Union Pacific played a major part in the Dunsmuir RR Days this year. Not only did they bring a couple of their executive passenger cars, they also brought an example of their latest in switching technology. This locomotive is a hybrid running on batteries and a relatively small diesel engine to recharge the batteries. RailPower Technology remanufactures an older locomotive replacing the 12 or 16 cylider unit with a 6 cylinder in this unit. RailPower was nice enough to send their technician to show it off. I spent a good 20 minutes talking with him and he gave me a full tour including all the inner workings. Take a look at UPY 2004 inside and out!
