This article is a companion to Travel Times on 504 King: Update to January 2025 published here recently.
This is a long article with increasing levels of detail toward the end. Feel free to bail out, or come back later.
Although problems with severe congestion delaying transit downtown were somewhat reduced by the addition of Traffic Wardens by the City of Toronto in 2024, reliability issues continue to affect service along the King route. The situation illustrates a few of the service design and management challenges for this type of route, and shows how simply reducing congestion will not necessarily provide regular service.
504 King is unusual in having four terminals: Dundas West Station and Dufferin Loop in the west, Broadview Station and Distillery Loop in the east. The TTC only measures service reliability at terminals, but the overlapping 504A and 504B services must blend together to provide the advertised quality.
The 504 shares with other streetcar routes a much wider headway than existed before the pandemic. This is due primarily to the change in vehicle size, and only partly to riding levels. With less frequent service, regular spacing is more important because scheduled gaps between vehicles are already wide, and can get much wider. This is compounded by overlapping services on the 504A (Distillery to Dundas West) and 504B (Broadview to Dufferin). Nothing in the service design or line management ensures that these blend evenly, and the design provides very frequent service only on paper.
The table below compares headways on routes that operated with the shorter CLRV streetcars in January 2019 versus the new Flexitys in January 2025.
| Route and Period | January 2019 | January 2025 |
|---|---|---|
| 501 Queen to Humber | ||
| AM Peak | 4’15” | 10’00” |
| Midday | 4’45” | 9’00” |
| PM Peak | 4’50” | 8’30” |
| Early Evening | 4’30” | 10’00” |
| 506 Carlton | ||
| AM Peak | 5’10” | 10’00” |
| Midday | 5’20” | 10’00” |
| PM Peak | 5’40” | 10’00” |
| Early Evening | 7’10” | 10’00” |
The next table compares headways on routes that were already running Flexitys in 2019. (The Distillery District was originally served by 514 Cherry which ran from Distillery Loop to Dufferin Loop. In October 2018, the service design changed to the 504A/B configuration we have today.) 504 King service is less frequent than in 2019, and even less frequent than in November 2017 when the transit mall was implemented and the line was running with the smaller CLRVs.
512 St. Clair saw a substantial drop in service in May 2023 when headways increased from roughly 6 to 8 minutes. Not long after, the route then went through a long, painful period of bus operation during multiple, overlapping TTC and City projects. TTC plans to restore 6 minute or better service in late 2025. (Yes, you are reading that table correctly: peak service now is about half what it was in 2019.
| Route and Period | January 2019 | January 2025 |
|---|---|---|
| 504 King | ||
| AM Peak | 5’15” on each branch | 8’00” on each branch |
| Midday | 7’00” on each branch | 10’00” on each branch |
| PM Peak | 6’00” on each branch | 10’00” on each branch |
| Early Evening | 6’30” on each branch | 10’00” on each branch |
| 512 St. Clair | ||
| AM Peak | 3’45” | 8’00” |
| Midday | 4’45” | 8’00” |
| PM Peak | 4’10” | 8’00” |
| Early Evening | 6’45” | 8’00” |
Other routes were operating with buses in 2019 or 2025, and they are omitted here although their streetcar service is also less frequent now than it once was.
Although the service capacity in the case of 501 Queen and 506 Carlton is roughly the same allowing for the difference in vehicle size, the situation on 504 King and 512 St. Clair shows a marked reduction of capacity. This is an example of how the TTC is most definitely not back to 100% of pre-covid service, no matter how many media events make that claim.
With a wider scheduled headway, gaps will be wider too if either a vehicle is missing (e.g. a short turn) or vehicles are bunched together. When the scheduled service was frequent, some bunching was inevitable because vehicles were already close together. A management style that worked tolerably for frequent service does not work when fewer, more widely-spaced cars serve a route.
In this article, I will review performance of the 504 King route in January 2025, and show comparative data from earlier periods.
