No. 440 is a 2017 Alexander-Dennis Enviro 400 integral with H45/27F.
It wears the Blackpool Transport ‘Palladium’ livery (grey and light-yellow) rather than the traditional green and cream.
The Enviro400 was designed by ADL as a Low Emission Bus and is available with variety of powertrains including fully electric and hybrid electric.
No. 440 is one of a large batch of ADL Enviro 400’s delivered to Blackpool Transport between 2016 and 2020.
Here on Street View in May 2018 No. 440 is seen on the Fishergate Hill in Preston (it is not in service).
