Train Fever is a railroad-focused business simulation game. In other words, it's a modern-day Transport Tycoon with procedural content and a sophisticated city simulation. 

"It’s the year 1850, and there are great times ahead! Establish a transport company and be its manager. Build infrastructure such as railways and stations, purchase transportation vehicles and manage lines. Fulfill the people’s needs and watch cities evolve dynamically. 

Train Fever runs on an engine specifically developed for this game. The engine has a great innovative scope and is specialized in procedural content and urban simulation. A key point is the fact that there is no grid that game objects have to be aligned to, allowing for a great degree of freedom.

Randomly generated, modifiable terrain with realistic dimensions
