thinkSo here is the actual statistic not confused by fading memory, I still
it is impressive:
One can transport 1 ton of freight 100 km with 14 oz of diesel fuel, by
That is a really interesting combination of units. But what does it mean?
Is it the marginal fuel used to move that much cargo, over and above that
used just to get the locomotive and the railroad car there? Does it depend
on the length of the train? If I am hauling a fully loaded 150 car train
and add 1 ton to one of the cars, do I use 14 oz. more fuel per 100 km? Or
is it the total fuel to move the train per ton of cargo carried? This sound
impressive but it may be considerably less so when put in the context in
which it was derived.
