Description: Build and operate the railroad of your dreams. Trainz Simulator 2009: World Builder Edition includes everything you need to build and operate your own dream railroad. You can build a fun layout in minutes, faithfully recreate a steam railroad from days gone by or develop a fully fledged 100+ mile prototypical route; the choice is yours. As Engineer, you can climb inside the 3D cab and take charge of a wide range of diesel, electric or steam engines. Using Driver Commands, you can operate multiple trains by setting orders for computer AI Drivers to follow. Using Rules you can set up Driver Sessions, and give instructions for other Trainz fans to follow.
