Yeah, this bus is clearly intended to be a school bus but it’s missing too much detail. If the absence of the door is a valid clue, then so is the absence of the big red stop sign that is on the non-door-side.
The other day someone pointed at the open platform of RM1353 and asked me: did you take the doors off this bus? “No, it was built that way.” She looked amazed, and pleased.
