The North Wales Narrow Gauge Railways (Moel Tryfan Undertaking) (to give it its full name) was a 1 ft 11 1⁄2 in (597 mm) narrow gauge railway running from Dinas to Bryngwyn Wales which was authorised by Act of Parliament 1872. The same act authorised a branch from Tryfan Junction to South Snowdon. Subsequently the railway chose to regard the line from Tryfan Junction to Bryngwyn as the branch.
