>>1477003>Trucks climb 10% hills every single dayIt's not the going up that's the problem for the truck. It's the going back down. Enjoyed those burned out brakes and runaway big rigs. It's not uncommon on 5-7% grades in the American Rockies, let alone whatever 10% grade you're talking about.
>it's physically impossible for a train to do so.Incorrect, there are active rail lines that operate on grades like that without a rack or cable. That's besides the point though, because once again for rails it's cheaper and more efficient to tunnel or build a spiral incline to lessen the overall grade instead.
