> Assume a train is going 100km/h That's quite an assumption. Yeah, that might be a reasonable (if brisk) cruising speed, but the average is probably gonna be a fair bit slower than that, especially when passing through cities or mountains. > 6m shipping container, let's say 7m, so 4 every second. Technically 8 (under the above assumption), since containers can double-stack (though not all tunnels offer enough clearance for it). Still, real-life throughput's usually gonna be a lot lower than this theoretical maximum (by at least an order of magnitude, if not more), namely because trains can't really be packed end-to-end on a track when moving at any useful speed; they ain't exactly able to stop on a dime, so for safety reasons there's gonna be a fair bit of distance between trains. Further, if you're going to count the time it takes for ports to load/unload containers, then it's only fair to do the same for train depots.
