"Rapid transit or mass rapid transit (MRT), also known as heavy rail or metro, is a type of high-capacity public transport that is generally built in urban areas."
An underground train system operating on electrified rails, typically used for public transportation in cities.
Subway System Overview: Understanding the structure of a subway system, including stations, lines, and routes.
Subway Map Reading: Being able to read and interpret a subway map, including understanding symbols, colors, and routes.
Ticketing and Payment: Knowing how to purchase, use, and refill subway tickets or passes, including understanding fare structures and discounts.
Navigating Stations: Being familiar with station layouts and how to enter, exit, and transfer between stations and lines.
Subway Safety: Understanding safety rules and regulations, including how to use emergency equipment and respond to emergencies.
Subway Etiquette: Knowing proper behavior and practices while riding the subway, including respecting other passengers, using headphones, and not blocking pathways.
Subway Accessibility: Understanding the accessibility features available for passengers with disabilities, including ramps, elevators, and audio announcements.
Subway Maintenance and Upgrades: Understanding how the subway system is maintained and upgraded, including construction projects and system improvements.
Subway History: Learning about the history of subway systems around the world, including their origins and evolution.
Subway Technology: Understanding the technology and infrastructure that make subways operate, including signaling, communications, and power systems.
Subway Train: An electric train that runs on a track underground or above ground.
Metro Subway: A train that is used for urban transportation, mostly underground, that has multiple stops along a fixed route.
Light Rail: A type of electric train that usually runs on the surface, with fewer stops and better speed than other systems.
Monorail: A train that runs on a single, elevated rail, that is sometimes used as an attraction or for short transportation distances.
Aerial Tramway: A suspended cable system that transports people from one platform to another.
Funicular: A cable-driven train system that moves up and down a steep hill or incline.
Bus Rapid Transit (BRT): A public transportation system that uses dedicated bus lanes, stations, and technology to improve transit times.
Tram or Streetcar: A type of electric train that mostly runs at-grade or on tracks along city streets.
Maglev Transport: A high-speed train that uses magnetic levitation to glide above its tracks.
Hyperloop: A pneumatic tube train system that uses vacuum technology to propel passengers at high speeds.
Bullet trains/Shinkansen: A high-speed train that connects different regions of a country.
Intercity trains: Trains that operate between cities or towns.
Commuter Trains: Trains that are designed to accommodate the daily travel needs of commuters by passing through or connecting big cities with satellite towns.
Express Trains: Trains that make limited stops to reach destinations faster.
Regional trains: Trains that cater to regional travel requirements connecting various regions in a country.
Long-Distance Railway Trains: Trains that cover long distances within or outside the country.
Freight trains: Trains that carry cargo from one place to another.
Rapid Transit or Mass Transit: A form of public transit that includes systems such as subways, metros, and buses that provide transportation to large, urban areas.
"A rapid transit system that primarily or traditionally runs below the surface may be called a subway, tube, or underground."
"Unlike buses or trams, rapid transit systems are railways, usually electric, that 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."
"The world's first rapid transit system was the partially underground Metropolitan Railway which opened in 1863 using steam locomotives, and now forms part of the London Underground."
"In 1868, New York opened the elevated West Side and Yonkers Patent Railway, initially a cable-hauled line using static steam engines."
"As of 2021, China has the largest number of rapid transit systems in the world—40 in number, running on over 4,500 km (2,800 mi) of track."
"The world's longest single-operator rapid transit system by route length is the Shanghai Metro."
"The world's largest single rapid transit service provider by number of stations (472 stations in total) is the New York City Subway."
"The three busiest rapid transit systems in the world by annual ridership are the Shanghai Metro, Tokyo subway system, and the Moscow Metro."
