What are the pros and cons of taking public transportation?

Of course, that depends on what type of transportation you’re talking about! Here’s what I understand so far: you’re considering taking a local train as a way to get to work.  There are certainly positive aspects to this: you’d be saving money on gas, and you’d have access to the train schedule, and could know exactly when you’d arrive.  On the other hand, you’d still have to wait for the train to arrive and could still get late, and you’d have to actually spend time doing whatever you were doing.  Since you’re trying to calculate pros and cons, it might be good to include an estimate of the actual time you’d be on the train each day, as that might influence your calculation.
