The line left the IoMR on the outskirts of Peel near Glenfaba Mills and climbed steeply in a southerly direction for about 0.7 miles (1.1 km) until it reached the village of Patrick.
The line then turned west along the access road into the internment camp which had been built in the grounds of Knockaloe Farm.
The branch, and Knockaloe station at its terminus, opened on 1 September 1915 and closed on 14 October 1920.
[1] The station and line were used to transport internees, other persons, food and supplies to and from the camp.
In addition to the loco shed, traces include the remains of concrete bridge abutments on the old course of the River Neb at the end of an embankment which crosses a section of ground called the Raggat.
