The image shows a trolleybus station, seen from above.
At the top is the actual station, located on the sidewalk, in the center, framed by two billboards or two windows, left and right, rendered by a vertical rectangle, thin, filled with texture of parallel and oblique lines.
Above, between the two panels, are five square seats for the passengers waiting for the trolleybus, being represented by five blank squares.
To the left of the row of chairs is a trash can, highlighted by a circle filled with dotted texture.
The sidewalk platform, on which the station is located, is represented embossed.
The sidewalk is separated from the street, which is located in the lower half of the image, by the curb, a higher edge, built of concrete blocks lined up along the road.
The border or the curb is located in the middle of the image, rendered by a rectangular, narrow and horizontal strip, consisting of two parallel lines, joined by short, vertical and parallel lines.
Below the curb is the route specially arranged for the trolleybus power lines, respectively the installation of overhead cables, represented by two horizontal and parallel, thicker lines.
Below the trolleybus overhead cables is the road marking for other cars, which can travel on the street, always giving priority to trolleybus or tram routes.
The simple dashed road marking is highlighted by a dashed, horizontal line.
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]
