45 U.S.C. § 231o — Private pensions

This section is one undivided provision, with no lettered subsections. Nothing in this subchapter stops or discourages an employer from paying a retired employee a pension or gratuity in addition to the annuity that employee already gets under this subchapter. Nothing in this subchapter ends any pension or gratuity trust that an employer had already created before this law existed. A person's annuity under this subchapter cannot be reduced because an employer also pays that person a pension or gratuity — with one exception: this protection does not cover the "supplemental annuity" described in section 231a(b), so a supplemental annuity can still be affected by an employer pension.
