Between May 1997 and February 1998, ACTION took delivery of 25 Dennis Dart SLF “midi” buses, with bodies built by Robert Wright & Son of Ballymena, Northern Ireland. The buses seated 27 people with a single wheelchair space and were the first dedicated low-floor buses in the fleet.
As part of Network 98, Routes 34 and 83 were to be operated by wheelchair-accessible buses, meaning that the Dennis Dart were mostly to be found on these routes, although they were used in other services on the network – including weekends.
With the delivery of full-sized low floor buses commencing in 2004, the Darts’ usefulness gradually declined with some vehicles being withdrawn from service commencing in 2012.
In 2013, three Darts (Buses 140, 141 and 142) were wrapped in a special livery and used to operate the Centenary Loop, a free service which operated around the Parliamentary Zone (although normal Darts also operated this service).
Now, only six Darts are active in the fleet – all of these buses operate the free City Loop service and are based at Belconnen Depot.
