Project Description 

RailWorks provided track, traction power, signal/communications and facility construction services to expand the light rail line at Fairview Heights to accommodate additional rail capacity.

Project Scope 

This expansive $10 million project featured constructing a “pocket track” between the east and westbound tracks to improve and expand passenger service limits in Metro's core system. The expansion allowed Metro to maximize capacity during peak commuter times and special events, such as St. Louis Cardinal games. The project required constructing an 11,000–foot new concrete tie track and a 200-foot wood tie maintenance spur and installing six turnouts.

RailWorks constructed a total of 1500 track feet of new track and six turnouts, perrformed grading and drainage, including a box culvert extension and other required civil work. L.K. Comstock worked as a subcontractor to install OCS (overhead catenary system) modifications and perform signals and communications.

Unique Features 

RailWorks performed the complex phased work under traffic and with minimal work windows in just 11 months. Prior to construction Metro traveled another 14 miles to turn the train at the end of the alignment.
