Bus 506 is a Scania K360UA 6×2/2, the first new articulated bus delivered to ACTION since Bus 989 in June 1993. It was delivered on 13 July 2012 and entered service at Belconnen Depot on 3 September 2012.
The bus was the first at ACTION to feature a Custom CB80 body and was the first wheelchair-accessible articulated bus in the fleet.
Sneak peeks of the bus, which ACTION named “Big Bendy”, were posted on twitter in the month leading up to delivery, with several shots showing the bus having its body fitted. It was launched to the media on 1 August 2012 by Chief Minister Katy Gallagher.
506 was the first delivery of an order of 20 Scania K360UA articulated buses. This order was extended by 13 buses which fully replaced the Renault PR180.2 articulated buses, with the last bus (538) delivered in October 2013.
