MRS was part of the design/build team that designed, furnished, and installed the signal & train control system for the Utah Transit Authority Draper Light Rail Transit Extension Project in Salt Lake City. MRS performed this work with our subcontractor, MJG, Inc.
The Draper TRAX Line was created to address the community’s growing population. The transportation needs of residents and commuters in the southeast part of the Salt Lake Valley will eventually exceed the capacity of existing transportation choices. Both population and employment growth are predicted to be significant, as are changes to land-use patterns. Once a quiet farming community, Draper is a growing and dynamic community of nearly 45,000 people with an increasingly important high-tech sector.
The 3.8 mile extension runs from the Sandy Civic Center Station to the new Draper Town Center Station. It is the final segment of UTA’s FrontLines 2015 Project, which has added more than 70 miles of new rail lines and was completed two years early and $300 million under budget. Revenue service began on Sunday, Aug. 18, 2013.
The Draper extension consists of a single ballasted interlocking, 11 grade crossings and three new passenger stations. Draper required an unusual design in that the railway is shared by both light rail as well as freight service. On the construction side of the project, additional care was required in order to maintain freight service on the existing right-of-way. We had no occurrences or injuries in this active right of way; once again proving our extensive detail to safety.
This line tie’s into the existing 10000 South TRAX station and ends near City Hall in Draper. The maximum operating speed on the line is 65 mph normal running for the light rail vehicles and 35 mph for freight and maintenance-of-way operations. Reverse running is designed for a maximum speed of 35 mph for all vehicles.
