UNSPSC 25171907: Railway sander support or base

Device to hold railway sander

UNSPSC 25171907 Railway sander support or base (Commodity) describes light mechanical and structural components for light rail vehicle (LRV) maintenance and repair, with recent state and local activity dominated by Dallas Area Rapid Transit Authority's component procurement through tactical purchase orders. DART solicits parts including carbide inserts for LRV wheel machines, shock absorbers for trucks (center and end), non-magnetic spacers, connecting links, wear rings, hose assemblies for air motor truck bolsters, pole end pieces, rod ends for leveling valves, safety bars with oak and stainless steel end plates, tire kits, gaskets, O-rings, bearing radius rod assemblies, external shunts, idler speed sensor rings, seat airbag diaphragms, and air spring diaphragms. The issuing body is almost entirely a single repeat buyer—Dallas Area Rapid Transit Authority, a transit authority in Texas—with one outlier solicitation from Maine Department of Transportation (MDOT) for rail stock, joint bars, track bolts, tie plates, track spikes, rail anchors, and cross ties. DART procures these components through competitive purchase orders posted to its BONFIRE platform, requiring FOB Destination pricing with freight included, Net 30 payment terms, invoices submitted in triplicate to APInvoices@dart.org, and strict adherence to delivery schedules with failure to perform constituting grounds for default termination.

Recent activity concentrates in Texas, with DART issuing at least sixteen solicitations between February and July 2026, all for Dallas County delivery. Geographic spread beyond Texas is minimal; the Maine RFQ (Request for Quotation 17A 26031-223 by MDOT, posted 24 March 2026, due 1 April 2026) represents the only recent state activity outside Texas and sought rail materials including 115 RE rail stock, joint bars, and treated cross ties to multiple Maine locations. DART's procurement rhythm is steady and tactical—individual component bids posted weekly with response windows of five to seven days (for example, carbide inserts for LRV wheel machine use, posted 13 July 2026, due 20 July 2026; shock absorber center truck, posted 2 July 2026, due 9 July 2026). One peripheral solicitation—Donna ISD's general hardware and lumber supplies catalog bid (RFP 011326-874, posted 21 March 2026, due 8 April 2026)—was tagged to this code but shows minimal relevance, as the district sought broad discount proposals on catalog items rather than railway-specific components. The code sees active, recurring demand but is narrowly concentrated in a single transit authority's maintenance supply chain.
