Railroads played an absolutely crucial role in the Industrial Revolution, since they made for the incredibly fast transfer of goods such as iron and steel that were used to build things--not to mention the transport of the workers themselves.
They went on safety systems, being resourceful on food and water +live stock.
They lowered payment for workers.
They increased taxes.
