Frame from video of likely the last ever steam engine to cross the now demolished (and replaced) Pont Briwet combined road/railway trestle bridge. The full video clip is located on You Tube (see link to original item). 720x1280 resolution. The locomotive is Stanier Black Five Class 5MT 4-6-0. The clip shows the return (south-bound) part of the then daily summer steam excursions from Machynlleth to Pwllheli. As cameraman I was aware that the summer season of these trips was about to end, but what I did not realise at the time was that with the subsequent introduction of a new electronic train signalling system, this would make steam trains incompatible so no further steam excursions were run along this line. Then, in 2013/14 the Pont Briwet timber trestle bridge itself was demolished and replaced by a new concrete structure with separate road bridge. This image and the video clip therefore captures the very end of two important facets of the industrial revolution in the area, the use of steam locomotives to haul trains on the Cambrian Coast railway and the distinctive trestle bridge and road toll across the Afon Dwyryd.
