(a) A widow(er) of an employee who has completed 10 years of railroad service and had a current connection with the railroad industry at death is eligible for an annuity if he or she:

(1) Has not remarried; and either

(2) Has attained retirement age;

(3) Is at least 50 but less than 60 years of age and became disabled as defined in part 220 of this chapter before the end of the period described in § 216.68 (this results in a reduced annuity);

(4) Is less than retirement age but has in his or her care a child who either is under age 18 (16 with respect to the tier I component) or is disabled and who is entitled to an annuity under subpart H of this part; or

(5) Is at least 60 years of age but has not attained retirement age. (In this case, all components of the annuity are reduced for each month the widow(er) is age 62 or over but under retirement age when the annuity begins. For each month the widow(er) is at least age 60 but under age 62, all components of the annuity are reduced as if the widow(er) were age 62).
