Bus 703 was a Renault/MACK PR180.2 articulated bus with Ansair Tullamarine body.
It the first Renault PR180.2 in service and the first to be withdrawn from service: it entered service on 15 April 1988 operating Route 435 from Belconnen to Barton; in 2009 it was an insurance write-off following a driveline failure incident in 2006. The incident resulted in major mechanical and structural damage being caused to supporting chassis structural members, associated pneumatic and electrical conduit runs as well as driveshaft and transmission components.
After an engine fire damaged the trailer section of Bus 724, the trailer of Bus 703 was removed and attached to the front of Bus 724 – the end result being that the front section of 703 and the trailer section of 724 were scrapped for parts, while the front section of 724 and trailer section of 703 re-entered service as Bus 724.
In early 2009 the front section of 703 was assigned to Belconnen Fire Station for use in training exercises.
