My ex husband a retired railroad employee passed recently. I have been getting a portion of the pension since 62 when he retired
I got a letter from railroad retirement to call them. I'm I losing the amount I have been receiving

Hi. My expertise is limited to Social Security benefits, not Railroad Retirement (RR) benefits. I do have a limited knowledge of RR benefits, but there's not enough information in your question for me to be able to offer any advice. It sounds like you'll need to contact the Railroad Retirement Board (RRB) for an explanation.

Best, Jerry
