Dinas is a station on the narrow gauge Welsh Highland Railway, which was built in 1877 as the North Wales Narrow Gauge Railways Moel Tryfan Undertaking to carry dressed slate for trans-shipment to the LNWR. Passenger services ceased on 26 September 1936 until which time Dinas had been a joint station, known as Dinas Junction with the LNWR and later the LMS. In 1951, British Railways closed their part of the station but the line through the station remained open until the line from Caernarvon to Afon Wen was closed in 1964. The trackbed was subsequently developed as the Lôn Eifion tourist cycle route.

The Ffestiniog Railway is a heritage railway based on 1 ft 11+1⁄2 in narrow-gauge, located in Gwynedd, Wales. It is a major tourist attraction located mainly within the Snowdonia National Park.
