"You'll have a railroad company"
Railroad Tycoon II is a train simulator. You will become an important railway entrepreneur, you will have your own company and your mission will be to link the different cities by creating new routes and increasing the number of trains, machines and convoys available.
Don't think it's a simple task, all your journeys should be profitable, although some may be complicated and you can compensate with other lines that have more demand. The problem will not only be money but also managing all the timetables, ensuring that the trains comply with the route in the estimated time and that there is always a track available, especially in the stations for the passage of trains.
