501 Queen: Service Capacity with Low-Floor Streetcars (Updated)

Updated June 7, 2019 at 6:45 am: Charts showing capacity of service operated from September 2015 to May 2019 have been added at the end of the article.

For several months, the proportion of service on 501 Queen provided by the new low-floor Flexitys has been rising as the TTC shifts this route to the new fleet. The effect has been that service capacity actually provided has been rising with the larger Flexitys replacing smaller CLRVs on a 1:1 basis. This will change on June 23 with new schedules as discussed in a previous article.

This post reviews the actual capacity provided at certain times and locations on 501 Queen and compares this with the scheduled service that will go into effect with an all-Flexity fleet.

The source data are the TTC’s vehicle tracking records. For each screenline where capacity is calculated, the number and type of vehicles crossing the line is multiplied by the vehicle capacity to determine the actual hourly capacity provided. These values vary from day to day, but the overall pattern of route capacity is easily seen in the charts. Service design capacities of 74 and 130 were used for CLRVs and Flexitys respectively. Although the cars can and do carry more riders, service design is (or at least should be) based on a crowding level where riders have some ability to move around and dwell times are not driven up by delays as people fight their way into and out of vehicles.

One factor in the changing capacity on Queen, by contrast with King, is that as Flexitys started to appear in service, they tended to¬† be dispatched in bunches so that there would be many of the larger cars in a row. This has the effect of making the capacity bump uneven by time and location depending on where the “parade” of Flexity cars would be. When service converts to all Flexity¬† on a wider headway, the change in service capacity will vary, but in all cases it will decrease because there will be about 1/3 fewer cars/hour than there are today.

The table below compares the scheduled capacity before and after the change assuming all “old” service is provided by CLRVs and all “new” service by Flexitys. On paper, there will be more capacity with the new schedule. However, the actual service provided today, and for some time on 501 Queen, is higher than the all-CLRV level. Riders will experience both a considerable widening of headways and a reduction of service capacity relative to what they have had in 2019 to date. It is no secret, based on the King Street experience, that there is latent demand for more capacity on major transit routes like this.

Existing Schedule New Schedule
Service Design Vehicle CLRV (74 passengers) Flexity (130 passengers)
AM Peak Headway 4’15” (255 secs) 6’30” (390 secs)
AM Peak Cars/Hour 14.1 9.23
AM Peak Capacity 1,045 1,200
PM Peak Headway 4’50” (290 secs) 6’50” (410 secs)
PM Peak Cars/Hour 12.4 8.8
PM Peak Capacity 920 1,140

In the charts below, the actual capacity provided by the mix of CLRV and Flexity service is regularly above 1,200 passengers/hour, and the new schedule represents a service cut. The only saving grace is that the TTC plans to operate three peak period trips in each direction with buses (adding roughly 150 spaces to the peak-within-peak period) and keep a few “run as directed” cars in reserve. When the actual operating results for June and July are available, we will see exactly what service was provided.

TTC Service Changes Effective June 23, 2019

The TTC will make several changes in its service on June 23. Many of these are the usual summer service reductions, but others will see changes for construction projects, to improve reliability on some routes, and to redeploy the streetcar fleet.

Subway

On 1 Yonge-University-Spadina, the dispatching of trains will change to increase the use of the north hostler track and exit from Wilson Yard (all days), and to restore the full capacity of Davisville Yard following expansion of the carhouse (weekdays).

On 2 Bloor-Danforth, a gap train will be dispatched from Greenwood or Keele Yard in the AM and PM peak as needed to fill service gaps. There will also be the usual summer service reduction on this line.

On both routes, crew procedures at Finch, Vaughan, Kipling and Kennedy will be changed to single step-back operation.

Streetcars

The 501 Queen car will be formally scheduled as a low-floor route entirely with new cars. In recognition of their larger capacity, headways will be widened somewhat, but not on the scale Toronto saw when the two-section ALRVs replaced the CLRVs on a 2:3 ratio with correspondingly wider headways. Although in theory the scheduled capacity remains the same, the actual capacity could fall because new larger cars have already been operating on the shorter CLRV headways. I will explore this in a separate article.

Night service will be improved on 301 Queen to reduce overnight storage needs with the large number of new cars now on the property together with remnants of the old fleet, and the partial closure of Roncesvalles Carhouse for reconstruction. This continues a change introduced on 304 King in May.

CLRVs will continue to operate on the Long Branch segment of the route. This is expected to change to low-floor operation in September. The peak period trippers that run through from Long Branch to/from downtown will be dropped, but will return in the September schedules.

The 511 Bathurst route will revert to streetcar operation. The exact mix of cars will depend on availability and day-to-day decisions about allocation. The service memo shows a small allocation of ALRVs to the route, but these could turn out to be Flexitys instead just as happened on 501 Queen. (Click to expand the table below.)

Leslie & Eglinton

For the summer months, Leslie Street will be closed at Eglinton, and a temporary loop will be created north of the intersection. This will be used by 51 Leslie and by some of the 54 Lawrence East service. Weekdays from 5:15 am to 9 pm, and weekends from 8 am to 7 pm, the Starspray and Orton Park branches will terminate at the Leslie/Eglinton loop, and there will be a separate service running from Eglinton Station to Lawrence East Station via Don Mills & Eglinton. Outside of these periods, the Starspray and Orton Park services will run to Eglinton Station via Don Mills, and a supplementary shuttle will run from Leslie/Eglinton to Lawrence/Don Mills as part of the 51 Leslie route.

All 51 Leslie service will terminate at Leslie/Eglinton.

The 954 Lawrence East Express is not affected.

Service on 34C Eglinton East to Flemingdon Park will be increased slightly to offset changes to 54 Lawrence East.

See the linked spreadsheet for details of the various routes, headways and hours of service.

Lawrence Station

Because of construction at Lawrence Station, part of the bus loop will be closed for paving and the 52/952 Lawrence services will loop via the east side of the station. Service on 124 Sunnybrook and 162 Lawrence-Donway will be extended west and north to Roe Loop on Avenue Road. Transfers between these routes will move to surface stops.

Wellesley Station

Construction at Wellesley Station will complete and the 94 Wellesley will return to its normal operation with its eastern branch terminating there rather than at Queen’s Park.

Royal York Station

Buses were planned to return to Royal York Station on May 24, but the schedules will not formally be revised until August. Interlining of 15 Evans with 48 Rathburn, and of 73 Royal York and 76 Royal York South, will continue until then.

Bay Bus

Service on the 6B short turn at Bloor will be discontinued during the peak period and all buses will run north to Dupont.

Dufferin Bus

All service will terminate at Dufferin Loop rather than at Princes Gates due to frequent summer events that make bus operation through Exhibition Place difficult.

Road Construction in Scarborough

Several routes will be affected by road construction projects.

Danforth Road from St. Clair to Danforth Avenue:

  • 113 Danforth

Midland Avenue from Danforth to Lawrence:

  • 20 Cliffside
  • 57 Midland

Brimley Road from Progress to Huntingwood:

  • 21 Brimley

Huntingwood Drive from Kennedy to Brimley:

  • 169B Huntingwood
