Well for my commute the trains are every 30 mins or so - pretty convenient times and a short walk from the office. The ticket is cheap, much cheaper than a days parking and during the trip I get to sit, look at the view and sip a coffee. The train is way more relaxing than the equivalent drive - which due to traffic levels at rush hour would probably take twice as long (at least) and be extremely unpredictable.

So when I have the option I'd rather take the train - of course I also drive a lot of places.
