Near the east end of Leyden, an eastbound BNSF manifest is holding the main at Leyden. The exact reason for stopping was not apparent as the train had an Advanced Approach (flashing yellow) signal at the east end of Leyden. Meanwhile, a rather significant thunderstorm has formed over the Rockies and is moving out on to the plains in the distance.
For the train and storm chaser. Trains with thunderstorms, dark clouds, rain, lightning, hurricanes - tropical storms, funnel clouds, storm light, rainbows, and snow storms.
