caption_attribution_description: English: Northern end of Pencader Tunnel This is the north entrance of Pencader Tunnel. The gates that block the entrance can clearly be seen down on the valley floor at the level of an adjacent river. The tunnel was part of the now dismantled line from Carmarthen to Aberystwyth.
context_page_description: Pencader Tunnel is an abandoned railway tunnel on the old trackbed of the Carmarthen to Aberystwyth main line in south-west Wales. It was originally bored for the Llanpumsaint-Pencader section of the Carmarthen & Cardigan Railway.
  It is approximately 985 yards long, making it the longest tunnel in West Wales and is bored through Ordovician shales. It is single-track and built to the C&C's adopted broad gauge dimensions, as opposed to the smaller standard gauge used on Britain's railways today. It is also known as alternatively Alltwalis Tunnel and Dolgran Tunnel to local villagers.
