I work for NS,as a conductor.Don't know about CSX,but NS expects you to work by the rules,do so and you will not have a problem.the way I look at it ,when NS offered me the job and I accepted,I agreed to work by the rules.Once you are out here, there are people who will try and influence you ,both good and bad about the company or the way to do a particular task.My advice would be to make your own decisions based on safety and tapping an oldhead's experience,but don't let anyone pressure you to do any thing you think may be unsafe.I enjoy my job and would not want to be disiplined for getting caught taking a short-cut to save a minute or two,it just is not worth it.This job is not anywhere close to splitting the atom but the equipment can bite you if you try to bend the rules to get a quit,I want to go home to my family in one piece.Best of luck,work safe.
