Model Asia Super Detailed China Rail C80 Coal Hoppers

These are from Model Asia, a relatively new, but extremely dedicated manufacturer of Chinese model railroad rolling stock and associated accessories. 

C80 coal hoppers hold 80 tons of Black Magic and were designed for modern, high-speed coal haulage. They are becoming more common as they start to take over from several of its predecessors, including the nearly ubiquitous C62. They're most accurately towed by more modern China Rail locomotives--particularly electric locomotives--but their striking appearance will look great running behind just about everything.
