B25OP04102 - INVITATION FOR BIDS (NON-NEGOTIABLE)- Switch Point/Stock Rail Combinations and Rail Bound Manganese Frogs for 36 Months with Two One-Year Options

The Regional Transportation Authority (RTA) of Chicago, which operates Metra commuter rail, is requesting bids on switch point/stock rail combinations and rail-bound manganese frogs under IFB B25OP04102, with bids due September 18, 2026.

The contract covers a 36-month base term with two one-year renewal options. Switch points and stock rails are critical trackwork components for rail switches; manganese frogs are wear-resistant cast components at the intersection of two rails. These are standardized heavy-rail replacement and maintenance parts subject to specific geometric, material, and performance tolerances typical of Class 1 railroad specifications.

The invitation is non-negotiable, meaning bid terms and pricing are fixed and not subject to post-award discussion or adjustment. This procurement structure is typical for commodity rail infrastructure components where specifications are mature and standardized.

No estimated contract value, incumbent contractor, evaluation criteria weighting, or pre-bid meeting is identified in the source. Questions due date, site visit, and specific technical material or performance standards are not provided.
