If you spent your career on the railroad, your retirement runs through the RRB, not just Social Security. This pillar explains how RRB benefits work and how they connect to your Medicare decisions.
What is the Railroad Retirement Board and who does it cover?
The Railroad Retirement Board (RRB) is an independent federal agency that administers retirement, survivor, disability, unemployment, and sickness benefits for the nation's railroad workers and their families. Created under the Railroad Retirement Act, it operates separately from Social Security but coordinates with it. To qualify for a regular railroad retirement annuity you generally need at least 120 months (10 years) of creditable railroad service, or 60 months (5 years) earned after 1995. The RRB covers roughly 1.5 million beneficiaries, including current annuitants, spouses, and survivors. Your railroad service is also why your Medicare card may be issued through the RRB rather than the Social Security Administration.
How do Tier 1 and Tier 2 railroad benefits work?
Railroad Retirement annuities are built on two tiers. Tier 1 is the foundation and is roughly equivalent to what Social Security would pay for the same earnings, using combined railroad and non-railroad credits. Tier 2 is an additional benefit, similar to a private pension, based solely on railroad service and earnings—this is the piece that makes railroad retirement typically richer than Social Security alone. Each tier has its own tax rate, earnings base, and cost-of-living rules. For 2026, the Tier 1 taxable maximum is $184,500 and the Tier 2 maximum is $137,100 (RRB.gov). Understanding which tier drives your check helps you plan taxes and Medicare premiums.
What is the 2026 railroad retirement COLA?
Effective January 2026, the Tier 1 portion increased 2.8%—matching the Consumer Price Index rise used for Social Security—while the Tier 2 portion increased 0.9%, equal to 32.5% of the CPI increase, per the Railroad Retirement Board. As a result, the average regular railroad retirement employee annuity rose about $80 a month to $3,636, and the average combined employee-and-spouse annuity rose about $112 to $5,249. Aged widow(er)s eligible for an increase saw an average rise of $50 to $2,109. Note that some widow(er)s paid under the 2001 law may not receive a COLA in a given year.
How does railroad retirement connect to Medicare?
Most railroad retirees become eligible for Medicare at 65, and because of railroad service the RRB—not Social Security—often handles your Part A and Part B enrollment and issues your Medicare card. Original Medicare leaves gaps: deductibles, the 20% Part B coinsurance, and no out-of-pocket cap. A Medicare Supplement (Medigap) plan can cover those gaps so a hospital stay doesn't drain your annuity. Railroad retirees use the same Medicare and Medigap rules as everyone else, but coordinating enrollment through the RRB has its own quirks.
