Communications and train location systems. For management larger locomotives meant longer trains that make more efficient use of the tracks. UNIT trains moving just one product made more efficiency for the the cars used for this service.

railroads themselves have been around for centuries. There is a church in Germany with a window shat shows children pulling a rail car in a mine. It was common to use children to pull rail cars in mines because they were small and their bodies would fit in the tunnels. Outside of the mines draft animals were used to pull empty cars. Generally, a gravity railroad was used to move coal or ore from the mine to a waterway and draft animals would pull the car back up hill. Maintaining draft animals was expensive. They had to be fed and cared for whether they worked or not. And in the late 18th century the price of their fodder increased greatly. Mine owners began looking for cheaper ways to move coal and ore. In 1804 Richard Threvick built the first steam locomotive. It could pull 10 coal cars. Slowly steam locomotives improved and the first really practical one was The Rocket built by George Stephenson about 10 years later. The innovation of the steam locomotive to replace draft animals and humans added a hugh amount to the efficiency of the railroad.
