That aside, are there any automated railways anywhere that don't have
platform edge doors?

The above-ground stations on the Copenhagen metro don't have platform
edge doors. See, for instance,

The Copenhagen metro trains run without any staff on board (although
there are roving staff who do ticket inspections etc).
