UNSPSC 25121714: Heavy rail turnout switch

Turnout switch for heavy rail lines.

UNSPSC 25121714 Heavy rail turnout switch is a Commodity code covering rail infrastructure components and associated maintenance services that state and local transit authorities procure to sustain streetcar and light rail operations. Recent solicitations under this code show transit agencies buying overhaul and maintenance services for rail vehicle trucks, hydraulic systems, braking systems, and grade crossing control components — work performed to original equipment manufacturer specifications at defined maintenance intervals to extend fleet service life and ensure safety and reliability. Charlotte Area Transit System (CATS) has posted multiple opportunities recently, positioning it as an active buyer in this space. The work typically involves removing equipment, coordinating transport to specialized vendors, and performing system-level overhauls rather than replacing single components.

Activity concentrates in North Carolina, where CATS has posted two recent solicitations as of August 2026. CATS issued an RFP for CATS IV Streetcar Truck Overhauls (Solicitation 26920272117, due October 20, 2026) encompassing truck, hydraulic, and braking system overhauls on Siemens equipment at 15-year / 270,000-mile service intervals, with low-floor axles and wheelsets serviced at 300,000-mile intervals and journal bearing equipment at 6-year / 310,000-mile intervals. The same issuing body posted an IFB for Train Control Grade Crossing Spare Parts (Solicitation 26920272053, due September 14, 2026), though the source provides limited detail on specific components or pricing. No contract values or incumbent information is available in the public record.
