While I certainly cheer on new SUPERTRAIN systems, it's also the case that in many places our existing systems are underused due to inappropriate development patterns around stations. There are a variety of reasons for this - sometimes they've become blight-filled neighborhoods, sometimes there are bad zoning codes and other various barriers to mixed use infill development - so implementing policy which tries to tip the balance the other way is a good thing.
An easy way to get more people to use existing transit systems is to provide desirable affordable housing within walking distance of them.
