It was connected to the London and North Western Railway line at Foryd station by the short, steep branchline that formed the Kinmel Camp Railway.
Between 1916 and 1917 a branch was laid to avoid the steepest gradients at the camp terminus.
By 1918 a connection had been added to the Vale of Clwyd Railway's line from Rhyl to Denbigh.
After the end of the First World War, the line continued in use serving a quarry near the site of the camp at St. George.
The railway continued in this capacity until it closed in 1964[2] or February 1965, with the track being lifted two months later.
