The TTC continues to issue notices of Restricted Speed Zones (RSZ) for the subway system. Some appear and disappear in short order, while others are extremely long-lived. I have been tracking the status of these since early 2024, and the charts below show where and when the zones were in place.
Some areas have had RSZs in place continuously for over a year. The TTC has not given any indication of when these will be repaired, although the list has thinned out over the past year.
The departing interim CEO has claimed that 12 RSZs will be a normal situation. This might be credible if problem areas appeared and disappeared quickly, but this is only the case for some of the zones listed here.
A related problem is that some of these areas have been in bad shape for an extended period thanks to deferred maintenance and the complexity of repairs. TTC management has mused about extended shutdowns to attack these problems, but without any specifics, and especially regarding replacement services.
Where the symbols “>” or “<” are used, the RSZ is only in one direction. Where “<>” is used, the zone applies both ways. The charts are broken by year with 2024 on the top, 2025 below. The dates correspond to my visits to the website.
