Monorail in the context of "Vehicle"

Rapid transit, mass rapid transit (MRT) or rail rapid transit (RRT) and commonly referred to as metro, is a type of high-capacity public transport that is generally built in urban areas. A grade separated rapid transit line below ground surface through a tunnel can be regionally called a subway, tube, metro or underground. They are sometimes grade-separated on elevated railways, in which case some are referred to as el trains – short for "elevated" – or skytrains. A common alternative term for rapid transit in North America is heavy rail. Rapid transit systems are usually electric railways that, unlike buses or trams, operate on an exclusive right-of-way, which cannot be accessed by pedestrians or other vehicles.

Modern services on rapid transit systems are provided on designated lines between stations typically using electric multiple units on railway tracks. Some systems use guided rubber tires, magnetic levitation (maglev), or monorail. The stations typically have high platforms, without steps inside the trains, requiring custom-made trains in order to minimize gaps between train and platform. They are typically integrated with other public transport and often operated by the same public transport authorities. Some rapid transit systems have at-grade intersections between a rapid transit line and a road or between two rapid transit lines.

An electric vehicle (EV) is any motorized vehicle whose propulsion is provided fully or mostly by electric power, via grid electricity or from onboard rechargeable batteries. EVs encompass a wide range of transportation modes, including road (electric cars, buses, trucks and personal transporters) and rail vehicles (electric trains, trams and monorails), electric boats and submersibles, electric aircraft (both fixed-wing and multirotors) and electric spacecraft.

Early electric vehicles first came into existence in the late 19th century, when the Second Industrial Revolution brought forth electrification and mass utilization of DC and AC electric motors. Using electricity was among the preferred methods for early motor vehicle propulsion as it provided a level of quietness, comfort and ease of operation that could not be achieved by the gasoline engine cars of the time, but range anxiety due to the limited energy storage offered by contemporary battery technologies hindered any mass adoption of electric vehicles as private transportation throughout the 20th century. Internal combustion engines (both gasoline and diesel engines) were the dominant propulsion mechanisms for cars and trucks for about 100 years, but electricity-powered locomotion remained commonplace in other vehicle types, such as overhead line-powered mass transit vehicles like electric multiple units, streetcars, monorails and trolley buses, as well as various small, low-speed, short-range battery-powered personal vehicles such as mobility scooters.

An elevated railway or elevated train (also known as an el train or el for short) is a railway with the tracks above street level on a viaduct or other elevated structure (usually constructed from steel, cast iron, concrete, or bricks). The railway may be a broad-gauge, standard-gauge or narrow-gauge railway, rapid transit, light rail, monorail, or a suspension railway. Elevated railways are normally found in urban areas that would otherwise require impracticably many level crossings. Usually, the tracks of elevated railways that run on steel viaducts can be seen from street level.

Barmen is a former industrial metropolis of the region of Bergisches Land, Germany, which merged with four other towns in 1929 to form the city of Wuppertal.

Barmen, together with the neighbouring town of Elberfeld founded the first electric suspended monorail tramway system, the Schwebebahn floating tram.

Rapid transit, mass rapid transit (MRT) or rail rapid transit (RRT) and commonly referred to as metro, is a type of high-capacity public transport that is generally built in urban areas. A grade separated rapid transit line below ground surface through a tunnel can be regionally called a subway, tube, metro or underground. They are sometimes grade-separated on elevated railways, in which case some are referred to as elevated, el or L trains – short for "elevated" – or skytrains. A common alternative term for rapid transit in North America is heavy rail.

The Ueno Zoo (恩賜上野動物園, Onshi Ueno Dōbutsuen) is a 14.3-hectare (35-acre) zoo, managed by the Tokyo Metropolitan Government, and located in Taitō, Tokyo, Japan. It is Japan's oldest zoo, opened on March 20, 1882. It is served by Ueno Station, Keisei Ueno Station and Nezu Station, with convenient access from several public transportation networks (JR East, Tokyo Metro and Keisei Electric Railway). The Ueno Zoo Monorail, the first monorail in the country, connected the eastern and western parts of the grounds, however the line was suspended from 2019 onwards due to ageing infrastructure until being announced as closing permanently on 27 December 2023.

The zoo is in Ueno Park, a large urban park that is home to museums, a small amusement park, and other attractions. The zoo is closed on Mondays (Tuesday if Monday is a holiday).

The Chongqing Rail Transit (branded as CRT; also known as Chongqing Metro) is the rapid transit system in the city of Chongqing, China. In operation since 2005, it serves the transportation needs of the city's main business and entertainment areas in downtown as well as the inner suburbs. As of December 2023, CRT consists of twelve lines with a total track length of 561.18 km (349 mi). Lines 1, 4, 5, 6, 9, 10, 18, the Loop line, Jiangtiao line, and Bitong line are conventional heavy-rail metro lines, while Lines 2 and 3 are high-capacity monorails. To keep up with urban growth, construction on several other lines is under way.

The Chongqing Rail Transit is a unique transit system owing to the nature of Chongqing being a densely populated yet mountainous city with multiple river valleys. Two lines use heavy-monorail technology, leveraging the ability to negotiate steep grades and tight curves and rapid transit capacity. They are capable of transporting 32,000 passengers per hour per direction. However the busiest section of Line 3 reaches a peak passenger volume of 37,700 pphpd in 2019. At 98 km (61 mi), the system's two monorail lines form the longest monorail system in the world, with Line 3 being the world's longest single monorail line. The length and the capacity of its monorail network both also make it the world's busiest monorail system, with a total of 94 million and 250 million rides in 2015 on Line 2 and Line 3, respectively. Line 3 is therefore the world's busiest single monorail line.
