US freight locos are different, if only because US rail safety regulations until recently prioritized buff strength whereas European and Japanese regulations do not.
(Buff strength is a terrible way to maintain safety. We moved away from it in automobiles decades ago for a reason.)
- dsfyu404ed 4y agoYour comment reeks of typical internet crumple zone worship. You absolutely do need “buff strength” in the parts of a vehicle that hold the occupants. Cabins have only gotten stronger and more rigid with time.
- Panzer04 4y agoSeems like there'd be a big difference between a train with a thousand tons of carriages pushing it along (ie. Not Going To Stop) and a car that will stop, necessitating a crumple zone to drag that stop over the longest possible period.
- bobthepanda 4y agoIf you throw a steel box of eggs at the wall, the box will probably be fine, but not the eggs.
- Panzer04 4y agoRight - but in this case the steel box is 1000 ton and going straight through the wall, so it's not going to be stopping - in this case you want the steel box to protect the eggs, rather than splattering them by using a cardboard box (carrying on the analogy)
