Project Description 

DART's $188 million Blue Line expansion added 4.5 miles to the light rail line to link the downtowns of Garland and Rowlett, Texas. RailWorks companies, L.K. Comstock and RailWorks Track Systems began work on the project in February 2009. The project concluded in December 2012.

Project Scope 

L.K. Comstock designed and installed the traction power, overhead catenary, signaling, communication, visual displays, and public address systems. The signal system included a cab signaling feature with an operator decision support component that automatically adjusts train speeds in response to signals along the route.

RailWorks Track Systems constructed 4.8 miles of ballasted and direct fixation track. The projects featured installing track on four bridges, including two with direct fixation, one over the Kansas City Southern rail line at Garland and the other over Rowlett Creek.
