Arriva London Engineering Assists In Trial To Turn Older Diesel Engine Powered Buses Green

The title of this post, is the same as that of an article on the Arriva London web site.

This sums up the project.

A new idea to turn older diesel engine buses into much more environmentally friendly vehicles has been developed by Vantage Power Ltd based in Greenford, West London in association with Ensign Ltd, the largest reseller of buses in the UK.

The new unit will start trials in July, when two of Arriva London’s 2005, Volvo B7TL, Euro 3 buses, with Alexander Dennis bodies, VLA99 and VLA100 will resume service following their conversion. The trials are fully supported by TfL.

Effectively two twelve year old buses will become hybrids with new electric drive systems.

The objectives of the project are ambitious.

The new system will be tested to see how well it performs against its targets of 40% reduction in the use of fuel, 80%+ reduction in emissions, and a cost saving for the unit which is estimated to be 80% less than a new Hybrid bus.

They are also developing a technique called geo-fence technology. This is said.

This technology, uses GPS information combined with route information, and can enable the vehicle to ensure its batteries are at full charge before entering certain areas (such as the ULEZ), or past schools, or libraries, and upon entering these areas, the engine can shut itself down and the vehicle then operate as an almost silent ZEV (Zero Emission Vehicle).

So the buses get new hybrid drives, which work as battery buses in sensitive areas and London gets cleaner air. And Arriva London gets a cashback!

I wonder how many old buses can be converted into cleaner hybrids. This conversion was on a Volvo B7TL chassis, of which there were 790 in London alone.

I also wonder if London’s current hybrid buses can have the geo-fence technology applied.

Close to my house there are six London bus routes, that go into or through the ULEX; namely routes 21, 30, 38, 56, 76 and 141 of which the 21, 38 and 76 are New Routemasters, which are modern hybrid buses. In addition, the 141  is run by seven-year-old hybrid buses. These routes would all be candidates for geo-fence technology.
