Description of the image
The image shows a large vehicle, viewed from above, sectioned, facing left, used as a public transportation vehicle, called a trolleybus.
The exterior skeleton of the car, also called the car body, is not present here, so the interior is shown from above.
On the floor of the vehicle are placed, on two rows, chairs with backrests, separated by a long and narrow corridor and highlighted by rectangles with an oval, embossed end.
The passenger seats are arranged from right or back, to the left or front, as follows: the last row comprises four seats next to the rear door, then continues with sixteen others, separated by the corridor in two rows with each having eight seats.
Then there is an empty space, next to the central door, reserved for wheelchairs.
Then it continues with four other chairs, positioned faced to face, followed by four more, positioned back to back, located on two rows.
On the left edge is the driver’s cabin, marked by a dotted texture, in which the driver’s seat is placed, highlighted by an embossed square and the steering wheel, next to it, left end, represented by an embossed circle.
The trolleybus is an electric public transport vehicle. This vehicle uses, in most cases, the same chassis (with some modifications) and a body similar to that of a bus; however, the trolleybus is not powered by a thermal engine, but by one or more electric motors. The electric current required for engine operation is provided by two overhead contact lines. The trolleybuses are thus linked to the route of the contact lines. The first trolleybus networks appeared at the beginning of the 20th century. Currently, there are approximately 310 trolleybus networks in 47 states [bibliography 1]. Most are found in Central and Eastern Europe (former socialist states), CIS states (former Soviet Union states), China, North Korea, Italy and Switzerland. The trolleybus dates from April 29, 1882, when Dr. Ernst Werner Siemens put into practice his project called “Elektromote” – in a suburb of Berlin, although more isolated experiments were happening simultaneously in the US [bibliography 2]
The trolleybus has similar transport capabilities as buses,while being less polluting. At the place of operation (in cities) the pollution is zero, but the electric current is often produced in the thermal power plants by polluting processes. If only coal or fuel oil is used for generating electric current, then the pollution as a whole, is similar to a diesel engine bus. The trolley bus is quieter than a bus, which increases the quality of the area through which it passes (but only if, on the same artery, buses do not circulate). On the other hand, a silent vehicle is more difficult to detect by cyclists and pedestrians. Due to the ecological aspects and the quieter engines, it is expected that more citizens will give up their personal car in favor of public transport in case of trolley bus travel, as compared to the bus usage.
There are also cities where the trolleybus has become an object of cultural heritage. In Chile, the trolleybuses in Valparaíso (the only network in this country) have been declared as part of the cultural heritage of the country. [bibliography 3]. Until 1997, there were also floor-mounted trolleybuses, most of them found on the streets of London and, sporadically, on the streets of Hamburg, Moscow or Barcelona. [bibliography 4]
