Thanks for the link to your blog and the excellent write up about route cards. If you are of a mind to do so - you might add a bit of coverage about the tack boards on the ends of cars and when they were used (and not?) and for want.
Question - some one mentioned hazard placarding. Wasn't it relatively rare for hazardous loads to be transported in any type of car other than tanks - or is it just so much more common in tanks that we don't see the hazard placarding on other car types? Would hazardous materials that were shipped in box cars have tended in cars that were in captive service?
Is the topic of hazardous placarding worthy of another page in your excellent blog (or does it already exist)? I know that the placards and practices relating to them went thru some significant changes over the years - usually in broad sweeping changes that happened "all at once" from time to time when the government saw a need to revisit the topic. - Jim
