I love this because it shows how you can build a system that gets everybody within 30 miles or so of a station.

The tricky part is not getting the majority of people  within 30 miles of a potential station location at every wheat silo on a railway line - especially in the Midwest, where the towns and cities were originally built by and for rail ... its sorting out the finance in our upside down public finance system to run the passenger services to offer transport services at those stations.

I've been accused of being a Marxist, yet while Harpo's my favourite, it's Groucho I'm always quoting. Odd, that.
