Features:

• All-new graphics engine with full world shadows and per-pixel lighting
• Multiplayer
• Share your enthusiasm with other rail fans and combine your efforts with others to operate a working rail line!
• Our most accurate simulation yet with real time world physics and editing tools!
• Calculated at 30 times a second, our physics use a variety of configurable inputs such as engine powers, train weight and rolling resistance whilst taking into account factors like track gradient, curve resistance and track adhesion for each train car when accelerating or decelerating. The brand new real time physics editing tools allow players to tune physics 'on-the-fly' to take their simulation's performance even further.
• Brand-new Real-time Physics Editing tools enable users to enter known specifications to accurately monitor all the forces at work. Things like tractive effort, drawbar pull or brake pipe pressure can be monitored at a specific point along the train and input values adjusted "on-the-fly". By analysing and tuning performance without leaving the simulation, real-world train characteristics can be matched perfectly. (It's a bit like running a virtual dynamometer car).
• If physics aren't your thing, don't worry. You can leave the fine-tuning of your favourite locomotive's performance to the experts whilst still having the choice between 'Realistic Mode' or 'Easy Mode' driving options.
