Railway Regulation Act 1844, compelled "the provision of at least one train a day each way at a speed of not less than 12 miles an hour including stops, which were to be made at all stations, and of carriages protected from the weather and provided with seats; for all which luxuries not more than a penny a mile might be charged". It enabled poorer people to travel for work. [i] These trains became known as 'Parliamentary Trains'
