Bus 990 was a Renault PR100.3 with “Starliner” body by Austral Denning, Brisbane.

990 was delivered to ACTION in 1994 as the second of two Renault PR100.3 NGV (Natural Gas Vehicle) – sister unit 991 was delivered first in June 1993.

During its life it has worn three special liveries – the initial Natural Gas livery, the AGL Natural Gas livery (below, left) and its final livery an AOA wrap promoting Aboriginal Reconciliation (below, right).

During 2007, Buses 990 and 991 were withdrawn from service to undergo conversion to run on diesel. This involved the removal of the roof mounted gas cylinders and pods.

Unlike the later CNG buses which have rather obvious roof mounted gas pods, the Renault PR100.3 NGV featured pods sunken into the roof, which meant minimal protrusion on the outside of the vehicle, but a lower interior ceiling at the front of the vehicle. This lower ceiling remained in the buses following their conversions.

Bus 990 was based in Tuggeranong Depot due to its Natural Gas fuelling facilities. But after conversion to diesel in 2007 it was based at Belconnen Depot, until its withdrawal from service in June 2014.
