Early railways were a far cry from the great system of railroads that were built in the nineteenth century and that continue to be used today. The earliest railways in the United States were short, wooden railways built by quarries and mines along which horses pulled loads to nearby water ways.he first German railroad, running from Nuremberg to Furth, began operation in 1835. Soon Germany had a well-developed system, and by the beginning of the 20th cent. a majority of its railroads were owned by the state. The entire system was under state control by 1922.
