I got called for a Z train going to Barstow. On duty time was 4:30 pm. It was a good train. They ran us like a Z. We got in around 11 pm and were relieved by the outbound on Main 4. I slept pretty good, got up for the free breakfast at 6 am, and went back to bed. The wifi in the hotel wasn't working very well, so I couldn't log into the workforce hub. I wondered when I was going to be called. I slept most of the day. When I was finally able to log in I saw that I was projected for a stack train around 7:45 pm, so I got up and got ready even though I hadn't been called. I was headed out to catch the van when I did get my call. I got a burrito from Lola's on the way. There was a stack train at the steps that came in before our train. A crew had not been called for it. At the last minute they swapped my engineer and I to that train. We got on at the steps. The trip started out slowly because we had to wait for Amtrak to go by. It was a good trip. There wasn't a lot of traffic. As we got close to Needles I looked in my IPAD and it said that we had to set out our 4th motor. They brought us into the yard. I had to throw two switches to line us into Yard 2. Whe we got to the east end of the yard the outbound was waiting for us. They helped us do the set out and it went very quickly. The dispatcher had told us to put it in Roundhouse 3. I had to throw one switch to line us in. I'm projected for a vehicle train around 6 pm tonight.
