NIGP 55925: Current Collecting Systems

NIGP 55925 Current Collecting Systems, an Item code, encompasses overhauls and maintenance of streetcar electrical and mechanical systems to original equipment manufacturer specifications, with state and local transit authorities as the primary buyers. The scope includes truck, hydraulic, braking system, axle, wheelset, and journal bearing overhauls on fixed-guideway transit vehicles, performed by specialized vendors to restore components to OEM standards and extend fleet service life. Work is solicited by transit authorities operating modern streetcar systems and maintaining aging rail fleets through condition-based maintenance intervals.

Charlotte Area Transit System (CATS) posted a solicitation in August 2026 (due October 20, 2026) for CATS IV Streetcar Truck Overhauls, seeking a vendor to overhaul 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. The vendor must perform all work to OEM specifications while CATS's Reliability, Condition & Maintenance and Rail Inventory departments manage equipment removal, preparation, and transport coordination. This represents the only recent opportunity identified under the code in the source material.
