The Manila Light Rail Transit System Line 2, also known as LRT Line 2, LRT-2, or Megatren, is a rapid transit line in Metro Manila in the Philippines, generally running in an east-west direction along the Radial Road 6 and a portion of the Circumferential Road 1.  Although operated by the Light Rail Transit Authority, resulting in its being called "LRT-2", it is actually a heavy rail, rapid transit system owing to its use of electric multiple units instead of the light rail vehicles used in earlier lines and is the only line utilizing such type of system in the country.  Envisioned in the 1970s as part of the Metropolitan Manila Strategic Mass Rail Transit Development Plan, the eleven-station, 13.8 km line was the third rapid transit line to be built in Metro Manila when it started operations in 2003.  It is operated by the Light Rail Transit Authority (LRTA), a government-owned and controlled corporation attached to the Department of Transportation (DOTr) under an official development assistance scheme.

There are three heavy rail and three light rail rapid transit systems operating in Canada.  The Toronto subway was the first rapid transit system in Canada when it opened a 12-station line in 1954.  It has since grown to encompass three heavy rail lines and one intermediate rail line and has the most number of stations of any system in Canada with 69.  Construction has begun on the Eglinton Crosstown Line and the Toronto-York Spadina Subway Extension, which will add 28 new stations and a total of 27.6 km of new track.  Montreal introduced the Montreal Metro in 1966 and has now become the most popular rapid transit system in the country with 1,263,800 daily riders.  The Vancouver SkyTrain, an automated guided line, was opened in January 1986 for the Expo 86 world fair and is the longest rapid transit system in Canada with a system length of 79.6 km .  There are three light rail systems operating in Canada including systems in Calgary (the CTrain), Edmonton (the Edmonton LRT), and Ottawa (the O-train).  There is one light rail system under construction in Kitchener-Waterloo named Ion rapid transit. Copenhagen Metro (Danish: "Københavns Metro" ) is a 24/7 rapid transit system in Copenhagen, Denmark, serving the municipalities of Copenhagen, Frederiksberg, and Tårnby. There are 22 stations in the Copenhagen Metro, a driverless rapid transit system serving Copenhagen, Frederiksberg and Tårnby in Denmark.  Nine of these metro stations are underground, twelve are elevated, and one is street-level.  Christianshavn Station offers transfer between the system's two metro lines (M1 and M2), which share track between Vanløse and Christianshavn stations.  From Christianshavn, M1 branches south traveling to Vestamager Station, while M2 heads southeast to Lufthavnen Station, which serves Copenhagen Airport.  Flintholm, Nørreport and Vanløse stations offer transfer to the S-train, the city's other rapid transit system which the Copenhagen Metro was built to supplement.  Transfer from the Copenhagen Metro to regional trains is possible at Lufthavnen, Nørreport and Ørestad stations.  The City Circle Line, which is under construction and scheduled to open in 2019, is planned to have 17 stations, with transfer between the current and new lines at Frederiksberg and Kongens Nytorv stations.  The new lines will have a stop at Copenhagen Central Station (København H), the largest train station in Denmark.
