Line 2 (French: Ligne 2), also known as the Trillium Line (French: Ligne Trillium), is a 19-kilometre (12 mi) diesel light rail line in Ottawa, Ontario, Canada. Operated by OC Transpo, it runs north–south between Bayview and Limebank stations, using main line trains.

The first line in the O-Train system, Line 2 opened on October 15, 2001. It operates on a dedicated right-of-way with a mix of single and double-track sections. Although it serves as a public transit line, Line 2 is legally classified as a federally regulated mainline railway. It operates under the official name "Capital Railway", which appears on the trains alongside the O-Train logo.

Service on Line 2 has evolved over time. From October 2001 to March 2015, trains operated every 15 minutes on an 8-kilometre (5 mi) route between Bayview and Greenboro using three-module Bombardier Talent trains. In March 2015, the line switched to two-module Alstom LINT trains, with service frequency improving to every 12 minutes.

May 2020 marked the shutdown of the line for the Stage 2 expansion project. Originally expected to be completed by September 2022, service resumed on January 6, 2025. The expanded 19-kilometre (12 mi) line now extends to Limebank, with trains running every 12 minutes using either four-module Stadler FLIRT trains or coupled pairs of two-module Alstom LINT trains.
