The Railroad Retirement Board administers comprehensive retirement-survivor and unemployment-sickness benefit programs for the Nation's railroad workers and their families. The Railroad Retirement Board was originally established by the Railroad Retirement Act of 1934, as amended (45 U. S. C. 201--228z-1). The Board derives statutory authority from the Railroad Retirement Act of 1974 (45 U. S. C. 231-231u) and the Railroad Unemployment Insurance Act (45 U. S. C. 351-369). It administers these acts and participates in the administration of the Social Security Act and the Health Insurance for the Aged Act insofar as they affect railroad retirement beneficiaries.
