I went up to Ebbw Vale by train about 18 months ago, specifically to go across to check out the Sirhowey area. At that time the train ended at Ebbw Vale Parkway - somewhat short of the town. I see today it has been extended to the town itself?
As it happened, having taken a cab from the Parkway to the town, I bumped into someone I had known 40 + years previously in Uni. We ended up having a few beers in the town itself, then a cab back to The Parkway for me and a memorable ride back to Cardiff.
So, Sirhowey is still a spot on the map for me rather than somewhere I have visited!
