Service Restoration After Morning Disruption
Ottawa's O-Train Line 4 has successfully resumed operations following a mechanical issue that temporarily disrupted service to the Ottawa International Airport. The problem occurred on the morning of November 10, 2025, affecting the crucial connection between South Keys station and the airport terminal.
The disruption began in the early hours, causing inconvenience to travelers attempting to reach their flights and airport employees commuting to work. OC Transpo officials confirmed that the mechanical problem was identified and resolved by approximately 10:38 AM EST, allowing full service restoration along the entire Line 4 route.
Details of the Mechanical Problem
While specific technical details about the mechanical failure haven't been fully disclosed, the issue involved one of the Alstom LINT trains that operate on the airport spur line. These trains have been serving the route since Line 4's inauguration, providing direct rail access to Canada's seventh-busiest airport.
The affected train was temporarily removed from service for inspection and repairs, while other vehicles maintained partial service where possible. Maintenance crews worked diligently to diagnose and fix the problem, minimizing the disruption duration during a busy travel period.
Impact on Ottawa Travelers
The temporary service suspension forced many airport-bound passengers to seek alternative transportation options, including taxis, rideshares, and bus connections. The timing was particularly challenging given the morning rush hour and the typical flow of business travelers catching early flights.
Regular Line 4 users expressed relief when service resumed, noting the importance of reliable airport transportation for a city that serves as the nation's capital. The direct train connection has become increasingly popular since its introduction, offering a convenient alternative to driving and parking at the airport.
OC Transpo representatives emphasized their commitment to maintaining service reliability and apologized for any inconvenience caused to passengers. They also reminded travelers that service alerts and real-time updates are available through the OC Transpo mobile app and website for future reference.
