathspey Railway, based in Aviemore, said the US-based supporter, who wishes to remain anonymous, was inspired by a visit to the line several years ago.

The volunteer-run railway described the gift as "exceptionally generous," and said it would help cover operating costs and locomotive refurbishment. A spokesperson for the organisation explained: "Beyond expecting the railway to use the donation in a way which best benefits the organisation as a whole, the benefactor has not stipulated how this money should be spent nor placed any restrictions on the type of strategic projects which might be favoured."

The railway operates a 10-mile (16km) route between Aviemore and Broomhill, passing through Boat of Garten, and has been featured in TV programmes including BBC’s Monarch of the Glen, ITV’s Doctor Findlay, and three series of The Traitors, filmed nearby at Ardross Castle. The board said they are taking financial advice to ensure the donation is invested effectively for both short- and long-term projects.

Strathspey Railway preserves a part of the former Inverness and Perth Junction Railway, which later became part of the Highland line linking Aviemore with Forres. The railway maintains a fleet of steam and diesel locomotives, operated by a combination of volunteers and a small number of paid staff. The line has previously completed major restoration projects, including returning the 75-year-old Ivatt Class 2 2-6-0 No. 46464, originally built in Crewe in 1950, to working order after decades of service across Angus and Fife.
