Cardiff and the Valleys are ideally suited to public transport because the geography forces development into narrow corridors with rail and road links running along them. The industrial past left a dense network of railway lines that are were originally primarily for coal and ore, but lend themselves to conversion to light rail or metro. Sadly a lot of useful routes were closed, in particular east to west between the Valleys (you can look at old maps and weep at the opportunity that was thrown away) but what remains is still more extensive than in many city regions.
