Route

The Biggest Little Railway In The World (abbreviated to BLR) ran 71 miles from Corpach Locks to Inverness Castle. The line was constructed along the length of The Great Glen Way, alongside the Caledonian Canal and for some of the route, followed the track bed of the former Invergarry and Fort Augustus Railway.

The railway was built to transport a miniature steam locomotive from Fort William to Inverness, creating the longest 32mm gauge railway in the world. Construction of the railway began at Corpach on 20th June 2017 and was completed at Inverness Castle on 1st July 2017. During the 12 days of construction, track was laid by four track laying teams, made up of volunteers from a variety of backgrounds.

Due to the nature of the terrain encountered by the railway, a number of special engineering solutions were devised in order to carry the train over obstacles. These included:
 * Derrick and Train Ferry at Banavie (Neptune's Staircase)
 * Truss Bridge at Laggan Locks
 * Viaduct at Aberchalder Spillway
 * Trestle Bridge at Inchnacardoch
 * Counterbalance Railway at Inchnacardoch
 * Rack and Pinion Railway north of Drumnadrochit
 * Helix Spiral at Inverness
