NIGP 55850: Passenger Cars, Heavy (Self-Propelled)

NIGP 55850 Passenger Cars, Heavy (Self-Propelled), an Item code, encompasses the acquisition and maintenance of heavy passenger vehicles used by transit authorities. Based on recent state and local solicitations, the code covers major component overhauls and rebuild work on transit fleet assets, particularly streetcars and light-rail vehicles where specialized maintenance extends service life and ensures safety-critical performance across braking, hydraulic, and drivetrain systems. State and local transit authorities issue solicitations under this code when scheduled OEM maintenance intervals require specialized rebuild work beyond routine service.

Charlotte Area Transit System posted a representative opportunity in August 2026 (solicitation 26920272117) for CATS IV Streetcar Truck Overhauls, with proposals due October 20, 2026. The scope requires overhaul of Siemens truck systems, low-floor axles, wheelsets, and journal bearing equipment to OEM specifications and maintenance intervals (trucks at 15 years / 270,000 miles; axles and wheelsets at 300,000 miles; journal bearings at 6 years / 310,000 miles). CATS's Reliability, Condition & Maintenance department handles equipment removal and shipment preparation, with the Rail Inventory department coordinating transport to the selected vendor. The contracted vendor performs all maintenance work to OEM standards with the objective of sustaining fleet reliability, safety, and on-time service through vehicle end of useful life. No contract value or incumbent data is provided in the source.
