Barmouth viaduct Swing Bridge.

A view from the Barmouth side of this impressive viaduct showing far more detail of the old swing-bridge. Unfortunately it no longer swings but it functions quite well as a rail bridge. We see here too some pedestrians talking a stroll over the viaduct for which there is normally a small toll.
The train is in fact a tfw (Transport for Wales) Class 158 DMU doing the Cambrian Coastal route from Pwllheli to Mchynelleth, possibly the 2J23 service.

See next photo for another view of this bridge.
