I'm just curious as to why buses ordered for Dublin Bus, including their Alexander RL Olympians, ALX400 Volvos, Enviro 400 Volvos and Wright Eclipse Geminis all have customised front end designs. The Olympians have a restructured bumper area that protrudes out more, the ALX400s have a drivers window that's more rounded and not flush with the rest of the body, the Enviros have a front that juts out more and the Geminis have a backwards leaning driver's window. Is there any practical reason for this, or is it just being different for its own sake? I'm not aware of these custom designs being ordered by any other operator! Many thanks.
