There aren’t many people who’ve personally made a Metro happen.

Big infrastructure products normally start with a regional or national Government drawing lines on a map.

The South Wales Metro started with Mark Barry coming back from Milan and saying “we should have one of those” - and then refusing to shut up about it.

Today’s episode is a fascinating account of how to make transport change happen in the real world, with powerful lessons for anyone whose role is transport change - or who just wants transport change.

This is one of those episodes I particularly hope you’ll listen to.
