comment Are Zeppelins still not feasible?
@Master Of Disaster: isn't taking off and landing done by pumping in/out of air from the balloon? is pumping that much energy consuming?

of course, time is important. what i thought was perhaps they could have been employed instead of trains (not TGV, shinkansen or alike), as i think it could have been cheaper to maintain. apparently this is not the case, if it was they already would.

comment Grip of the train wheels
so, to sum it up: it is because of the weight of the whole train provides sufficient friction and steel-to-steel friction coefficient is also actually sufficient (not 'slippery' as i thought). did i get that correctly?

what's the right term then? i meant "not flexible" relative to a tire.
