UP's North Platte-West Colton appears to be running away from a nasty storm system over Salt Lake City. The 7829 and company have 102 cars with a single ES44AC DPU on the rear of the train (UP 7858).
For the train and storm chaser. Trains with thunderstorms, dark clouds, rain, lightning, hurricanes - tropical storms, funnel clouds, storm light, rainbows, and snow storms.
