Mayor of London Bus for London
In 2008 Boris Johnson announced the replacement of the old Routemaster bus. A competition was held for the design of a new bus; this was to be called a New Bus for London. A set of specifications were announced for the new bus; these stated the bus was to be two-man operated, have access for the disabled and a jump-on-and-off platform at the rear. For those of you that have seen the original specification and have also seen the bus that is now the so-called New Bus for London, or the New Routemaster as it is officially known, you will notice that the specification does not match the new bus. So for this reason we ask you, when viewing this proposed bus scheme, to consider this in mind.
A member of this club entered the competition with a bus like no other seen before. The strange wheel arrangement is to support a segmented pantograph at the top of the bus that picks up its supply from overhead power lines. These power supply lines do not have to be over the entire length of the journey, as the pantograph is able to detect the presence of the power lines and raise itself to engage the power to charge the onboard batteries that power the bus. This means that, at junctions, you do not have the complexity of overhead wires that you use to have with trolleybuses and trams. The pantograph detects the oncoming junction and lowers itself allowing the bus to run on batteries.
As you would expect with any electric
vehicle, it has regenerative braking, which is achieved by charging a
series of high-capacity capacitors. This saves battery life and is also
more efficient. The batteries and the capacitors are inserted into the
bus, through the side between the wheels, and are all connected to a
common power supply system. So depending on the route chosen for the
bus, and the availability of overhead power, these interchangeable power
pods can be reconfigured for the best use of the route chosen. As these
power pods are inserted into the side of the bus they can quickly be
changed to either reconfigure the bus or change a defective power pod.
In the event that the bus has to travel a long distance without overhead
power there is a diesel generator under the staircase. To achieve the
weight distribution for the batteries and the bus, the bus has a side
chassis and a central structural member under the floor.
