S1532

S.1532 was introduced on April 30, 2025 by Senator Crapo (R-ID) and Senator Wyden (D-OR), and referred to the Senate Committee on Finance. The bill amends Section 45G of the Internal Revenue Code to increase the per-mile tax credit limit from $3,500 to $6,100, indexed for inflation starting in 2025. The legislation also expands eligibility by updating the base year for qualified expenditures from 2015 to 2024. The bill is an authorization of a tax credit — it does not directly appropriate funds but reduces federal tax revenue by the amount of credits claimed. The Joint Committee on Taxation would estimate the revenue cost; based on prior extensions, the annual cost is in the hundreds of millions. The structural winners are suppliers to the short-line rail maintenance ecosystem. The Greenbrier Companies (GBX) manufactures railcars and provides maintenance services; higher maintenance spending increases demand for railcar repair, refurbishment, and new rolling stock. Westinghouse Air Brake (WAB) provides braking systems, track components, and maintenance equipment; its aftermarket parts business benefits directly. Class I railroads like UNP, CSX, and NSC benefit indirectly from improved feeder network reliability but see minimal direct revenue impact since the credit is not available to them. Market data shows GBX is down 2.86% in the 7-day period and down 9.06% over the 30-day period, trading at $47.88 near the lower end of its 52-week range ($38.23–$59.19). WAB is down 0.91% over 7 days but up 5.89% over 30 days, trading at $264.62 near the top of its 52-week range ($183.98–$275.84). The legislation's introduction has not yet moved either stock, consistent with its early-stage status. The bill requires passage through the Finance Committee, full Senate vote, House action on HR516, and Presidential signature — a timeline likely spanning the remainder of the 119th Congress.
