Snowdon Ranger is a station on the narrow gauge Welsh Highland Railway, which was built in 1878 as the North Wales Narrow Gauge Railways Moel Tryfan Undertaking, to carry dressed slate to Dinas Junction on the LNWR.The station was originally known as Quellyn Lake but was renamed after the path to the Summit of Snowdon popularised by, and named after, the local mountain guide, "The Snowdon Ranger", who went by that name for many years. Certainly the name "Snowdon Ranger" was in common use on company timetables from as early as 1879, and that of the adjacent Snowdon Ranger Hotel from at least 1869.
