We have regional commute rail in the SF Bay Area and in the NYC Metropolitan Region. It doesn't seem to have done much except drive up housing prices near rail stations and create silliness like 5-yr waiting lists for parking at them.

It seems clear that commuter rail is not a silver bullet. Housing density is probably what we really need.

It's both. Rail lets you be more flexible about where to put that density.

Counter-anecdotes: in Chicago (e.g., UP-N), Boston (e.g., Fitchburg), and much of Europe (e.g., many major cities in Germany), the commuter rail systems do take you out into very affordable areas.

I used to commute into SF from Redwood City with the Caltrain. If I couldn't have taken a bike with me on the train, it would have been impossible because the last mile at both ends was completely undoable with local buses.
