Faslane Branch

The Faslane Branch diverged west from the LNER's West Highland Railway at "Faslane Junction", beyond which was a group of exchange sidings and a locomotive shed. Northwards from here, the single line crossed a bridge, then was double track all the way to Faslane Bay. Faslane Platform stood near the junction from 1945 to 1949 serving the PoW camps that supplied labour for the Loch Sloy Hydroelectric Scheme at Inveruglas.

Near the 1 milepost was the level crossing at Shandon, where the railway crossed the road leading to Shandon station on the West Highland Railway. Sprung catch points were installed in the Up (southbound) line just south of the crossing on account of the gradient which fell steeply towards Faslane.

Near the 2 milepost, there was a quarry siding on the east side of the line, and a further set of catch points in both running lines.

A little further north was Belmore Crossing, where the railway crossed the A814 road. A signal box stood just north of the crossing, on the east side of the line.

The branch line ended at Faslane Bay, where an extensive layout of sidings was provided. The furthest extremity of the branch terminated alongside a platform.

Unusually for a British railway, right-hand running was in force over the double track, to familiarise the War Department personnel with the conditions that they would be likely to encounter while serving in Continental Europe.

In April 1946, when Faslane ceased to be a military port, the running and maintenance of the branch line was taken over by the LNER, although it continued to be owned by the War Department, and subsequently the Ministry of Defence. The branch was reduced to single track on 30 May 1946, after which all trains would use the former Down (northbound) line. Catch points were installed in the single line just south of Shandon crossing.
