Originally part of the North Wales Narrow Gauge Railways, Tryfan Junction Station lay at the junction between the original line from Dinas Junction (nprn 91421) to Bryngwyn (opened 1877) and the later line to South Snowdon (opened 1878). It later became part of the Welsh Highland Railway (nprn 91420); the stone station building has recently been restored.
