There was a time when many British towns and cities hummed with the sound of the trolleybus.
Bridging the gap between trams and diesel buses, the benefits of the electric trolleybus include zero emissions on the street, very little noise, and powerful, smooth acceleration. And from the perspective of the operator, trolleybuses offer lower maintenance costs. Given their strengths, it’s a wonder we gave them up in favour of diesel-powered buses. Especially when you consider the damage caused to the environment and our health by diesel emissions.
Different from an electric or hybrid bus that carries its own source of power, a trolleybus draws electricity from two overhead wires using spring-loaded trolley poles (trams require only one wire and pole)
The pollution caused by diesel buses is compounded because the operators are dragging their heels when it comes to buying cleaner vehicles. A quirk of vehicle registration intended to allow one-off vehicles such kit cars to bypass certain regulations has been exploited in order to save money. Using Individual Vehicle Approval (IVA) to register a bus has proved a popular way of bypassing the latest emissions standards.
According to the Society of Motor Manufacturers and Traders, which monitors registrations data, as little as three years ago, more than 80 per cent of buses and coaches bought in Britain failed to meet Euro 6 emissions standards. Euro 6 buses and coaches emit half as much NO2, the harmful gas linked to heart attacks, cancer and asthma.
The centralised power stations used by electric trolleybuses on the other hand, have the potential to be far more environmentally friendly. Electricity derived from renewable sources, considerably adds to the advantages.
Infrastructure costs for electric trolley vehicles equate to 10 per cent of light rail systems and only 20 per cent greater than diesel buses. If one takes into account the ‘environmental advantages, trolleybuses are the cheapest option.
The trolleybus dates back to 1882, and an experimental demonstration in Berlin. It was 1911 before the first trolleybuses arrived in Britain. For much of its existence, the London system was the largest in the world. It had 68 routes, and a fleet of over 1800 trolleybuses. These were eventually all replaced with diesel vehicles. Currently, around 300 trolleybus systems continue to operate in countries around the world.
According to trolleybus.org: “Considerable advances in trolleybus technology, such as much less obtrusive overhead AC traction equipment and solid state sub-stations further enhance an already reliable system. Where tested (Vancouver), passengers prefer to ride on trolleybuses and there is evidence (San Francisco, Seattle) of 10-15% increases in usage where trolleybuses have been installed. When the decision makers understand how enticing and cost-effective state-of-the-art electric trolleybuses can be and how to best implement them, they will be more inclined to push forward with road priority and traffic reduction schemes with these new forms of non-polluting urban transport. We are generating a vision for the planners and politicians to move towards.”
ETA cycle insurance
ETA cycle insurance offers a sympathetic policy on the storage of bicycles. For example, as long as a shed door is locked, the bicycles stored within do not require any further security. In addition, the policy covers stolen quick-release components and for added peace of mind, claims are handled in-house. Furthermore, bikes are never devalued, no matter their age. Hardly surprising that The Good Shopping Guide voted us Britain’s most ethical insurance company 2016.
