In Germany the field trips like this are typical even for kids under 5, though the control types vary. Sometimes it's one teacher, sometimes one in front and one in back. Sometimes they just make the kids pair up and hold hands, and sometimes they give them a rope that they have to hold onto. This facilitates school age kids in all grades who are capable of riding city buses and trains on their own to and from school. Obviously the lack of child abduction in the news plays a role in parents allowing this.
