Hello As i mentioned in the last of U-Boat thread about the next project. I would like to introduce "UNION PACIFIC BIG BOY 4-8-8-4" in 1/48 scale. The model length is 870 mm (34 inch) include tender. BIG BOY is known as the largest steam engine , weight of 500 ton , 120 km/hr maximum speed. This machine is very impressive. I wish to put as much details as paper can do. Internal links , suspensions , brake system will be added. The model is designed based on original drawings from "Union Pacific"(30us$ in CD format). 3600 drawings are contained in CD. The drawings were drawn since 1939. No layer separation as todays' CAD drawing. I took very long time to get understand with some drawings. Same as U-Boat , I'll design and build then report the progression. This project prototype building will be in color version. I started to draw 3D 1 month ago. I try to put realistic machanism parts as much as i can understand the drawings. OK.... let see the starting of BIG BOY BIG BOY pic Start drawing from front engine Then fill more details to Engine Truck Addition suspension links.
