In 1948 the line became part of the Scottish Region of British Railways following nationalisation and remains open as a route to Fort William, Mallaig and Oban.

In 1906, when King Edward VII came by train to the area before continuing to Fort William and he was welcomed at Whistlefield by the stationmaster George Gall, with flags and other decorations adorning the whole station.

[10] The single platformed station, without a passing loop, was located on a steep section of the line between the Garelochhead and Finnart Viaducts.

The Whistlefield Store and tea room, later the 'Green Kettle Inn' was built close by[13] to capture the trade created by the railway with steamer excursions on the loch, picnickers, etc.

[20] A water balance funicular railway had been proposed from Whistlefield down to Portincaple to carry passengers using a steamer service at a new pier.
