Narrow gauge industrial railway, 12 @ 3 foot

The Twrch is a tributary of the Tawe [Swansea] River and lies on the boarder between the Brecon Beacons and the 'Valleys' [industrial South Wales]. The valley is a natural route between Swansea & Beacon and has an interesting industrial history [see Industrial archaeology of Cwm Twrch by Dilys Powell].
The second of four layout related to the valley Henllys represents a rural halt with loading dock and quarry loader. The halt is not a block post so is unsignalled with points operated by point leavers unlocked by a key on the train staff with the loop serving the loading dock is a double ended siding

The photos follow a push pull towards Brecon and then show the halts goods facilities
