Railroad workers earn benefits through the RRB, not Social Security directly. Here's how the two systems compare and connect.
How are the two systems different?
Social Security pays a single benefit based on lifetime covered earnings. Railroad retirement pays a two-part annuity: Tier 1, calculated much like Social Security using combined railroad and non-railroad earnings, plus Tier 2, an additional pension-style benefit based only on railroad service. That Tier 2 layer is why career railroaders typically receive more than they would under Social Security alone. Both systems are funded by payroll taxes, but railroad taxes are higher to support the richer benefit. The RRB administers railroad benefits independently, though it coordinates with Social Security so workers with mixed careers aren't paid twice for the same Tier 1 earnings.
Which one pays more?
For workers with a full railroad career, railroad retirement generally pays more than Social Security because of the Tier 2 benefit. In January 2026, the average regular railroad retirement employee annuity was about $3,636 a month, reflecting both tiers, per the Railroad Retirement Board. Social Security's average retirement benefit is lower because it has no equivalent second tier. However, workers with only a few years of railroad service may see their railroad credits coordinated with Social Security rather than producing a large standalone benefit. Your exact comparison depends on your service months and earnings, available through RRB.gov.
How does each connect to Medicare?
Both railroad retirement and Social Security feed into Medicare, but the enrolling agency differs. For railroad retirees, the RRB often processes Medicare Part A and Part B enrollment and issues the Medicare card, whereas Social Security does so for most other retirees. The Medicare coverage itself is identical, and both groups face the same coverage gaps—deductibles, 20% coinsurance, and no out-of-pocket cap. That's why a Medigap plan matters regardless of which system you retired under. To sort out enrollment timing and Medigap options, call 1-800-MEDIGAP (1-800-633-4427) for free, licensed guidance.
