In Australia, NSW the trains have designated quiet carriages, they’re fully labeled and marked so it’s not easy to miss. I ask people to be quiet all the time. Today a severely mentally handicapped gentleman, who was wheelchair bound and his carer get on to the last carriage of the train which is marked as a quiet carriage, the man was morning and screeching constantly and I asked the carer if he could move him into the next carriage because he was disturbing the silence. I honestly felt like an asshole but it’s a hour long train ride and I could hear him over my headphones.
