Can I just make a plea for the Heart of Wales Railway. I've lived in various parts of Wales for a lot of my life and last week for the first time I travelled from south Wales to the north via the Heart of Wales line.
The countryside was absolutely stunning, helped a bit by the autumn colours. I went through places whose names are familiar but I've never visited and places I've never heard of. I didn't look at my book once. From isolated rural station buildings with a couple of houses and men planting spring bulbs in the rain to the spa town of Llandrindod Wells, it was all terrific.
Yes it took ages, but everywhere is a long journey from Pembrokeshire. The Arriva train was old and tatty but the guard was cheerful and the passengers friendly.
Give it a try before someone in an office decides it's not economic and closes it down.
