I got a call for the "D NEESBD." My engineer and I were to take 5 motors out of Roundhouse 2 and 1 and bring them to Barstow. From there they would go on to San Bernadino. There was another crew taking some engines out of the Roundhouse that were to go to Winslow. We would have to stay out of each otgher's way. Fortunately our move was rather simple. We would have to back 3 of the motors out of Roundhouse 2 and then couple them to the other two motors on Roundhouse 1. My engineer started to release the handbrakes on the frist 3 motors, which were coupled together. To my horror they started to roll! If they kept rolling they would sideswipe another engine. I yelled, "They're rolling, stop!" and he did. The independant brakes weren't set. He started them up and released the handbrake. I worked the switches and guided him to a hook Once we had the hoses laced, we did the "Locomotive Air Brake Test." Our consist was ready to go in 2 hours and 20 minutes. Not bad. The dispatcher let us out of the yard. I only had to thorw one switch behind us as we left. :"Light Power," as we call it can go passenger train speed. But we had a throttle restriction of 5. Nonetheless, we made it to Barstow in about 5 hours. They brought us into the Rio Seco track. Since we were power only we could not tie our consist down. We would have to wait to be relieved. (Engines can not be left unattended unless they are coupled to a car, or unless there is a derail). The router told us that our outbound would be on duty in an hour. WE WAITED 3 HOURS TO BE RELIEVED. We had been on duty for over 10 hours. We tied up, went to the hotel, and I had a good breakfast. I slept for about 4 hours, went to get something to eat, and went back to bed for another 4 hours. I got my call at 10:35 pm. I was called for the Q LACATG. On duty time was 5 minutes after midnight. We got on at the steps. Our train had 4 motors on the head end. The second one was isolated and we cut out the dynamic brakes. It was a routine trip- until we got to Needles. As we were pulling into the yard I saw what I thought were fireworks behind me. I turned around and through the back window I cold see sparks and flames coming out of the compartment behind me. I told my engineer. He decreased the dynamic brakes and the sparks decreased. He increased them and the sparks increased. (This compartment had something to do with the dynamic brakes). There was another train coming in next ot us and they saw the flames too. We reported it to the dispatcher. and our outbound of course. After some consultation, and afer the flames subsided they decided to take the train,. They would isolate the lead motor and cut out the dynamic brakes. They brought the second motor online. I have attached a pic ture of our motor. You can see some smoke coming from the other side. I'm projected go out in the morning, but since New Year's Eve is coming up I'm sure some guys will lay off and I will go out much earlier. HAVE A HAPPY NEW YEAR!
