RAILROAD RETIREMENT BOARD : NO SOCIAL SECURITY NUMBER?

If you're looking for a Social Security number, on the Death Index, or because you want to send for the Original Application, which would give you the mother's maiden name for an ancestor, and can't find one, the reason may be that the person never applied or paid into the system because they were WORKIN ON THE RAILROAD! Here is a link to the RAILROAD RETIREMENT BOARD. It announces that the information will now be acquired through the National Archives.
