Despite the sunshine, a bitter wind from the east scythes across the exposed wooden deck of the bridge and whistles around the massive arch of ironwork that once swung open to allow ships to pass. Pont Abermaw – Barmouth Bridge – carries the Cambrian Coast railway over the Afon Mawddach, on its journey south between Machynlleth and Pwllheli, as well as hosting a path for walkers and cyclists.
As I watch, the train eases around the curve on to the bridge and trundles past me. The railway has a modest single track and carries equally humble two-carriage trains, yet these form a vital strategic service for many on this coast. Children ride the train to school and older folk take it to the next town for their weekly shop, while others revel in the impressive views of land and sea.
