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.
