Project Description 

Union Pacific expanded its main line at Gasconade, Mo., to provide additional capacity.

Project Scope 

RailWorks furnished labor and equipment to construct 25,000 track feet for a second main line for Union Pacific.

Unique Features 

Several factors made this project uniquely challenging. The new line was built between the existing main line and the winding Missouri River, which severely limited access for material handling. The project called for installing new 141# rail on concrete ties using a newly designed rail clip specified by the railroad. This required using special equipment, which was under development by the manufacturer and tested on this job. The machine needed to be robust enough to push on and pull off the clips for construction and rail de-stressing.
