To amend the Internal Revenue Code of 1986 to modify the railroad track maintenance credit.

**What happened and its current status:** HR 516 was introduced on January 16, 2025 by Rep. Mike Kelly (R-PA) and referred to the House Committee on Ways and Means. The bill has an identical Senate companion (S1532) and 164 cosponsors, unusually strong support for early-stage legislation. The bill remains in committee with three actions logged (all from the same date), indicating early legislative stage but with substantial behind-the-scenes coalition building. **Money trail:** This is a tax credit bill, not an appropriation. The mechanism increases the per-mile limit on qualified railroad track maintenance expenses from $3,500 to $6,100 (74% increase), indexed to inflation after 2025. The effective date covers expenditures in tax years beginning after December 31, 2024, meaning companies could potentially claim the higher credit for the current tax year. The credit is non-refundable and applies against regular tax liability. Estimated value to Class I railroads: each could see $40-150 million annually in reduced tax liabilities depending on assigned track miles. **Structural winners and losers:** The primary direct beneficiaries are Class I railroads ($CSX, $UNP, $NSC) that have extensive short-line partner networks. Short-line operators ( subsidiary, $GBDC's rail leasing division) benefit indirectly through higher asset values and potentially better lease terms. No clear losers in this bill — it's a pure tax incentive that reduces costs for track maintenance. The Presidential Memorandum actions on coal, petroleum, and natural gas infrastructure (mentioned in the prompt as context) are unrelated to the tax credit mechanism and are not analyzed here. **Market data analysis:** Real market data shows all three Class I railroads up 9-10% over the past 30 days. CSX is at $44.89 (52-wk high $46.55), UNP at $266.08 (52-wk high $274.79), and NSC at $313.44 (52-wk high $323.37). All are trading within 3-4% of 52-week highs, suggesting market is already pricing in favorable legislative outcomes. The 7-day declines of 1-2% are minor pullbacks from recent peaks, not trend reversals. **Timeline:** The bill is early-stage (referred to committee). Path to passage requires: (1) House Ways and Means Committee mark-up, (2) House floor vote, (3) Senate Finance Committee mark-up, (4) Senate floor vote on companion bill S1532, (5) conference committee if differences exist, then (6) Presidential signature. Given 164 cosponsors and bipartisan support, odds of passage in the 119th Congress are above average for a tax bill. Expected timeline: mark-up in late 2025, potential inclusion in a larger tax extenders package.
