Castletown Railway Station is an intermediate station on the Isle of Man Railway on the Isle of Man forming part of sole remaining section of the once extensive network that operated across the island. The station is the busiest of the railway's intermediate stations, being the closest to a number of local visitor attractions. In peak season service trains often pass here, making the station one of the railway's more active stopping places. The station occupies a site within walking distance of the main town and is in close proximity to the local playing fields.

The Isle of Man Railway (IMR) is a narrow gauge steam-operated railway connecting Douglas with Castletown and Port Erin on the Isle of Man. The line is 3 ft narrow gauge and 15+1⁄2 miles long. It is the remainder of what was a much larger network that also served the small western hamlet of Peel, the northern town of Ramsey and the small mining village of Foxdale. Now in government ownership, it uses original rolling stock and locomotives and there are few concessions to modernity.
