Unfortunately no booths on the island, sirr is a separate division in the mta, you will have a choice of lower Manhattan or Bayridge Brooklyn as your home station. No rule on hair color, you can have whatever color you choose as far as I know. First day of orientation is hr stuff such as paper work, general rules, and you will receive you epic pass (metro card). Second day is at the union hall, filling out paperwork and getting info on the union. Uniform fittings are usually the second week of training.
