This article continues a series reviewing the operating speeds of streetcar lines in detail looking at:

• Evolution of travel times on 511 Bathurst from September 2019 to June 2026 by route segment.
• Detailed profiles of operating speeds over the full route for the same months.
• Locations where streetcars spend long dwell times including stops, traffic signals and road congestion.

The two intervals compared here are:

• June 1-5, 2026: This was just before the upheavals of the World Cup period, but without any construction diversions that would distort the data. At this point, red lanes were installed on Bathurst from Bloor to Nassau (north side of Western Hospital), and from Dundas southward.
• January 13-17, 2020: This was early in the operation of 511 Bathurst with the new Flexity streetcars, after the holiday period but before traffic conditions changed with the pandemic in March.

Locations of substantial delays lie mainly south and west of Queen and Bathurst, although the focus on priority has been further north. Some benefits of the red lanes are evident, but the south end of the route needs a detailed review to determine why supposed priority areas on Bathurst and on Fleet are locations for delay.
