Port Erin railway station is the western terminus of the narrow-gauge Isle of Man Railway and today the only surviving original outer terminus of the line. It opened on 1 August 1874 with a modest station built of local slate rubble, but growing tourist traffic to the resort led to a substantial rebuild in Ruabon brick between 1902 and 1909, adding a booking office, a ladies' waiting room and a café in the former porters' office. The adjoining locomotive shed (1907) and goods shed (1908), both built of local stone, still stand beside the platform; the goods shed became the entrance and shop for the Isle of Man Railway Museum after a 1998 renovation. The museum, housed since 1975 in a former bus garage, displays historic locomotives including No. 16 Mannin (1926) and No. 6 Peveril (1875), plus carriages once used to carry Queen Elizabeth II and the Queen Mother. A regeneration programme between 2016 and 2018 re-roofed and restored the station buildings and reinstated an original roof ventilator.
