This vehicle is one of only two Volvo B10M ‘mk2’ chassis fitted with bodies constructed by short-lived company Queensland Bus Builders (QBB) – who took over production of a contract with the Council from Commonwealth Engineering. The remaining vehicles bodied by QBB were on improved Volvo B10M ‘mk3’ chassis. Bus 185 was originally delivered new to the Carina bus depot in the eastern suburbs during May 1989.
It spent almost two-decades as a faithful Carina vehicle until transfers in it last years of service saw it venture between depots on the Brisbane’s north and south sides, before returning to Carina where it remained in service until May 2010. This vehicle was part of a batch of Council buses destined for service in Papua New Guinea but this never eventuated. Accordingly, the vehicle was retained by Council at their Larapinta depot until it was donated for preservation in February 2012.
