As evening descends over the Rocky Mountains with Union Pacific's Moffat Tunnel Subdivision therein, the rumble of a train can be heard through South Boulder Canyon as they work their way up the 2% grade into Pinecliffe, Colorado. Framed from atop tunnel 29, we see an empty UP westbound oil train pass the sight of the daylighted Tunnel 28 in the backdrop, then wrapping around the bend past the Boiling Gulch just before entering the east portal of the short Tunnel 29.
The roar of six locomotives working their train through some of the most impressive railroad engineering for its time, the sounds of the South Boulder Creek below and the cool evening air all from my vantage point overlooking the canyon was truly breathtaking and a mere image just cannot do justice.
