The Union Pacific/General Electric Green Locomotive Technology Tour has just arrived in Los Angeles. I had just missed shooting it on the road in Glendale by seconds (I got there too late), and by the time I caught up with it, it was parked at LAUPT. The four engines consist of #7606 a brand new (2/13/07) ES44AC, General Electric #7605 (2/13/07), UP #Y2701, the first of NRE's 3GS21Bs (12/06), UP #Y1378 - the MP15-DPF with a HUG Particle Filter (nicknamed the Pizza Oven), and UP #2368, the Oxicat SD60M.
