This post continues previous reviews of the map and lists of reduced speed zones (RSZ) on the TTC subway with snapshots of the status of Lines 1 and 2 from mid-October 2025 to mid-March 2026.
The charts below are adapted from maps that are updated regularly on the TTC’s Reduced Speed Zone page.
The total number of zones sits persistently at about a dozen. Although some disappear fairly quickly, others replace them. Some are long-standing zones that are more challenging to repair in winter weather.
In the coloured boxes, the arrows indicate the affected direction of travel with “<>” meaning both ways.
The TTC is working hard, I understand, to get the system in the best shape possible for the World Cup events from mid June to early July. Whether they will achieve this remains to be seen.
One issue is the timing of the usual Spring system inspection of rail condition and track geometry. Will the results of this inform current slow orders, or will this be carefully “parked” so that new slow orders do not appear until after the big event?
The current orders have target repair dates in March and April, with 4 of 14 showing “TBA” I will return to this topic in early June.
Updated March 20, 2026: Following the “more” break are comparisons of the detailed explanation of RSZs in effect at the start of this period (Oct 17) and end (Mar 18).
The charts below compare the RSZ lists from October 17, 2025 (left column) to March 18, 2026 (right column). In some cases the same areas appear in both lists, but for most the entries are different.

Have they been able to produce a streetcar network version of this report yet? Or are we still in the dark…
Steve: They have never produced such a report.

Whats the problem with the one from Eglinton to Davisville been there for a long time?
Steve: In common with some other areas where track is out in the open, the foundation under the track is in poor shape, and it is hard to keep the track in good alignment. This problem has existed for years. When Andy Byford was CEO, he talked of the need for complete reconstruction, but this would require closing the line for an extended period, not just over a weekend. Repairs are done to make do from time to time.

To reduce the length of time needed to do the maintenance within the speed zones needs an increase of workers. However, to increase the number of workers means an increase in expenditure needed to do so. Unfortunately, they do the work with the MINIMUM number of workers to save money. The TTC remains underfunded compared to Europe and Asia for maintenance and operations.
Steve: Some work is constrained by the availability of work cars to support things like material delivery and hoisting. This is a result of TTC’s deferral of some car acquisitions to reduce capital spending in the Tory/Leary era.

Can you do the same thing you did with August 2025 please?
Steve: I have added the details of RSZs for October 17 and March 18 to the article. I hope this is what you are looking for.

There was that brief moment in time last year when they had a little chart showing an (inaccurate) list of slow zones on the streetcar system. I haven’t seen it since.
