UNSPSC 41112806: Rail joint gap measuring instrument

A type of device that is designed to measure the rail temperature and the gap of joint parts at the time of having the interval to the joint of rail. It occurs when the running rail is expanded and contracted in length direction in accordance with the temperature changes. It may deform 2-way direction or 1-way direction depending on each case.

UNSPSC 41112806 Rail joint gap measuring instrument is a Commodity code under which state and local governments procure inspection and measurement services for rail infrastructure, including track condition assessment, joint gap measurement, and related diagnostics to support maintenance and repair planning on railroad spurs and transit rail systems. The issuing bodies are transit authorities and municipal departments with direct rail operations or oversight—specifically, municipal transit agencies managing streetcar fleets and city departments responsible for railroad spur track systems. The work involves both routine condition monitoring and specialized overhaul coordination to meet original equipment manufacturer maintenance intervals and safety standards.

Recent activity centers on Texas and North Carolina. The City of Dallas posted an RFQ on October 8, 2026 (BTZ2600031254) soliciting a thirty-six-month ID/IQ service price agreement for track inspections and maintenance and repairs of its railroad spur track system, with proposals due November 13, 2026. Charlotte Area Transit System (CATS) posted an RFQ on August 18, 2026 (26920272117) seeking proposals for overhauls of CATS IV Streetcar trucks, including truck, hydraulic, and braking system overhauls on Siemens trucks following OEM recommendations at specified maintenance intervals (15-year / 270,000-mile for Siemens trucks, 300,000-mile for low-floor axles and wheelsets, 6-year / 310,000-mile for journal bearing equipment), with proposals due October 20, 2026. Both solicitations emphasize adherence to OEM specifications and standards to sustain fleet reliability and safety through end of useful life.
