Pros
You will definitely have steady income, health benefits, and job security. Just give up your life. If money is your motivation in life above quality of life---this place is for you.
Cons
You won't see friends or family because your days off may be tuesday and Wednesday. Some jobs work you 6 days a week, and long work days. You make good money but half your paycheck or close to it will be gone in railroad related taxes. Promotions from within are a rare occurrence. You must be in the "click" to get promoted. Nepotism and politics determine hires---not your qualifications. Company culture does not respect your personal time off. They call you on your days off as if you must drop your whole life for them. Vacation time is awful. Overworked but you get one week vacation that first year. Yes. One. So forget about the rail pass you won't have time to use. Some coworkers are rough to put it nicely. job growth is almost impossible (read above). You must know someone important to grow in the company. If not, you get stuck in a job you can't get out of.
