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.
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.
The branch line ended at Faslane Bay, where an extensive layout of sidings was provided.
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.
