NIGP 55814: Car Dumper System Including Electronics and Controls

NIGP 55814 Car Dumper System Including Electronics and Controls is an Item code for specialized equipment systems and their integrated control components used in rail and transit applications. Based on recent state and local solicitation activity, this code encompasses traction power systems maintenance and repair work on light rail transit infrastructure, including overhead contact system repairs, substation maintenance, underground wire work, and catastrophic damage restoration. The Metropolitan Transit Authority of Harris County, Texas (METRO) represents the primary recent buyer in this space, soliciting comprehensive traction electrification systems services across its light rail network. Issuing bodies pursuing this work are typically regional transit authorities with significant capital assets in rail electrification; the code may also see activity from state departments of transportation and municipal transit agencies operating electrified rail corridors.

METRO's February 2026 RFP for Traction Power Services (RFPDOC1979592493, due March 4, 2026) exemplifies the scope: maintenance and repair work covering three light rail corridors (Red, Green, and Purple lines) totaling 23 miles of double track in the Houston metropolitan area. The solicitation targets contractors with a minimum of three years of traction electrification systems experience on U.S. light rail projects and requires a local presence in Houston. METRO is evaluating proposals on a 100-point scale covering work plan, quality control, firm qualifications, project experience, and pricing, with a three-year contract term plus two one-year option periods fully funded by federal dollars. The procurement carries no small business set-aside designation. Pre-proposal meetings and written questions deadlines occurred in early February 2026; proposals were due March 4, 2026. This remains the only recent state or local opportunity visible in the provided source material for this code.
