NIGP 55820: Freight Cars

NIGP 55820 Freight Cars, an Item code, covers overhaul, repair, and maintenance work on transit rail vehicles, specifically streetcars and light-rail truck assemblies. State and local governments buying under this code solicit specialized mechanical work on transit-fleet components — truck frames, hydraulic systems, braking assemblies, axles, wheelsets, and journal bearings — typically to meet original equipment manufacturer maintenance intervals and extend vehicle service life. The work is narrow and specialized, concentrated among transit authorities that operate rail fleets and require vendor shops capable of performing OEM-specification overhauls on proprietary systems like Siemens streetcar trucks.

Charlotte Area Transit System (CATS) posted an RFP (#26920272117) on August 18, 2026, with a response date of October 20, 2026, for CATS IV Streetcar Truck Overhauls, encompassing truck, hydraulic, and braking system overhauls on Siemens trucks at fifteen-year / 270,000-mile intervals, plus low-floor axles and wheelsets at 300,000-mile intervals and journal bearing equipment at six-year / 310,000-mile intervals. The vendor must perform maintenance to OEM specifications, with CATS's Reliability, Condition & Maintenance department removing and preparing equipment for shipment and the Rail Inventory department coordinating transport. No contract value or incumbent vendor information is disclosed. Recent activity under this code appears limited to transit authorities with active rail vehicle fleets requiring specialized overhaul capability; broader market signals for the code are not supported by the source.
