Management Experienced First line Supervisor/Transportation?

Can anyone explain what this job would REALLY be like. I've read it on the BNSF web-site, I would like to get some of your thoughts about this job. I realize that only "outsiders" are considered for this particular job. How would an outsider with no prior RR experience be treated being a supervisor right off the bat?

Thanks to all in advance.
