Railroad Tycoon 3 has a single player campaign of sixteen scenarios, divided into four rooms. You can complete these campaign scenarios in any order, although the narrator strongly recommends doing the rooms in order.
- American Room
- European Room
- World Scenarios
- Futuristic Scenarios
Completing a scenario will award the player either a Bronze, Silver or Gold medal depending on which objectives are completed. All objectives need to be completed in a time limit to be awarded a medal. In general, you will want to get as much money as possible.
In addition to the campaign, there are also standalone scenarios. As with campaign scenarios, they also have performance based on objectives completed.
