Here's a short and interesting transport article from Planet magazine. Extract:
"Wales’ decrepit public transport system is a natural result of our decades-long love affair with the private car. Since the Beeching axe decimated Wales’ rail network, transport policy has operated on the assumption that most of us drive. The predictable result is that large swathes of the population are cut off, in rural areas especially; transport poverty soars; public health deteriorates; local ecosystems suffer; and millions of tailpipes pump carbon."
