Line 4 (O-Train)
Line 4 (), also known as the Airport Link (), is a diesel light rail line on the O-Train network in Ottawa, Ontario. The line provides a connection between Line 2 (also known as the Trillium Line) at South Keys station to Ottawa Macdonald–Cartier International Airport. The line opened on January 6, 2025. History Initial plans for expansions of the Trillium Line in 2013 considered an expansion to Ottawa Macdonald–Cartier International Airport. However, these plans were discarded due to lack of funding and a focus on attracting ridership from the south of Ottawa. In 2016, the Ontario provincial government committed $1 billion to O-Train expansion, providing half the required funding for an extension to the airport, with an additional station at the EY Centre. Additional funding was acquired for the Airport Link through federal funding and the airport authority, who constructed the airport station for approximately $20 million, with $6.4 million from the federal governmen ...

The O-Train is a light rail system in Ottawa, Ontario, Canada, operated by OC Transpo. The O-Train system consists of three lines, all of which are fully Grade separation, grade-separated. As of March 2025, one line is currently being extended and a new line will be added as part of the Stage 2 project, with new segments being phased in between 2025 and 2027. The O-Train network currently operates one Electric multiple unit, electric light rail line, Line 1 (O-Train), Line 1, and two Hybrid rail, diesel light rail lines, Line 2 (O-Train), Line 2 and Line 4 (O-Train), Line 4. Line 1 travels in a 2.8 km tunnel in the downtown core, and the rest of the network continues to operate grade-separated on surface-level, trenched, or elevated tracks. Line 1 is being extended in both directions, with the eastward extension to Trim station in Orleans scheduled to open first in 2025. By 2027, the westward expansion of Line 1 to Baseline station, Algonquin station and the construction of new L ...

Hybrid Rail
Hybrid rail, also known as diesel light rail transit (DLRT), is a mode of Passenger train, passenger rail service unique to North America that uses lightweight Multiple unit, multiple unit trains—typically Diesel multiple unit, diesel multiple units (DMUs)—operating on the Freight railroads in the United States, national rail system. In the United States, these vehicles do not comply with Federal Railroad Administration (FRA) Crashworthiness, Tier I crashworthiness standards and must operate under shared-use waivers that require temporal separation from Rail freight transport, freight rail traffic. Hybrid rail differs from Commuter rail, conventional commuter rail by offering frequent, all-day service rather than being limited to peak-period operations. However, service frequencies are generally lower than those of urban light rail systems. Although often categorized as a subset of light rail, hybrid rail systems employ mainline railway infrastructure and are closer in function ...

Airport Rail Links In Canada
An airport is an aerodrome with extended facilities, mostly for commercial air transport. They usually consist of a landing area, which comprises an aerially accessible open space including at least one operationally active surface such as a runway for a plane to take off and to land or a helipad, and often includes adjacent utility buildings such as control towers, hangars and terminals, to maintain and monitor aircraft. Larger airports may have airport aprons, taxiway bridges, air traffic control centres, passenger facilities such as restaurants and lounges, and emergency services. In some countries, the US in particular, airports also typically have one or more fixed-base operators, serving general aviation. Airport operations are extremely complex, with a complicated system of aircraft support services, passenger services, and aircraft control services contained within the operation. Thus airports can be major employers, as well as important hubs for tourism and o ...

Railway Lines Opened In 2025
Rail transport (also known as train transport) is a means of transport using wheeled vehicles running in tracks, which usually consist of two parallel steel rails. Rail transport is one of the two primary means of land transport, next to road transport. It is used for about 8% of passenger and freight transport globally, thanks to its energy efficiency and potentially high speed.Rolling stock on rails generally encounters lower frictional resistance than rubber-tyred road vehicles, allowing rail cars to be coupled into longer trains. Power is usually provided by diesel or electric locomotives. While railway transport is capital-intensive and less flexible than road transport, it can carry heavy loads of passengers and cargo with greater energy efficiency and safety. Precursors of railways driven by human or animal power have existed since antiquity, but modern rail transport began with the invention of the steam locomotive in the United Kingdom at the beginning of the 19th ...
