The Trillium Line (French: Ligne Trillium) is a diesel light-rail transit (DLRT) service in Ottawa, Ontario, Canada operated by OC Transpo. The line is part of Ottawa's O-Train light rail system.

The present line runs north-south on a railway line, from Bayview to Greenboro, a distance of approximately 8 kilometres (5 mi). It is isolated from road traffic, but shared with other trains; after operating hours the track has been infrequently used by Ottawa Central for freight service to the National Research Council.

Since its opening on October 15, 2001, the Trillium Line hit the 1-millionth rider mark on May 29, 2002, the 5-millionth mark on January 21, 2005, and the 10-million in late 2010.

Until late 2014, the official name of the diesel-powered, north-south line was O-Train. After construction started on a second, east-west light rail line (the Confederation Line) the O-Train name was applied to the entire system, and the north-south line was renamed the "Trillium Line".

Between 2013 and 2015, there was an upgrading of the line, including the complete replacement of the train fleet, in order to cut wait times during peak periods from 15 minutes to 12 minutes and eventually to 8–10 minutes. The upgrade was also a precursor to extending the line southwards by three stations.

The Trillium Line, Ottawa's original O-Train, was introduced in 2001 as a pilot project to provide an alternative to the busways on which Ottawa had long depended exclusively for its high-grade transit service (see Ottawa Rapid Transit).

Until 2015, the system used three diesel-powered Bombardier Transportation Talent BR643 low-floor diesel multiple unit trains. (Currently, the line operates with Alstom Coradia LINT DMU trains.) It is legally considered a mainline railway despite being used for local public transport purposes, and the service it provides is, in terms of its route and service frequency, more like that of an urban railway than a metro or tramway. OC Transpo operates it under the official name ‘Capital Railway’, which appears on the trains along with their regular logo. It was, however, described as ‘light rail’, partly because plans called for it to be extended into Ottawa’s downtown as a tramway-like service, and partly because the Talents, though designed for mainline railways in Europe, are much smaller and lighter than most mainline trains in North America, and do not meet the Association of American Railroads' standards for crash strength. Ottawa is also authorized to run trains with only a single operator and no other crew, something rare on mainline railways in North America.
