This is a 1:40 model of the Morgantown PRT. This system opened in the 1970's and was built by Boeing. It is the only system of its kind in the world. It transports students at West Virginia University between 5 different stations. The unique feature of this system is the offline nature of the stations - vehicles can travel directly from origin to destination, with no intermediate stops. Technically classified as "Group Rapid Transit", it continues to run to this day for just 50 cents per ride, or free to students. Photo of the actual system is from Wikipedia.Print each of the STL files. They can all be printed with no support. Glue the windows into the sockets of the vehicle body. Glue the guide wheel bars to the chassis bar, and glue the wheels onto the chassis (they are a press fit, so glue actually isn't required). Press 5 x 16mm dowel pins into the bottom of the vehicle body and it will snap onto the chassis.
