Hi...In answer to those who responded to my posting about locating information on railroad workers I'm posting the following locations. I'll answer individual questions separately. I'm not certain about the extent or if there is information on casual workers. My ancestor applied for retirement benefits even though his work history was sparodic and I received a monthly summary of his employment from about 1906 through 1958, information about his three marriages, and some non rr related work history. I was able to track him across the US and even have a possible "alias" to check out. Hope this helps some of you. connie Web site for the Railroad Retirement Board....check out regional office addresses to find one closest to your ancestor's location and then write a snail mail and they will check for his employee records. http://www.rrb.gov/ This is the address I used to request a search...It can take from 30-60 days to complete and the search fee is not refundable, even if they are unable to locate the information requested or the file has been destroyed. I think the fee was $15 or maybe a bit more. By the way, the social security number of my ancestor was not the one that shows the holder to be a railroad employee, so even though he was not "career" they did have extensive records for him.
