The Seoul Metropolitan Subway is a metropolitan railway system consisting of 23 rapid transit, light metro, commuter rail and people mover lines located in northwest South Korea. The system serves most of the Seoul Metropolitan Area including the Incheon metropolis and satellite cities in Gyeonggi province. Some regional lines in the network stretch out beyond the Seoul Metropolitan Area to rural areas in northern Chungnam province and western Gangwon Province, that lie over 100 km (62 mi) away from the capital.
Rail transportation in the Philippines is currently used mostly to transport passengers within Metro Manila and provinces of Laguna and Quezon, as well as a commuter service in the Bicol Region. Freight transport services once operated in the country, but these services were halted. However, there are plans to restore old freight services and build new lines. From a peak of 1,100 kilometers (680 mi), the country currently has a railway footprint of 533.14 kilometers (331.28 mi), of which only 129.85 kilometers (80.69 mi) are operational as of 2025, including all the urban rail lines. World War II, natural calamities, underspending, and neglect have all contributed to the decline of the Philippine railway network. In the 2019 Global Competitiveness Report, the Philippines has the lowest efficiency score among other Asian countries in terms of efficiency of train services, receiving a score of 2.4, and ranking 86th out of 101 countries globally. The government is currently expanding the railway network up to 1,900 kilometers (1,200 mi) by 2022 through numerous projects.
Several future projects on the MTR have been put forward by the MTR Corporation to the Hong Kong Government. Some of these are still in planning stage.
SuseoStation is a railroad station on the Suin–Bundang Line and Line 3 of the Seoul Metropolitan Subway. The station is in the Suseo neighborhood of the Gangnam District in Seoul, South Korea. Prior to the Line 3 extension to Ogeum station in 2010, Suseo Station was the southeastern terminus of Line 3. Along with Yangjae station, Suseo Station serves as an important transfer point between Line 3 and buses from/to southern cities such as Seongnam, Yongin, and Suwon.
An infill station is a train station built on an existing passenger rail, rapid transit, or light rail line to address demand in a location between existing stations. Such stations take advantage of existing train service and encourage new riders by providing a more convenient location. Many older transit systems have widely spaced stations and can benefit from infill stations. In some cases, new infill stations are built at sites where a station had once existed many years ago, for example the Cermak–McCormick Place station on the Chicago 'L''s Green Line.
A medium-capacity system (MCS), also known as light rapid transit or light metro, is a rail transport system with a capacity greater than light rail, but less than typical heavy-rail rapid transit. MCS trains are usually 1 to 4 cars. Most medium-capacity rail systems are automated or use light-rail type vehicles.
The history of rapid transit began in London with the opening of the Metropolitan Railway, which is now part of the London Underground, in 1863. By World War I, electric underground railways were being used in Athens, Berlin, Boston, Buenos Aires, Budapest, Glasgow, Hamburg, Istanbul, Liverpool, New York City, Paris, and Philadelphia.
Rapid transit or mass rapid transit (MRT) or heavy rail, 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. 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.
The Manila Metro Rail Transit System (MRTS), commonly known as the MRT, is a rapid transit system that primarily serves Metro Manila, Philippines. Along with the Manila Light Rail Transit System and the Metro Commuter Line of the Philippine National Railways, the system makes up Metro Manila's rail infrastructure.
Gwangju Metro is the rapid transit system of Gwangju, South Korea, operated by the Gwangju Metropolitan Rapid Transit Corporation. The subway network first opened in 2004 with 14 stations. The Gwangju Metro consists of one line, serving 20 operational stations, and operating on 20.1 kilometres (12.5 mi) of route. It crosses both of the major rivers in Gwangju, the Yeongsan River and the Hwangryong River. Most of the system is underground, except for the sections between Sotae-Nokdong and Pyeongdong-Dosan.
The Metro Manila Subway, formerly known as the Mega Manila Subway (MMS) is an under-construction underground rapid transit line in Metro Manila, Philippines. The 33-kilometer (21 mi) line, which will run north–south between Valenzuela, Quezon City, Pasig, Taguig, Parañaque and Pasay, consists of 17 stations between the East Valenzuela and Bicutan stations. It will become the country's second direct airport rail link after the North–South Commuter Railway, with a branch line to Ninoy Aquino International Airport.
Station numbering is a sign system which assigns station codes consisting of a few letters and numbers to train stations. It aims to facilitate navigation for foreign travelers not familiar with the local language by using globally understood characters. The system is now in use by various railway companies around the world such as in mainland China, Indonesia, Japan, South Korea, Singapore, Taiwan, Thailand, and the United States.
New Taipei Metro is a transit system serving New Taipei, Taiwan, operated by New Taipei Metro Corporation. The Danhai light rail, Ankeng light rail, and Circular line are currently in operation, while the Sanying line is under construction. There are many other lines in various planning stages, such as the Shenkeng light rail. Concurrently, these services are connected to Taipei Metro but operate independently.
Rail transportation in the Greater Manila Area is a major part of the transportation system in Metro Manila and its surrounding areas. The railway network, collectively known as the Greater Capital Region Railway System, consists of the Manila Light Rail Transit System (LRT), Manila Metro Rail Transit System (MRT), and Philippine National Railways lines within the region.
