Draper LRT Revenue Service

MRS was part of the design/build team that designed, furnished, and installed the signal & train control system for the Utah Transit Agency 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.
