With their DPUs just coming into the frame far left near the famed Hill 582, an eastbound BNSF stack train works up Main 1 as it moves through the control point at Silverwood.

For the train and storm chaser. Trains with thunderstorms, dark clouds, rain, lightning, hurricanes - tropical storms, funnel clouds, storm light, rainbows, and snow storms.
