For the former railway station in Carleton-sur-Mer, Quebec, see Carleton station (Quebec).

Carleton station is an O-Train light rail station located in the center of the Carleton University campus in Ottawa, Ontario. The station is served by Line 2, which began service in 2001, and is between Dow's Lake station to the north and Mooney's Bay station to the south. Along with the rest of the Trillium Line, the station closed on May 3, 2020, for the extension of the line and an upgrade of the station. The station re-opened on January 6, 2025.

History

The station in 2005

A Bombardier Talent train at Carleton station in 2008, before the fleet was replaced in 2015 and the station upgraded in 2017.

Carleton station was previously the only O-Train station along the Trillium Line with separate tracks and platforms for each direction, in order to allow the two trains working the otherwise (formerly) single-track line at any given time to pass. Since service upgrades in 2014-2015, and the ongoing O-Train South expansion project (Stage 2), more passing tracks have been added to the line. The station was upgraded in 2017 to accommodate the installations of fare gates and shelters parallel to the existing platforms, replacing the previous Proof-of-payment system.

Stage 2 expansion and upgrades

South of the station, the line crosses over the Rideau River on a bridge, which was refurbished during Stage 2. As part of the Stage 2 South expansion, the southernmost pedestrian underpass linking Richcraft Hall and Pigiarvik was rehabilitated, and the main pedestrian underpass located between the station platforms and the Maintenance Building was demolished and replaced with a new structure double the length of the original. During Stage 2, a short tunnel was dug perpendicular to the platforms at their north end. Although it is currently not connected, in the near-to-medium-term future it will provide a direct, weather-protected connection between the station and the Carleton University tunnel system; likely to be connected to the Minto CASE in the building's later expansion. In the 2023 Campus Master Plan update and the 2019 Carleton University Transportation Strategy, the university included plans to build a bus loop or transit hub on the eastern side of the station, in the footprint of existing Parking Lot P4- and relocating all bus connections and bus–train transfers to that area.^[1][2] Pending approval by the City of Ottawa, Carleton plans to connect the transit hub directly to the northbound platform of the train station, providing an additional fare-paid access point for the community.
