Placards

Hazardous materials placards with their UN numbers came in after the time frame for this group.

But was there a phase-out of other paper placards such as “Unload Other Side”, “Do Not Hump”, etc.?

At some point I’ve stop seeing these on photos of freight cars in years past.

Thanks.

I can answer having helped implement waybill systems on the Mopac in 1974.  The special instructions such as ‘do not hump’, ‘unload on right side’, etc were added to the computerized waybill and these notations were automatically added to switch lists and work orders.  Other Class 1’s were doing the same but I’m not sure of their timeframes but the mid to late 70’s would be a good guess.

Bob, you can still find both of those examples as stickers on modern day equipment.
