This article is an update from a previous item about service capacity, as well as a look at the travel times of Queen cars through downtown and the effect of the King Street Pilot.
Capacity provided on the line continues to be affected by the low availability of the larger ALRVs (articulated streetcars) and their replacement by CLRVs which are only two thirds the size. Peak hour capacities are shown at selected points below.
There is no provision for a capacity increase in the fall schedules, and the best riders can hope for will be that Flexitys will start showing up in weekday service where the ALRVs should be, but have been so absent. On Sunday, September 2, the TTC operated the 501 Queen service almost entirely with Flexitys on a 1-for-1 replacement basis, and it is their intention to do this on weekends from now on.

The chart below extends the one shown in the previous update to show which articulated (larger) cars were in service on 501 Queen during July and August, 2018. The declining number of ALRVs is evident comparing late August to early July.
Travel Times Between Yonge and Bathurst Streets
The charts in this section show the travel times each way between Yonge and Bathurst on Queen for the three-year period September 2015 to August 2018.
Much of the variation in these charts is explained by diversions and special events:
- February 2016: Data missing (gap)
- May to December 2016: All service diverted via Spadina-King-Shaw both ways. The times shown are between Bathurst/King and Yonge/Queen.
- October 2017: All service diverted via Church-King-Spadina both ways. The times shown are between Bathurst/Queen and Yonge/King.
Some increases due to TIFF are visible in September each year, although in 2016 this is masked in the general slowdown caused by the long-running diversion. Note that the eastbound and westbound effects are not identical.
The important point here is that data from months before the pilot when Queen service was not affected by any spillover from King Street are generally the same as the data for the pilot period starting in November 2016.
Here are samples from the PM peak hour of 5-6 pm.
In these charts, four percentiles are tracked:
- The 100th percentile (red) is the highest observed travel time for cars entering the zone (westbound crossing Yonge, or eastbound crossing Bathurst) during the hour in question, even if only one car takes this long (typically the first car held by a delay).
- The 85th percentile (orange) is the time required for most cars to make the trip.
- The 50th percentile (green) is the median time required. Half of the cars were faster, half were slower than this value.
- The 25th percentile (purple) is the bottom (best) quartile of travel times.
If the four lines are clustered together, there is only a small spread in the travel times. Where the values fall to zero, typically there was either a major delay, or a diversion that prevented any cars from entering the zone during the hour.
