Railroad Tycoon II is a railroad simulation that covers the history of railroads from the late 1700s to the 2000s. The player assumes the role of the chairman in a railroad company, trying to make profits for the investors (often but not necessarily including the player themself) and completing various other objectives while being hindered by rival companies, train breakdowns and train robbers.
Most of the gameplay consists of building tracks, stations and trains, which are used for hauling goods from one station to another. Money received from hauling is determined by the distance between the two stations, the demand and value of the delivered goods, station improvements and the difficulty level.
