SubscribeLine 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
Colour plays a crucial role in our design. We use bold, eye-catching colours. The colours reflect the energy and vibrancy of our growing city. These colours are used consistently in maps, signage, and schedules.
Intuitive wayfinding is key to seamless navigation. For this reason, we’ve defined distinctive colours for each O-Train line.
This visually striking approach helps riders get familiar with their regular routes. It also lets them identify their desired lines quickly and easily.
Quick facts
- Lines 1 and 2 will keep their existing colours
- Lines 3 and 4 will have brand new colours
- The colours of the bus services will remain the same for consistency
The identity of new O‑Train lines is distinctive, accessible, and user-friendly.

Our approach
We considered accessibility, distinctiveness, and visibility. Unique brands for each line helps 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.
View the system mapStation 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 were designed for effortless recognition. They feature clear, highly visible, and easily identifiable markers.

Direction‑of‑travel line maps
You’ll find these easy-to-use maps as you arrive at the train platform. These signs tell you where you are along the O‑Train line. They let you know whether you’re heading the right way by showing all upcoming stations in your travel direction.
Here's a preview of what you can expect:
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.
To help you navigate easily, this map provides valuable information, such as:
- The train’s direction of travel
- The next station
- Transfer points

- 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

Vibrant, contemporary designs
The stations architecture features abundant use of wood, and glass. This allows natural light to fill the spaces and enhances station security. It also makes it easy for customers to move through the station and provides common areas for riders and nearby residents to enjoy.
The stations will transform into lively community hubs complete with:
- Customer information and services
- Captivating public art
- Accessible public spaces
These stations will blend seamlessly into the surrounding city. You’ll enjoy a diverse range of amenities that cater to the needs of our customers.
Station design features: examples and highlights
Bayview Station
- Two tracks and platforms to provide more flexibility for operations
- Access to both platforms through a partially enclosed walkway to keep you protected from the elements
- Multi-line station with Line 1 platforms on the upper level and Line 2 platforms below

Airport Station

These design features create a safe and accessible experience and make public transit a convenient transportation option.
Revamping public spaces for greener commutes
We are improving station access for nature-friendlier forms of transportation, like walking and cycling. Most stations will also have direct bus connections. This will make it easier to access the O‑Train from farther away.
The system design encourages residents to walk, wheel, bike, or bus to the O-Train. In the new network, 77% of Ottawa's residents will live within 5 km of a station. This could be a 10-minute bus ride, a 20-minute bike ride, or an even shorter trip if you live closer.

Station areas

The O-Train Extension embraces green design principles. Stations beyond Ottawa's urban core harmonize with the local ecosystem. Wildlife-friendly structures, including culverts and passages, let smaller animals safely cross under the rail line. The High Road Bridge, the O-Train's first wildlife crossing, lets larger animals and people go over. The High Road Bridge provides a safe passage for animals, pedestrians and cyclists.
Found near the Greenbelt and Rideau River, it fosters the smooth movement for flora and fauna. This promotes a thriving ecological corridor. The High Road Bridge design also supports future development.
Artfully-clad construction sites
As the O‑Train network expands, we're excited to incorporate Indigenous artwork to beautify construction sites. Nine talented Indigenous artists contributed culturally relevant images under the theme 'Land is Medicine' from their respective territories. Emphasizing the significance of land in Indigenous cultures, these pieces represent healing traditions and diverse cultural themes.
Witness the beauty of these artworks displayed on O‑Train Extension construction hoardings, promoting Indigenous art and artists throughout the city.
Let's honour the Algonquin Anishinabe Nation and all First Nations, Inuit, and Métis peoples who've shaped this land's vibrant history.
