O-Train West extension
In this phase, we’re extending Line 1 west to Algonquin Station and adding a new Line 3 that connects to Moodie Station.
Line identities
We carefully designed the identity of rail lines to simplify wayfinding and enhance recognition. This helps customers develop navigation muscle memory. The future O-Train network ensures a seamless and intuitive experience by:
- Clearly distinguishing the lines using different colours
- Creating meaningful, memorable, and practical station names
- Providing consistent and coherent signage
Line colours
Our design uses bold, eye-catching colours that play a crucial role.
These colours reflect our city’s energy and vibrancy and are consistent across maps, signage, and schedules.
Distinctive colours for each O-Train line support intuitive wayfinding and seamless navigation.

Key factors
- Unique line colours for easy differentiation. We’ve added numbered icons for more clarity.
- Accessibility:
- High contrast and colour-blind friendly
- Line identities chosen with extensive stakeholder input, including the CNIB
- Colours are adaptable across all formats they’re displayed including:
- Digital screens
- Maps
- Printed signs
- Station signs

- Backlit signs
- Alignment with service design (how lines would be shown in context):
- Lines 1 & 3 mostly run parallel
- Line 4 connecting to the airport is linked with Line 2
- Numbers and colours that are easy to identify and remember
Our approach
We considered accessibility, distinctiveness, and visibility. Unique brands for each line help you spot your lines more easily. Bold colours remain visible under various lighting conditions.
The result is a user-friendly and visually appealing wayfinding system. It will allow riders to explore Ottawa with ease.

Station names
Choosing the right station names is crucial to help riders navigate to their destinations.
We selected the names for new O-Train stations in consultation with:
- Ward Councillors
- Members of the public
- A working group led by the Transit Commission Chair
While selecting these names, we ensured they were:
- Geographically meaningful
- Easy to understand in both English and French
- Easy to pronounce and write
- Unique and distinct from other stations and city locations
- Consistent with Transitway station names
New naming examples
These examples demonstrate our approach to naming the new stations:
Carling Station becomes Dow’s Lake Station
Renamed to highlight nearby Dow's Lake and the surrounding neighbourhood.
Dow's Lake Station
Dominion Station becomes Kichi Zìbì Station
- Aligned with nearby Kitchissippi Lookout
- Named after adjacent Ottawa River
- Uses an Algonquin spelling for added cultural relevance
Station signage
Station entrance signs
O-Train Extension station entrance signs will feature distinct colours and numbers for improved visibility.
- Lincoln Fields Station, serving Lines 1 & 3, features a red circle with a white "1" and a gold circle with a white "3".
- Bayshore Station, served by Line 3, displays a gold circle with a white "3".
- South Keys Station, on Lines 2 & 4, reveals a green circle with a white "2" and a blue circle with a white "4".
The signs are designed for effortless recognition. They feature clear, highly visible, and easily identifiable markers.
Direction-of-travel line maps
These easy-to-use maps are located on train platforms.
They show you where you are along the O-Train line and help you know whether you're heading in the right direction by displaying all upcoming stations.
If you’re heading south on Line 2 at Carleton Station, you’ll see the map just before you enter the platform.
Line 2 is shown as a white number 2 inside a green circle, and a green line on the map.
This map provides valuable information, such as:
- The train’s direction of travel
- The next station
- Transfer points

System design
We’re building 24 new stations along the entire extended O-Train network. These stations will connect neighbourhoods and improve access for many residents.
Our ambitious green approach focuses on:
- Low carbon-impact construction
- Energy efficiency
- Long-lasting and adaptable buildings
Enhanced connectivity for a vibrant community
The O-Train Extension project goes beyond new stations and tracks. We're rejuvenating public spaces and building new pathways. These facilities seamlessly fit into the surrounding community to enhance the quality of life for locals.
Promoting active transportation
We’re investing roughly $20 million in multi-use pathways (MUPs), cycle-tracks, and pedestrian bridges. These will enrich our City's vast pedestrian and cyclist network. This investment improves access across our network.
O‑Train South extension
- A 13.6-km multi-use pathway linking South Keys and Bowesville stations
- A 60-metre pedestrian and cycling bridge over the Rideau River at Carleton University
- An 80-metre pedestrian and cycling bridge above Hunt Club Road, linked to existing multi-use pathways
- A 60-metre connection to Bayview Station from the future Trinity development on Albert Street
- A wildlife corridor where High Road crosses the railway. This connects natural areas separated by road and tracks.
O‑Train East extension
- A new pedestrian bridge over Green’s Creek linking to the Greenbelt pathways along the Sir George-Étienne Cartier Parkway
- Multi-use pathways leading toward the Jeanne d’Arc Bridge from both the north (Fortune Drive) and south (eastbound on-ramp)
- Multi-use pathways, sidewalks, and cycle tracks to improve access and safety for pedestrians and cyclists around stations
- Reconfiguration of roads and bridges (such as the Jeanne d'Arc Bridge) to enhance safety in station areas
- A 2.7-km multi-use pathway between Blair and Montréal stations, offering a key active transportation link between Ottawa's eastern communities and downtown
O‑Train West extension
