TTC subway maps just got a major change

If you've taken a ride on the TTC recently, you might've noticed a much simpler map hanging above the doors on your train.

That's because the transit agency has been expanding its use of single-line subway maps, or diagrams that show only the line you're riding as opposed to the entire transit network. The maps first appeared on Line 2 back in 2019, and displayed stations along a single route, with transfer points marked by small icons.

Recently, some riders have spotted the same style of map on Line 1 trains, with connection points to the forthcoming Eglinton Crosstown LRT marked throughout.

In 2019, the debut of the single-line maps caused mixed reactions, with some arguing that the maps were easier to follow, while others pointed out that tourists or newcomers might not understand how Toronto's transit lines connect.

Following the backlash, TTC's Customer Service account emphasized that the single-line maps were not meant to replace full-system maps, and that comprehensive maps of the entire subway and streetcar network were still available inside trains and displayed in larger frames near the door.

Single-line maps are used by numerous transit systems worldwide, including in cities such as Tokyo and London, which rely on simplified maps in vehicles and reserve full network maps for larger displays and stations.

TTC spokesperson Stuart Green told blogTO that the single-map rollout is part of a broader update to onboard signage across the transit system.

"In addition to our full subway/light rail maps over the doors, we have added an additional line map for Line 1, Line 2, Line 4, alternating the two map products over the doors within a train," Green explained.

"We've had this on Line 2 since 2019 and are introducing it to Line 1 and Line 4 with the updates for Line 5 and Line 6."

Green also clarified that the transit agency is continuing to install more extensive maps, including those for subway, light rail, and streetcars, in advertising frames in the trains that are portrait style.

"We can expect these to be rolled out to the TRs (Toronto Rocket trains) on Line 1 and Line 4, T1s (T1-series subway trains) on Line 2 in the next couple of months."
