and steep track grades. In general, the player should balance the cost of operating a train and the time required to transport cargo, with the balance being that the profit from cargo delivery outweighs train operating costs. The player also may purchase various industrial plants to earn extra money based on the amount of cargo received and delivered. Basic industry, such as bakeries, textile mills, and tool and die factories, earns less profit than advanced factories such as canneries, steel mills and automobile plants, although the latter require multiple goods delivered to produce one final product. Furthermore, idle industries which do not produce goods will generate a negative profit, thus increasing overall operating costs and overhead. Which locomotives are available depends on the time period and scenario. All locomotives begin their operational lives with a set chance of mechanical failure, with some types more prone to breakdowns than others. Breakdown percentage chance increases the older a locomotive becomes. A train may also suffer a wreck, which completely destroys the locomotive and all hauled cargo. Economics Gameplay also includes financial manipulation of companies, issuing bonds, share repurchases, stock issues, manipulating dividends, merging with other companies and declaring bankruptcy. These features are required in some scenarios and may be used for either great financial gain or total fiscal disaster. In normal financial mode, the player may buy or sell any companies' stocks at various prices depending upon the economy. On advanced settings, the broker may allow the player to buy on margin or short sell stocks if he has enough value of stocks or cash to rely on. The computer players may also engage in these practices and will attempt to bankrupt the player when he is heavily in debt. The economy may fluctuate during gameplay, with five economic states possible: Booming, Prosperity, Normal, Recession and Depression. When the economy is good, the revenue of hauled goods and stock prices will be higher. Bond interest rates will also be adjusted with the economy level, including the interest received from cash and the interest paid for the bonds.

The missions can be played on three difficulty levels, and each also includes three listed objectives.
