If you've noticed that getting to where you're going in Toronto on the TTC has gotten a heck of a lot slower this week, you're not alone, as riders are already feeling the impacts of some recent service changes — and grumbling about it, naturally.

Now that dedicated bus lanes are coming to Spadina Avenue to help alleviate the nightmarish backups caused during streetcar track replacement work along the thoroughfare, the next big issue delaying commuters in the city is new reduced speed zones implemented along multiple subway lines on Monday.

Awesome how 1/2 of line 1 on the TTC is so slow as to be barely functional. @TTCnotices there is zero incentive to use the service for anyone with the ability to drive,

In these areas, operators must slow trains down to a crawl — 15 km/h or even less vs. the usual 40-50 km/h — in light of track issues that require urgent state-of-good-repair maintenance and could present safety issues if vehicles were to operate at full speed.

These fact that commuters have been dealing with the measure along various parts of the network on a rolling basis for months is what's driving many to frustration, especially given the fact that this latest round appears to be the worst so far, covering around half of Line 1 alone.

I take the subway from Sherbourne to VMC three days a week and it does feel agonizingly slow on Line 1. What an embarrassment for this city and the #TTC. #TOpoli

The TTC advises customers as of Monday to "plan ahead and consider the additional time they may need for their trips" given that trains will be forced to slow down to less than a third of their speed in the following areas:

Line 1 (Yonge-University)

• Both ways from St. Andrew to Union
• Both ways from St. Clair to Davisville
• Both ways from St. Clair West to Dupont
• Both ways from Spadina to St. George
• Both ways from Wellesley to Bloor
• Both ways from Wilson to Yorkdale
• Both ways from Yorkdale to Lawrence West
• Northbound from Bloor to Rosedale
• Northbound from Museum to St. George
• Northbound from North York Centre to Finch
• Northbound from St. Clair West to Eglinton West
• Northbound from Wilson to Sheppard West
• Southbound from King to Union
• Southbound from Lawrence West to Glencairn
• Southbound from North York Centre to Sheppard 
• Southbound from St. Clair to Summerhill

Line 2 (Bloor-Danforth)

• Both ways from Victoria Park to Warden
• Both ways from Warden to Kennedy
• Eastbound from Coxwell to Woodbine
• Westbound from Jane to Old Mill

(2/2) We have a TTC board that has no concept of the state of affairs for routine maintenance and has been distracted by the search for funding for new trains. Meanwhile the infrastructure they run on falls apart. Leary's legacy.

With no end date mentioned, residents will have to keep an eye on the TTC's website and social media to find out when service along problem segments gradually returns to normal — which will unfortunately only last until the next spate of zones is announced.
