I am vested in social security, railroad retirement and Cal PERS, having worked different jobs. I would like to start collecting SS next year (turning 62), and then when I turn 66 and 4 months start collecting my maximum benefit from RR retirement. Would SS stop when I start collecting RR retirement? Will collecting SS at 62 reduce my max RR retirement benefit? Do you have any special advice for me or recommendation of who I need to talk with concerning this? THANKS.
