Easier to get on than youd think, buddy o mine was an engineer for csx, they canned him for speeding after the 3rd incident. Which is bs, because he was a conductor, and never wanted to be an engineer. They force all conductors to become engineers now, as they are trying to cut jobs with ptc. Rr jobs are good, but the same problem as trucking exist, union busting with subcontractors, elimination of job classifications due to flexibility, eroding pay and bennies, etc. I turned down being a signal maintainer for Ns a few months ago, btw.
