Saturday afternoon I was waiting to be called for a train when I got a call for "special work." A call for special work is a call for a job you normally don't get, and you can refuse it without getting into trouble. In this case it was a Z train going to Winslow. How could I turn that down? So I accepted it. It was the Z SBDALT. On duty time was 4:20 pm. They didn't run us like a Z train. It was a 10 hour trip. I got to Winslow after 2 am.I was exhausted after being awake all day. I slept for a couple of hours, got up for breakfast at 6 am, and slept until 5 pm. I got up and went down to the grill. I had a bandit burger. They were out of potoato chips so I had salsa chips. I got a call for another Z train going back to Needles. Our train was over 8500 feet and we had only head end power- so we were limited to 55 MPH- unusual for a Z train. On duty time was 9 pm. Our leader was a CSX engine but it wasn't bad for a CSX engine.We got to Needles around 6 am. I got home around 7 am and I went to Las Vegas to work on my next CD. I had no trouble staying awake even though I had been up all night. I slept good that night. The trip back was my 7th start, so I have 72 hours due to RISA.
