(Redirected from Line 4 (Ottawa))
Rapid transit line in Ottawa, Ontario
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 government.
Construction of the line began in 2019. The line was initially considered to be part of the Trillium Line but was given its own number and colour in November 2020. Construction of Airport station was completed in 2023.
The line currently uses the Alstom Coradia LINT 41 diesel light rail trains. Line 4 has 60-metre-long (200 ft) platforms, which are shorter than the 80-metre (260 ft) platforms on the Trillium Line. The difference in length is due to the use of single-car trains instead of two-car vehicles, because of the line's lower projected ridership.
