Players will navigate through historical scenarios, optimizing the transportation of goods and passengers while competing against rival tycoons. The game features over 40 detailed locomotives and more than 30 wagons, allowing for strategic deployment based on their unique strengths and weaknesses. As players progress through five technological eras, they can invest in more than 300 technologies to enhance their operations.

The Nintendo Switch edition also includes additional content, such as scenarios in Mexico, The Great Lakes, and Crossing the Andes, along with new soundtracks and gameplay modes.
