What passes for logic in industrial design at Queensland Rail. The last generation of trains had two big green "open doors" buttons at either side of the doors.
The new generation trains instead have the "emergency open" and "emergency intercom" buttons in THOSE EXACT SAME LOCATIONS. Both of these bear "large fine for misuse" warnings.
The actual open-door button is in the middle of the doors. The PA reminds passengers of the location of the exit button at every stop, because bad design is forever.
