Re: Tank Car Safety Appliances


Well this is not really steam era, but per AAR, they became mandatory for new
cars sometime around 1978 or so. Prior to that, I don't know when they
started putting them on but I would surprised if it was much before the
1970s. There was also a retrofit program that required most cars to receive
bottom-fitting program by sometime in the 1990s.

Trivia question: When did tank car companies
start applying the pieces of angled steel on
both sides of tank car outlet pipes to prevent
their being wiped off in a derailment?
