UNSPSC 25121707: Bogie assemblies

UNSPSC 25121707 Bogie assemblies is a Commodity code covering the overhaul, refurbishment, and maintenance of streetcar and transit vehicle truck assemblies — the wheel and suspension systems that support vehicle bodies and enable safe operation over extended service intervals. State and local governments, primarily transit authorities, solicit overhaul work on this code when their fleets reach original equipment manufacturer maintenance thresholds. Charlotte Area Transit System (CATS) is the issuing body represented in recent activity, seeking vendors to perform truck, hydraulic, and braking system overhauls on Siemens streetcar platforms at prescribed intervals — Siemens trucks at 15-year / 270,000-mile intervals, low-floor axles and wheelsets at 300,000-mile intervals, and journal bearing equipment at 6-year / 310,000-mile intervals. Work requires strict adherence to OEM specifications and standards to sustain fleet reliability, safety, and on-time service through the vehicles' end of useful life.

CATS posted a single recent opportunity — RFP 26920272117 for CATS IV Streetcar Truck Overhauls, posted August 18, 2026, with proposals due October 20, 2026. The scope spans truck, hydraulic, and braking system overhauls on Siemens platforms, with CATS's Reliability, Condition & Maintenance department handling equipment removal and preparation, and the Rail Inventory department coordinating transport to the selected vendor. No contract value or incumbent information is disclosed in the source. Transit authorities in major urban centers with streetcar or light-rail fleets represent the primary buyer pool for this code, with activity concentrated where legacy streetcar systems operate on defined maintenance cycles.
