Been there, too, Earl. ---
I was trying to make that point, also ...... that the hand signals shown in GCOR and CCOR are just the basics ..... there were tons of others in use not so many years ago.
I got a train of empty coal cars stopped over in Utah once, just before the Soldier Summit grade began ..... was standing watching and they came around the curve with a bearing smoking badly .... (yes, it was a roller bearing) ..... fortunately Rio Grande still had waycars and the rear end crew saw my hotbox signal ... stopped, and set out the hopper.
