One of London’s biggest bus operators, Go-Ahead, has taken delivery of 39 new ultra-low emissions buses built as partnership with Alexander Dennis Ltd (ADL) and BAE Systems. How far is London ahead of Dublin in alternatively fuelled public bus transport. Indeed most UK cities are so far ahead, it should be questioned.
The first 39 Enviro400H double-deck buses with Series-E hybrid technology were delivered to Go-Ahead London last week.
The new model uses ultra-capacitor energy storage to reduce lifecycle costs and has achieved Ultra Low Emission Bus certification with 37 per cent lower emissions than conventional diesel buses.
Richard Harrington, Go-Ahead London Engineering Director, said, “With 245 [of them] already in our fleet, we know ADL and BAE Systems’ Enviro400H helps us improve London’s air quality. This experience gave us the confidence to place a volume order for the new Series-E version and we look forward to recognising its improved fuel economy and lower cost of ownership.”
The Series-E maintains the hybrid system in which the diesel engine acts only as a generator to produce energy for the electric drivetrain. This now uses a lighter and more compact motor, which no longer requires a speed reducing gearbox, increasing efficiency and minimising wear.
Due to this, and other improvements, it has been predicted that over 10 years, costs will be reduced by 53 per cent.
Passengers will enjoy smooth acceleration and braking, while pedestrians and local residents can benefit from the arrive-and-go mode which turns off the engine at low speed and at bus stops; reducing noise pollution and emissions.
The first 39 buses have gone into service on Transport for London route 36 between Queen’s Park and New Cross Gate. Another 26 are on order for routes 77 and 87.
Matthew Lawrence, BAE Systems Business Development Manager, said, “With Ultra Low Emission Bus certification, the Enviro400H with Series-E technology and ultra-capacitor energy storage not only suits London operators, but gives bus companies around the country the opportunity to apply for Department for Transport funding with a proven solution supported by existing infrastructure.”
