Do you have or know where to find a bill of materials for these high-speed rail lines, as in how much steel and concrete is required per km of route, for bridges, for tunnels, steel for stations, etc. And, steel, aluminum, etc for the train sets?
The materials needed in a train also differ from model to model. But steel used to be most of it weight-wise, and 1 ton per passenger seat is a rule-of-thumb figure for a European train. (Now significantly lower for the AGV -- while the wider Japanese Shinkansens were always lower.) *Lunatic*, n. One whose delusions are out of fashion.
