Subways the world over do without just fine.

  Subways in my country at least definitely do have guards (but they also have human drivers, so I don't think the two are really related).

  Every train in London, even the fully automated ones, have at least one person onboard. Maybe at some point that will change, but there's a lot of pressure against it.

  The train system in Sydney, Australia has a guard cabin which it's recommended to ride near at night when there aren't many people about.

    I don't know if it's because I've only been here four years, or because I'm from a city/country with a lot more crime, or it's my train line, but I've never felt unsafe on the late trains or the night buses. Also, for the unfamiliar, 'guard' here does not mean an armed guard.
