This is an alpha version and it's directed to people that will try to help me on developing this addon. It worked correctly in two machines I could test but due to the 'boldness' of the project on pushing Orbiter large base quantities handling envelop and presuming compatibility of the railing Lua script with the frame rate extension that can be found in the user field I really can't assure this will work fine with your system and it can be boring , to say the least, to uninstall all meshes and textures.
For those brave that are still willing to download and install it I can say that the package contains 420 bases in the Moon that connect  the  UMMU 2.0 Demo Base and  the Brighton Beach Base with a more than 2000 km straight rail line. There are six stations along the route, one of them underground.
Included Lua scripts provide a way to keep the consist railed in the dispatcher assigned path and exhibit cab signals and messages. Routes, signals and messages can be setup by the advanced user using notepad.
