Why Do Progressives Love Trains?

Because they live by a world view that peaked in the late 1800s, trains are a nastalgia thing for them... Plus trains like planes do offer mobility, but it is limited, just like buses... sure you can go, but on their schedule and only where they go.
Automobiles give true mobility, you are not dependent on anyone or anything else to get where you want to go... A privately owned network of gas stations are all you need, and you can go wherever and whenever you want. There is nothing that gives an individual freedom and convience that an automobile does when it comes to mobility.
