I'm guessing your asking about a conductors pay. It's a wide range from $0 on up. There isn't a bi-weekly set figure except possibly a yard job working 5 days a week without overtime. The figures you posted are most likely for road service. Everything is based on seniority and business. Extra boards protect and fill in for vacancies on jobs when a regular assigned person is on vacation, has a doctor appointment, sick ect....unless there is some form of gaurentee pay for the extra boards which not sure if UP has them it's a system of "feast or famine". A person could work a lot or sit around for days waiting to work. I'm sure someone from the UP can answer that question. Remember being low man in seniority doesn't get the preferred jobs. It could take years to hold down a decent job. During my railroad career I never cared about what someone else made only one that counted was me. I've witnessed mindless envy when others were jealous of anothers earnings. The railroad is all about the individual how aggressive one wants to be. This applies to all railroads.
