O-Train South Extension

Overview

The Trillium Line South extension is one of the three major extensions to Ottawa’s light rail transit system. This extension will see the Trillium Line continue from Greenboro Station to Limebank Road in Riverside South, along with a link to the Ottawa Macdonald-Cartier International Airport. Revenue service for this extension is planned for 2022.

Highlights

  • Construction of two new stations and the extension of five station platforms on the existing Trillium Line to accommodate longer trains with additional capacity.
  • Four new stations along the new extension and two new stations along the 4-kilometre Airport Link.
  • Construction of a new Walkley Yard Maintenance and Storage Facility (MSF).
  • Delivery of new municipal infrastructure, including two new pedestrian bridges to improve connectivity along the alignment through multiuse pathways (MUPs).
  • Maintenance of both the existing Trillium Line and the extension for 27 years.

Extension Description

The Trillium Line extension includes eight new stations and sixteen additional kilometres of track from Greenboro to Limebank in Riverside South, with passing tracks at South Keys and double tracked south of Leitrim to Limebank Road. The proposed plan would essentially extend the City’s LRT reach to Limebank Road in Riverside South, bringing southern communities such as Manotick, Findlay Creek, Greely and Osgoode much closer to this high quality transit service. The overall alignment for the most part follows the existing CPR alignment up to Earl Armstrong Road where it curves west to Limebank Road.

The extension of the Trillium Line, new stations and structures for grade separation will allow for future conversion to twin-track electric LRT and will be built to accommodate the planned widening of both the Airport Parkway and Lester Road.

O-Train South Extension Construction Activities

Corso Italia Station

Corso Italia Station will be a new station located north of Gladstone Avenue. A singlefare paid entrance will be centred upon the alignment with a new station plaza integrated with the existing Gladstone Avenue Bridge. The public plaza design will include a mix zone near Gladstone Avenue to allow the mixing of pedestrians and cyclist utilizing the north-south MUP in a controlled manner, while the eastern edge of the public plaza will be separated from the north-south MUP with landscape and urban design elements to prevent the uncontrolled mixing of pedestrian and cyclists within in the plaza.

The station is being designed to protect for a second level to ensure overhead connections are supported from future development on both the east and west side of Corso Italia Station.

Leitrim Station

Leitrim Station is an existing bus station and park and ride facility located south of Leitrim Road. The new Leitrim Station will be a line and transfer station. The existing park and ride will be expanded to 330 spaces initially and designed to facilitate a capacity of 925 spaces.

The new station will have a minimum of one fare paid entrance with access to the park and ride. It will be designed and constructed to allow the bus platform to remain accessible to the public while securing the train platform during non-operating hours.

 

Limebank Station

Limebank Station will be a new terminal station located west of Limebank Road, south of Earl Armstrong Road and east of Main Street. The station will have a minimum one fare paid entrance with access to Main Street, the north east-west Connector Road, and the future south east-west Connector Road.

It will be designed as an urban station with direct access to the on-street bus facility located to the north of the alignment.

Uplands Station

Uplands Station will be a new station located east of Uplands Drive adjacent to the EY Centre. The station will have one fare paid entrance serving the EY Centre and future development north of the alignment. The plaza and site will be designed to accommodate EY Centre event patrons. The access road will be realigned directly in front of the EY Centre and the existing parking will be reconfigured to allow for direct sightlines and access to the station from the EY Centre entrance.

Airport Station

Airport Station is a new station at the Macdonald-Cartier International Airport and will represent the terminus of the Airport Link. It will be a new elevated station located adjacent to the airport departure roadway and the airport passenger terminal building. The entrance and lounge will be an extension of the airport terminal building and the station platform will be at the same elevation as the third level of the airport passenger terminal building.

The design of the station will be closely co-ordinated with the Airport Authority throughout design development as they will extend the existing airport passenger terminal structure to the station. The station, platform, guideway and guideway structures will be constructed to allow the Airport Authority to construct the airport passenger terminal expansion, including the entrance and lounge directly, together.

Walkley Maintenance and Storage Facility (MSF)

Trillium Line vehicles will be cleaned, inspected, maintained, washed, stored and operated from Walkley Yard Maintenance and Storage Facility (MSF).  A new facility is being built to perform maintenance on the seven Stadler FLIRT vehicles being procured to support the extension and the existing six Alstom Coradia Lint Trains.
