Railroad retirement runs on Social Security's money and a workforce that's 87% gone

Railroad workers have never been in Social Security.▸ Since 1937 they've run their own parallel retirement system, financed by their own payroll taxes, paid out by their own agency, the Railroad Retirement Board. That independence was always a fiction of accounting more than of money — and in fiscal 2024 the fiction showed. The workforce that funds the system has collapsed for eighty years running, the checks now lean on a subsidy from the system railroaders were supposedly kept separate from, and the agency answering the phones has quietly admitted it can no longer do the job on time.

Railroad retirement is funded by a stack of Tier I and Tier II payroll taxes, plus a decades-old arrangement called the financial interchange: each year, Social Security's trust funds send the railroad system the extra benefits Social Security would have owed railroaders had their careers been covered by Social Security instead of their own separate law.▸ In fiscal 2024 that transfer alone was $5.29 billion — 36.8% of the system's entire financing, more than a third of every dollar that paid a rail pension, per the Railroad Retirement Board's 2025 Annual Report. Payroll taxes on today's railroaders covered $6.9 billion, or 47.9% — still the largest single source, but not a majority on its own.

On the cost side, 97.5% of the money — $14.3 billion — is a benefit check: retirement, survivor, and disability annuities to railroaders and their families.▸ Running the agency cost $212.6 million, and $164.4 million went to interest expense on the financial-interchange advances the system draws while waiting for Social Security's annual transfer to arrive. Financing sources ($14.40 billion) fell about $298 million short of costs ($14.70 billion) for the year — a gap the 2025 Annual Report says was covered by the National Railroad Retirement Investment Trust's 18.90% portfolio return, not by drawing down reserves the way Social Security's trust funds did in the same fiscal year. Total system assets — the Trust's holdings plus the Treasury-held accounts — stood at $29.6 billion as of September 30, 2024, up $3.1 billion over the year.

Financial interchange money exists because so few people work for a railroad anymore.▸ Average covered employment ran 1.57 million a year in the late 1940s, according to the Railroad Retirement Board's Twenty-Ninth Actuarial Valuation (issued June 2024). Every five-year period since has posted a decline. By fiscal 2024 it was 201,000 — an 87% collapse over roughly 75 years, even after a modest post-pandemic hiring rebound that the Board's actuaries partly credit to Amtrak hiring under the Infrastructure Investment and Jobs Act.

Meanwhile the people drawing benefits didn't shrink nearly as fast.▸ By the end of fiscal 2024 there were 458,000 retirement and survivor beneficiaries on the rolls — more than double the 201,000 people currently paying into the system, per the same Annual Report.

The Board's own actuaries say the system has no projected cash-flow problems for the next 75 years under its automatically adjusting Tier 2 tax rate — but only "barring a sudden, unanticipated, large decrease in railroad employment."▸ That's not a hypothetical sitting on a shelf: Union Pacific and Norfolk Southern have a merger application now under review by the Surface Transportation Board, with the companies targeting a close in early 2027 — the kind of Class I consolidation that has historically meant fewer, not more, railroad jobs.

None of the money story explains what happens when a railroader actually gets hurt and applies for a disability annuity.▸ That's a staffing story, and the Board says so itself, in public, on its own website: "Due to budgetary and staffing constraints, our average processing time for disability applications is 456 days," according to the RRB's Disability Application Determination Average Processing Time page — more than fifteen months for a first decision, not an appeal. Rail labor groups have been warning Congress about the underlying cause for years: field office staff down almost 18% since fiscal year 2015 even as call volume held steady, according to the Transportation Trades Department's policy statement on RRB funding. The RRB's own 2025 Annual Report confirms the Board hit its timeliness targets for every benefit category in fiscal 2024 — "with the exception of disability claims," which it attributes "directly" to "inadequate budget appropriations and loss of experienced staff."

Financing and cost figures cover fiscal year 2024 (Oct. 1, 2023 – Sept. 30, 2024) as reported in the RRB's 2025 Annual Report; employment figures before FY2024 are calendar-year averages from the 29th Actuarial Valuation. The two totals in the money chart are each independently rounded by the Annual Report's own source charts and don't reconcile to the cent.
