Trains do have the advantage that they don't have to deal with road congestion. Since buses have to use the same streets as cars unless there are bus only lanes it's pretty much always going to be faster to drive than to take a bus because the bus probably won't be doing directly to your destination and will be making stops where you won't in your car.
