#14 Deterioration of the Union Pacific Grade

Deterioration of the Union Pacific Grade

NPS/ncastoro

In late 1869, the Central Pacific assumed responsibility for the segment of railroad between Promontory and Ogden. The Union Pacific abandoned its grade, including the Big Trestle, and the grade built through this area by the Central Pacific became the main line for the next 36 years. Because it was no longer used, the Union Pacific grade deteriorated and is now much smaller than its counterpart. 

Deterioration of the grade is difficult to see in the photo below. During your walk, however, take time to notice the difference between the two grades.
