Overview

• An early Sept. 21 rupture west of Cheyenne ignited a large fire south of I‑80 mile marker 345, according to Laramie County fire officials.
• The Union Pacific crew halted a freight train about 40 feet from the flames, freight cars were blackened, and no cars derailed.
• Responders had the blaze under control by midmorning with no injuries reported and no large hazardous-material releases to the public.
• Kinder Morgan’s Colorado Interstate Gas shut gas flow to the affected segment and began investigating the potential failure.
• The NTSB said investigators would be on scene Monday, and Union Pacific will inspect track conditions before moving the train; the glow and smoke were visible across northern Colorado.
