I got called for the Q CHISBD. On duty time was 9 pm. We had 4 motors on the head end and 1 on the rear. 2 of the motors on the head end were dead. Our HPT was only 1.5. When we got close to Barstow they told us we would be flipped. The brought us into Main 4 and told us "hold back, we will add another engine to the head end." I wasn't sure if he meant we were oging to add an engine to the head end, so I told him, "We will be DOL in 90 minutes." After a pause the router said the outbound would add the engine. I tied 3 brakes and it held. Our van showed up right away and took us to Needles. I'm projected to go out around 2 am. I barely slept yesterday and I'm tired. No pictures.
