Request for Information - TRAX Light Rail Signaling and Train Control Modernization Industry Outreach

The Utah Transit Authority is issuing RFI 26-04075 to gather industry input on modernizing the legacy train control system for its TRAX light rail, with questions due November 25, 2026 and responses due December 23, 2026 at 5:00 p.m. local time through the Euna portal. This is a non-binding market research tool, not a solicitation: it creates no contract, no commitment to issue an RFP, and no award, and UTA will assign no scores or ratings to responses. No set-aside or preference applies.

Input is sought on signaling and train control, communications systems, operations and maintenance, onboard equipment, back office systems, and cybersecurity, along with lessons learned on freight operations under a federally approved temporal separation waiver that allows freight trains exclusive overnight windows on shared alignment. UTA's stated objectives are signal compliance, speed enforcement, collision prevention, and work zone protection, reducing reliance on operator compliance with wayside signals and posted speeds. The system spans three light rail lines (Blue, Green, and Red) covering 45.3 route miles and 52 stations, with 73 Siemens S70 and 40 Siemens SD100/160 vehicles. Place of performance is in Salt Lake County and Salt Lake City.

Respondents must sign a one-way non-disclosure agreement before reviewing UTA's existing train control, communications, back-office, and traction power systems. The NDA limits use of disclosed information to preparing RFI responses, requires safeguards and prompt notice of any security incident, and runs five years from disclosure. Pricing is restricted to general cost estimates, ballpark figures, or standard pricing history; detailed or customized pricing is prohibited. UTA may conduct interviews or presentations to clarify responses. An optional informational meeting may be held, with date and location to be determined.
