Few objects are more emblematic of London than the double-decker bus. No London tourist brochure would be complete without a picture of one these beauties. And it would be rare to find a cinematic montage of the city without a shot of a bright red double-decker bus zooming through the streets. The symbolic nature of the double-decker bus makes it all the more exciting that London's transport network last year introduced a new line of eco-friendly double-decker buses.
In March 2015, Transport for London (TfL) announced that it would add five all-electric, zero-emission double-decker buses to its transport system. The buses use lithium iron phosphate batteries, which enable them to travel for more than 24 hours and approximately 300 kilometres without stopping to recharge. Each bus includes air conditioning and can hold 81 passengers (54 seated, 27 standing). The buses and their batteries were designed by BYD, the world's largest electric vehicle manufacturer. BYD will also help install the London bus charging stations and help train drivers.
