A Utah Railway train of loaded oil and sulfuric acid tank cars heads west from the road's Martin Yard, in Helper, Utah, to Provo. The train is powered by MK50-3 5005, MK50-3 5006, SD50S 6060, SD50S 6064 and MK50-3 5003 - all exotic models! Winding through the S-curves at West Kyune, the Utah Railway train meets a Union Pacific eastbound, lead by UP AC4400CW 6415 (still in predecessor Southern Pacific colors).
