I had an opportunity to work for CSX, but after checking them out decided that there was no way I'd ever work there. Horrible safety record and deferred maintenance, and it seemed to be a conscious choice from up top. Only got worse while John Snow ran the company, can't believe Bush appointed him to anything.
In contrast NS was just the opposite when it came to their track, and even improved our track at Conrail, which was already pretty darn good on the mains I worked (though in labor relations and operations we were expecting revenge for Sherman's to march to the sea when the NS boys came up to take over!)
Great! </sarcasm> Their Atlanta-Chattanooga main line runs right behind our house!
