UNSPSC 25121715: Light rail turnout switch

Turnout switch for light rail lines.

UNSPSC 25121715 Light rail turnout switch is a Commodity code covering spare parts, components, and maintenance support for rail transit switching and control infrastructure. State and local governments buying under this code procure replacement and repair items for light rail, streetcar, and commuter rail systems to maintain fleet reliability and service continuity. The issuing bodies are transit authorities operating fixed-guideway systems, typically regional or municipal transit agencies responsible for light rail or streetcar networks.

Charlotte Area Transit System (CATS) posted two recent opportunities in August 2026 that signal activity in this space: solicitation 26920272117 for CATS IV Streetcar Truck Overhauls (due October 20, 2026) and solicitation 26920272053 for Train Control Grade Crossing Spare Parts (due September 14, 2026). CATS is the primary recent buyer visible in the source material. The streetcar truck overhaul work involves overhauls of Siemens trucks at 15-year / 270,000-mile intervals plus low-floor axles, wheelsets, and journal bearing equipment at manufacturer-specified maintenance intervals; the scope also encompasses hydraulic and braking system overhauls to original equipment manufacturer specifications. The grade crossing spare parts opportunity is more narrowly defined in the available source but signals ongoing procurement of control system components. North Carolina, specifically the Charlotte metropolitan area, is the identifiable geographic center of recent UNSPSC 25121715 activity in the state and local market.
