Trinity Railway Express (TRE) Commuter Rail System

The TRE Commuter Rail System extends along the existing 34-mile Rock Island Railroad corridor. Planning, development, and operation of the commuter rail service is jointly sponsored by Dallas Area Rapid Transit (DART) and FWTA. The initial 11-mile service between downtown Dallas and the City of Irving was planned and designed by Huitt-Zollars for DART. This starter system employs self-propelled DMV cars and has four stations. The FWTA retained Huitt-Zollars to plan and design a 24-mile extension from Irving to downtown Fort Worth. Huitt-Zollars was responsible for the design of Package 3 of Phase 2A, which extends 24 miles from south Irving to Fort Worth.
