I'll chime in first.
The job of conductor, like any other job, has its moments. Since you are coming from a RR family, you already know about the pros and cons of RR life. Make no mistake, this is a lifestyle change, not just a change in jobs.
I came to the RR from the legal profession. Prior to entering the law, I worked in aircraft machine shops and truely enjoyed working for a living. After four years in the law, I found that I could hardly drag myself out of bed to face the legal system. Therefore, when the opportunity to go to work for the BNSF as a conductor trainee presented itself, I jumped at it. I find I actually enjoy working at an honest job for a living, rather then preying off of people's misfortunes in life.
I think if you are coming from law enforcement you will enjoy the RR. The work is governed by a lot of rules and regulations, it is outside for the most part, YOU WILL meet every type of person there is (although unlike being a cop, you won't meet them at their worse); and it is semi-physical. Some days you'll cuss the company and wonder what in the world you got yourself into and others you'll sit back and be amazed that they pay you to do what you are doing. In other words, it is just like every other job in the world. If you really like law enforcement, there are special agent jobs with the BSNF as well. These are the old railroad police.
I would have one word of caution, have your bother's buddy tell you about the current hiring spree BNSF is on. You can see my other postings for more information. I love the job and had no illusions about what was involved in RR work. I live in a big RR town in Kansas and have many friends that still work for the BNSF. However, I am 3 weeks from completing the conductors trainee course and have no idea where I will be going to work. Other trainees in different cities tell me the same thing. All the boards locally are full and in looking out of state, the locations with openings all have classes that will mark up in the next week or so. So it appears that after they have paid me to learn the job, there may not be a job available. The BNSF is a good company to work for, but their curent hiring practices leave much to be desired. They are hiring in anticipation of mass retirements in 3-5 years. So if you can make it that long, there will be many opportunities and job security.
In short, ask around. This bulletin board is a great sourse of information. I found the people here are more than willing to give you objective information that is accurate. This is because they have no agenda. If you look around, you'll find a posting on almost every subject you can think of from the hiring process through training to actual employment. The people here are experienced and more than willing to impart the wisdom of that experience. All you have to do is ask.
Good luck in whatever your decision is.
