I didn't know that - it's surprising actually, given the distances over
which freight can be hauled in the US. I know the trains can be extremely
long, and it's an old movie cliché for escaped convicts with their legs
chained together to still be able to jump on a moving train, but I had
assumed the trains do get up a reasonable amount of speed. Articulated
lorries (trucks) use some aerodynamic features (like an air dam on the roof
ahead of a container) even if they rarely have a chance to get up to 70mph.
I suppose it's not as big a consideration as the drag from a great line of
rolling stock though.
