I don't think that your optimism is unfounded. Having lived and commuted from the South Coast for a long time, the bus wasn't something anyone other than regular commuters really thought about as an option for getting to/from Boston. On the other hand, the Commuter Rail is commonly used by people heading to games, the Aquarium, concerts, the airport, etc. The stations are very visible, train-specific, and in prominent locations as opposed to park & rides and downtown bus stations that most locals avoid. The novelty factor of riding on a train combined with avoiding traffic on the the highway is also a big part of the appeal. Cost might also be factor. Peter Pan, Dattco (when it was running) , and Bloom can cost $30 or more round trip whereas the Commuter Rail is $24.50 on weekdays and $10 on weekends with a weekend pass. Kids under 11 are free on MBTA trains but they're full-fare on the buses. Even with the stupid long ride times, it's still a better (and faster) option than the bus on most days.
