From Track worker you could go into RTO and be a train operator.
Personally I'm no fan of RTO. It is a very, very strict department with little leeway compared to Track (Maintenance Of Way, MOW).
You can also go to 3rd Rail aka Power Distribution (Gray helmets) where I am. You won't work as hard in Track but senority moves very, very, slow increasing your odds of being nights longer.
Also in my department they're a fewer specialist jobs. Just a chauffeur, welders, and asbestos gangs which go to school and become asbestos certified handlers by the state.
For the younger guys track is a good dept if your a hustler on the outside. Me and some other guys who started when we were in our early twenties quickly picked a specialist job when we could operating a bobcat, payloader, Hi-Lo machine, etc. Some stayed nights working second jobs (with the TA's permission of course) or days working a second front at night with that training. It's something you can use on the outside.
Some guys even got their CDLs and stayed nights and drove school buses in the daytime.
Also supervision moves higher quicker in track Department.
In my opinion track has a lot more benefits if you don't mind working.
