If you failed to pre book a month in advance, it used to cost over £150 for a return trip to London from Bath which got you in before normal business hours, and you very often did not get a seat for that (making it impossible to spend the time productively, one of the key benefits of train travel). If you have three colleagues travelling together for a meeting, driving or even taking a car service is invariably cheaper.
