Industrial or Snowy Industrial!
Egypt wouldn't make any sense with 3 trains, abandon coalmine would be pretty cool but map seems to have too many things that abandon places don't have (3 active trains, electrified water)
Alpine is overused and looking at fact you are pretty new to TF2 mapping, i have to say it would be really hard for you to make alpine entry that would stand out of the mass.
Snowy industrial would be best out of two industrial you have in vote, there is not many maps themed like that (Expect few artpass maps) and it would stand out of the mass.
