This is now a piece of history.
Unlike their Hispano-bodied cousins which served for a few years
from the start of service 950, the cross border registered Volgren
bodied O405s served for a very short amount of time before service
950 had its fleet switched to the latest MAN NL323F A22 buses on
30th March 2013.
