The cost of travelling by mail coach was about 1d. a mile more expensive than by private stage coach, but the coach was faster and, in general, less crowded and cleaner. Crowding was a common problem with private stage coaches, which led to them overturning; the limits on numbers of passengers and luggage prevented this occurring on the mail coaches. Travel on the mail coach was nearly always at night; as the roads were less busy the coach could make better speed.
