NIGP 55837: Monorail System, Accessories, and Parts

NIGP 55837 Monorail System, Accessories, and Parts is an Item code under which state and local transit authorities procure evaluation units, replacement components, and specialized maintenance services for modern streetcar and monorail fleets. Recent solicitations show that the code captures both capital acquisition of proprietary systems and vendor-performed overhauls of Siemens-manufactured trucks and related assemblies at OEM-specified maintenance intervals. Issuing bodies under this code are regional transit authorities managing light-rail and streetcar operations; the two recent opportunities come from Dallas Area Rapid Transit Authority (DART) and Charlotte Area Transit System (CATS), both procuring Siemens-based fleet components and services.

DART issued a bid request (REQ2100471) for a Siemens Trip Stop System evaluation unit with responses due October 9, 2026, subject to FOB Destination freight terms, Net 30 payment, and strict delivery-schedule requirements. CATS issued a competitive proposal opportunity (26920272117) for overhaul of CATS IV Streetcar trucks—including truck, hydraulic, and braking system work on Siemens trucks and related low-floor axles, wheelsets, and journal bearing equipment—with proposals due October 20, 2026. Both solicitations reflect operational maintenance cycles tied to original equipment manufacturer intervals, with CATS coordinating equipment removal and transport through its Reliability, Condition & Maintenance and Rail Inventory departments. Recent activity concentrates in Texas and North Carolina transit systems.
