After attending the "Great Train Show" model train expo in Sacramento, some friends and I decided to spend the afternoon railfanning Union Pacific's JR Davis Yard in Roseville. While traffic was light, the few trains we did see provided some interesting power with the highlights being a Kansas City Southern GEVO on the outbound MRVWC power, a pair of CSX leaders on a Goshen-bound loaded grain train, and an SD70AH-T4 on the rear of the IOANP intermodal train!
