 During the Great War a spur was constructed from the main line to the alien internment camp at Knockaloe Farm, worked exclusively by the former Manx Northern Railway locomotive "Caledonia" and ceasing to exist by 1921, it ran straight into the camp itself with goods' only services; limited images of the line show the locomotive and a variety of wagons in use; the farm still exists as does the shed used to house the locomotive.This horse-drawn tramway crossed the main Douglas-Peel railway just outside the station yard at Peel and ceased to operate during the Second World War; archive images from 1937 show the line in operation with horses drawing laden wagons across the railway line in the direction of the town.The exposed coastal section of the Manx Northern Railway between Peel Road and Glen Mooar viaduct was served by a small halt in the very early days of the railway.
