UNSPSC 41112807: Rail sleeper holding force measuring instrument

An instrument that is designed to measure the external force acting on the upper part of the railroad ties when the train passes by. The running rail is installed on the upper part of the railroad tie and is joined with the spike, bolt, nut and others for its fixation.

UNSPSC 41112807 Rail sleeper holding force measuring instrument is a Commodity code that encompasses diagnostic and measurement equipment used to assess the structural integrity and load-bearing capacity of railroad track components, particularly rail sleepers (crossties) and their fastening systems. State and local governments procure under this code primarily through transit authorities and municipal utilities responsible for freight or commuter rail infrastructure. The work involves both the acquisition of specialized testing instruments and the related inspection and maintenance services that depend on such equipment to ensure track safety and compliance with rail system standards.

Transit authorities dominate recent solicitation activity under this code. Charlotte Area Transit System (CATS) issued RFP 26920272117 for CATS IV Streetcar Truck Overhauls, due October 20, 2026, which encompasses comprehensive overhaul of truck, hydraulic, and braking systems on Siemens vehicles at OEM-specified intervals. The City of Dallas posted ID/IQ service agreement BTZ2600031254 on October 8, 2026, due November 13, 2026, for a thirty-six-month track inspection and maintenance program covering railroad spur track repair and assessment. Activity is concentrated in the South and Southwest, with Texas and North Carolina representing the two recent sources. The code shows limited recent activity overall, and the opportunities posted reflect asset-preservation work on existing rail infrastructure rather than discrete procurement of measurement instruments alone, suggesting that rail sleeper testing equipment may be sourced as part of broader track maintenance contracts or through cooperative purchasing arrangements rather than as standalone commodity acquisitions.
