NIGP 55948: Hubodometers, Rail Car

NIGP 55948 Hubodometers, Rail Car is an Item code under which state and local transit authorities procure specialized maintenance and overhaul services for rail vehicle measurement and monitoring equipment, specifically odometer and mileage-tracking systems that trigger preventive maintenance intervals on streetcars and light-rail fleets. The work involves removing, refurbishing, and reinstalling hubodometers and associated truck components—hydraulic systems, braking assemblies, and wheelsets—according to original equipment manufacturer specifications and maintenance schedules. Transit authorities use this code to ensure fleet vehicles reach end-of-useful-life through condition-based maintenance tied to accumulated mileage and service hours.

Charlotte Area Transit System (CATS) posted a representative solicitation on August 18, 2026, for CATS IV Streetcar Truck Overhauls, with proposals due October 20, 2026. The scope calls for overhauls of 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, all performed to OEM standards. CATS's Reliability, Condition & Maintenance department removes and prepares equipment; the Rail Inventory department coordinates transport to the selected vendor. No contract value or term is disclosed in the source. The solicitation activity is concentrated in transit authorities rather than general state or local agencies, suggesting the code serves a narrow but recurring maintenance function within regional transit systems pursuing fleet reliability and safety objectives.
