Spirit Rail Visits Second Life

I spent a number of hours learning the 3D design tools in Second Life. A friend of mine has two patents on a light rail system named "Spirit Rail" and, after having modeled it in Maya last year, I thought I would try modeling it in the virtual world. Now for scripting it to open doors and move down it's track! Can anyone say "virtual, interactive presentations in real time"? (Click the images to enlarge.)
