Railroad retirement records

From: "Millie Guinup" pices11@twcny.rr.com

Did the railroad keep records of all those that worked on the railroad ... Like Social Security of today?? That would fall under the F.O.I.A. so that we can look up our ancestors .. I would like to find where they last worked, if they collected any benefits after retiring.. who their benefactors [sic] are, children.. ETC.. ...
