Trainz Railroad Simulator 2004 gives users the opportunity to be the engineer during high-speed passenger runs, 200-ton logging hauls, or car-switching in a busy industrial yard. The developer -- Auran -- has also doubled the amount of free downloadable content, which will be periodically updated and available to owners of Trainz 2004. Players are also able to design their own routes, create landscapes, and set production quotas in the "Operations Manager" mode. Drivers can be given assignments, schedules can be set, and commodities manipulated in the supply/demand marketplace. ~ All Game Guide
