Back at the CNW we had a couple of, shall we say, high-strung yardmasters. One of them was a pretty good guy who went from the ground to the tower, but I think the job was ruining him - they were always screwing him pretty good. Think I remember him pulling three shifts in a row once.
But we had this one guy. I'm usually pretty bad with names, but for some reason I remember his. He obtained the nickname "Screamer". He'd get on the radio and just rant and rave. One time we were piloting a Conrail crew into the yard. I don't remember what we did, it was a long time ago, but he didn't like a move we made so he goes off. Finally, after a minute or so, the Conrail Conductor gets on and tells him maybe, if he'd shut the h*** up for a minute, we could just finish our move and they could go home. This yardmaster actually pissed a guy from another road off so bad that, after heading back to his terminal and tying up, he came back to the tower and waited for him to come down so he could kick his a**. When the screamer came down, the Conductor asked, "are you so-and-so?"
"No, he's still upstairs", and he scurried off. Made things interesting for the poor guy who was still up in the tower when he came down!
