| Union Pacific ES44AC #8021 leads the Global 2, IL to Oakland Z-train (ZG2OA) through Martinez. The ZG2OA is the result of a new operating code saying that the Global 2, IL to Lathrop Z-train (ZG2LT) will be split in Sparks, NV and one piece will go to Oakland while the other piece will continue on to Lathrop. |
