Ottawa Unveils O-Train Line 4 to Transform Airport Travel
01.03.2025
Ottawa’s O-Train Line 4 Boosts South-End Travel to Airport. This was reported by the railway transport news portal Railway Supply.

Ottawa joyfully opened the O-Train Line 4 extension to the airport in January. This vibrant upgrade greatly improves travel for south-end residents and eager visitors alike.
Ottawa Welcomes Line 4 Service
Construction teams tirelessly expanded Line 2, dubbed the Trillium Line, over several years. Meanwhile, they boldly launched Line 4, connecting South Keys to the city’s international airport.

Service proudly began on January 6, thrilling commuters with a fast airport route. Trains now whisk passengers between South Keys, Uplands, and the busy airport every day.
Line 4 fully operates in Ward 10, also known as Gloucester-Southgate, with sleek trains. These modern marvels easily carry up to 600 people, offering seats and standing room.
Locals and travelers now speed from the airport to downtown in under an hour. To do this, riders hop on Line 4 and switch to Line 2 at South Keys.
At Bayview, Line 1, called the Confederation Line, ties south-end commuters to downtown. This vital link sharply accelerates public transit access across the urban core.
OC Transpo smartly retained the 97 bus running from the airport to Hurdman Station. This choice guarantees a smooth shift until Line 4 runs seven days weekly.
Likewise, bus 2 keeps connecting Bayview to South Keys alongside the O-Train. Thus, commuters gain handy options during this major transit leap in the capital.
Ottawa Plans More Transit Growth
The Line 4 debut ignited excitement among folks craving dependable airport travel options. Yet, some riders stay wary because past delays and breakdowns linger in memory.
Indeed, mechanical hiccups struck Line 4 just a week after its big opening. Crews swiftly sidelined one train, briefly slowing trips between South Keys and the airport.
The city eagerly maps out more light-rail expansions for the coming years. Line 1 will stretch eastward from Blair to Trim Station later this year.
Next, Line 1 targets Algonquin College in the southwest by 2026 with confidence. Also, Line 3 aims to link Tunney’s Pasture to Moodie Station in 2027.
These bold plans highlight the capital’s drive for faster and wider transit reach. So, south-end travelers can anticipate even smoother rides as the network expands quickly.
