I just turned it off after a while. One of my all-time favorite games. The gaming parameters are changed to match the difficulty of runing a railroad profitable in the twentieth century. Build a railroad mastering construction, terrain, finance and competition. Play against a computer or online against others.
User interface is intuitive and clean with few annoyances.
Running track across rivers can be difficult and the lack of tunnels is a major pain. The use of simple sprites to animate the rolling stock reminds me of the Sid Meir's first railroad tycoon. Lots of context-specific sound effects. These can be annoying. The game is basically the same with some minor improvements.
