While working in Beijing Trolleybus Building and Assembly Plant, another privilege is that I can have chance to view the blueprints and made 3-D models according to them offcially! This is a great honor to me indeed. And the above models are nearly zero difference from the real-world one. Before this, I have to estimate all the dimensions by comparing different photos at different angles. They are strictly confidential of course.They are still under "construction".
