NIGP 55835: Locomotives, Electric

NIGP 55835 Locomotives, Electric is an Item code covering specialized overhaul and modernization services for commuter rail and streetcar propulsion and climate-control systems. State and local transit authorities are actively procuring truck overhauls following original equipment manufacturer maintenance intervals, HVAC unit restoration and refrigerant conversion on bi-level passenger rail vehicles, and passenger door modernization on rolling stock. The work involves removal, refurbishment, testing, documentation, and reinstallation of major vehicle subsystems to restore equipment to like-new condition and extend service life. Issuing bodies include regional transit authorities (Charlotte Area Transit System, Utah Transit Authority) and state transportation departments (State of Utah) pursuing multi-year fleet reliability initiatives.

Activity concentrates in the Upper South and West. Charlotte Area Transit System posted a proposal request for CATS IV Streetcar Truck Overhauls (Solicitation 26920272117, due October 20, 2026) covering truck, hydraulic, and braking system overhauls on Siemens equipment at OEM-specified intervals. Utah Transit Authority issued an RFP (Solicitation 2604043TD, due May 25, 2026) for Bombardier Bi-Level HVAC Unit Overhaul and Modernization on 38 commuter rail vehicles with 82 total units, requiring conversion to R-407C refrigerant and modernized microprocessor controls, with a contract term through December 31, 2030 and pilot installations on two vehicle series as qualification gates. The State of Utah posted an exploratory RFI (Solicitation 2604054TD, due September 9, 2026) on Bombardier Bi-Level Passenger Door Overhaul and Modernization to inform whether to proceed with a formal solicitation. Best-value evaluation methodology and phased pilot-installation approval gates are common in recent opportunities; no set-aside or MBE/DBE restrictions appear in current solicitations.
