One of the key events of my short trip to Aberystwyth was a journey along the Vale of Rheidol Railway from the town up to Devil's Bridge in the mountains. The railway is a steam heritage line which uses narrow gauge. Interestingly the railway remained in British Rail hands until 1989 and for a time in the 1970s the steam locomotives on the line were in BR blue and had the double arrow symbol!
Nowadays the engines are in GWR colours. The trip takes an hour each way and the view is breathtaking as you go higher and higher up the valley sides. I took a number of photos on the trip which you can see here.
