Line identities

1 2 3 4

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.

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.

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 maps, placed on the platforms, help you identify your location and the train's direction.

Example : If you take Line 1 southbound from Carleton, you'll see the map before entering the platform.

The maps show:

  • Train direction: Southbound, eastbound, or westbound.
  • Next station
  • Transfer points

System design

We’re building 24 new and updated 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 adaptable buildings

Sustainable mobility
