Our design uses bold, eye-catching colours that play a crucial role.

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:
New naming examples
These examples demonstrate our approach to naming the new stations:

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
