A BNSF runthrough train to Provo, Utah (H DENPVO1 21A) rounds the small curve at "Cliff" (Pinecliffe) on the Union Pacific Moffat Tunnel Subdivision on July 21, 2013. The train had a small locomotive issue at CP Crescent but was able to fix it and get back on the move after the eastbound Amtrak California Zephyr passed them.
