Car is fastest, rail is second bike is third. The train is only a few minutes faster so riding the bike makes sense. Alot of times I bike one way, train the other. I find I'm too lazy to ride home some days so I leave the bike at the office and ride the train home. I probably wouldn't ever take the train, but I like to read. It works out pretty well, because I get to spend an hour exercising in the morning and 45 minutes reading on the way home (or vise versa).
