As part of the Mayor of London’s plan for an increased reliance on energy efficient vehicles to power the city’s transport infrastructure, Transport for London, the British agency responsible for public transportation, has introduced one hybrid bus across route 141. The current hybrid bus is powered by a hybrid diesel-electric engine. Thanks to the mixture of both systems, the bus is able to cover the same distance range as a conventional diesel bus. All the hybrid buses will be marked with a leafy insignia to better communicate to the passengers that they are indeed traveling on an environmentally friendly bus. Here’s hoping that the rest of London, and other cities in the world follow this lead.
“This is a world-first for London marking our commitment to a cleaner, greener public transport network.” said Mayor Ken Livigstone.
