DA class

The DA class consists of 157 Dennis Trident 2 double-decker buses with Alexander ALX400 bodywork, numbered DA1–DA6, DA12–DA22, DA84–DA101 and DA105–DA226.

DA1–DA6, DA12–DA22, DA84–DA101 and DA105–DA165 were produced by Dennis/Alexander, while DA166–DA226 were produced by TransBus.

DA class vehicles are currently operated by Localbus East Anglia at Ipswich; Localbus Scotland at Inchinnan; and Localbus West Midlands at Birmingham and Yardley Wood. Additionally, DA class vehicles currently serve as driver training vehicles with Localbus East Midlands at Chesterfield and Nottingham and Localbus Scotland at Barrhead and Inchinnan.

Former class members DA7–DA11 and DA23–DA32 were withdrawn and sold in December 2015 as a result of their age and non-DDA status, followed by DA33–DA83 and DA102–DA104 in August 2017.
