Milk churns being unloaded from a train at Paddington station. The milk had come from stations between London and Plymouth. In the early 20th century the amount of milk being brought into London by rail was rising rapidly. The city was growing and farmers were pushed further away from the centre of London. The coming of the railways meant that milk could be transported long distances quickly and therefore it could stay fresh for a longer time.
