What kind of FCC licensing is req'd for a comms tech(042812) at CSX? I am a soon to retire navy nuclear electrician. open to all info/advice

I worked for the CSX for almost 40 yrs.PO1, what is it you want to know? I was a conducter, however, I had a lot of connections in almost all departments! I can tell you this, every craft has to be tested every 6 months, for the Division that you will be working under the rule changes, that are most people change socks! An most Managers are like Butter Bar LT's small brains in big power places!!!! For the most part, if you keep your nose clean, it it like the ARMY, or Navy!!!! I rather enjoyed my job!
