With all the feeder buses and, in the future, feeder Light Rail services to Toronto’s subway system, capacity is being stretched. The TTC costs about CAD $1.4 billion to operate and ridership is now reaching record levels – ridership on the TTC in 2011 is forecast to be around 483 million rides. This means one thing- more capacity is required.
New trains are coming into service on the busy Yonge-University-Spadina line. These new ‘Rockets’ as they are called are the same dimensions as the older trains but have 10% more space. If you look carefully at the trains, you will see how few seats there are on the trains. This is common in high capacity subway systems where distances travelled from the city are relatively short to medium (say 20 or so km).
As Brisbane becomes a larger city, there are some things that can be done to increase capacity on trains and buses without having to expend huge amounts of money on building new lines or waiting forever for big ticket projects to complete, be funded or be planned for. These non-infrastructure solutions are sadly too often overlooked; making existing infrastructure work more efficiently doesn’t seem to be as sexy as a new piece of busway/railway/subway/Insert High-Cost-Planning-and-Waiting-Forever-Infrastructure of Your Choice Here
In larger cities more people stand on public transport. Fact. Train services that only travel relatively medium to short distances could have internal seating changed to free up more capacity without having to buy more trains or build more tracks. The same principle could also be applied to Brisbane’s existing buses which have a low floor section in the front of the bus. If seating in this low floor front section were changed to 1 by 1 seating or another arrangement, the bus could hold more people, would take longer to fill and leave less people behind.
So the message is simple: For more capacity remove and reorganise the seats.
This post looks at Toronto’s (now superseded) Transit City LRT plan.
Light Rail has become quite popular in Canada- Toronto (Eglinton LRT), Edmonton (ETS) and Calgary (C-Train), Ottawa (Transitway/Busway conversion to LRT) and recently Light Rail was endorsed as the preferred rapid transit mode for Kitchener-Waterloo. The Transit City LRT plan for Toronto was different from the other proposed or existing LRT systems in that it had a more “feeder” function- the purpose was to provide rapid transit to connect people in the suburbs to the main rapid transit artery: the subway system- and in doing so provide mobility for both CBD-bound and cross-town trips. Many of the TTC’s bus routes carry around 40, 000 passengers per day (roughly about 10 million per year), so the capacity of LRT would be a plus here.
There was much debate and controversy over the Transit City LRT plan as it was the brainchild of former Toronto mayor David Miller, who was replaced by now incumbent mayor Rob Ford who ran on a platform espousing subways and portraying LRT as slow streetcars (in earlier posts the difference between LRT and streetcars has been made clearer). A good LRT system can do up to around 10, 000 passengers/hour/direction in Class B ROW and, if built like a subway (Class A ROW), around 20,000 passengers/hour/direction.
Why did the TTC choose LRT, over subways, at least for this plan? Mitch Stambler from TTC service planning identifies the following points:
* Much cheaper than subways, LRT is 4-5 times cheaper than subway which means
* More bang for buck- 4-5 times more rapid transit for the same money
* Class B ROW results in excellent quality service
* Satisfies projected demand required
* Environmental benefits (Toronto has much of its power come from Hydro sources)
* Toronto is not New York, Hong Kong or Berlin– LRT fits the demand required
and is realistic for the city.

What does this mean for Brisbane? Looking past the technology, this blog’s view is that further improvements to the BUZ network should be introduced along with more ambitious priority (full length bus lanes/T2 lanes) along major arterial roads and traffic light priority. This blog’s experience with Brisbane’s buses is that they are quite slow compared to other cities, such as say, Canberra. Rail lines and ferries should be boosted in frequency to knit a ’15-minute frequent’ network around Brisbane, and using the large suburban shopping centres as interchange points, slowly cut back non-BUZ routes to create a feeder-style network, which will provide high frequency in the suburbs, where the people are and also allow people to get from suburb-to-suburb without going to the CBD first. (Try getting from Tarragindi to Yeronga- it takes a whopping 48 minutes to do this using public transport, and up to three bus changes! In a car this might take 10-15 minutes!). Improvement of the orbital 599/598 Great Circle line will also be important to enable cross-town and meet local transport needs.
As this section on Toronto draws towards a close, it would not be complete without a video about Toronto’s CN Tower, and engineering marvel and an international icon of Canada.
Melbourne is knows for the arts, Luna Park, St. Kilda and Flinders Street Station, Sydney is known for The Opera House and the Sydney Harbour Bridge… we’ll get back to you when we figure out what’s iconic about Brisbane – or you can make a suggestion below!
The BrisUrbane Blog has come across a presentation given by the manager of service planning, TTC about what LRT is and isn’t. Here is an abridged transcript, comments have been added by this blog in brackets. It shows well what the TTC had in mind when it was talking about LRT:
Mitch Stambler, Manager, Service Planning, Toronto Transit Commission (TTC)
talking at the Ottawa Light Rail Transit (LRT) technology forum (video link here!)
For a transit system to be categorised as light rail, it has to have all or
most of these characteristics:
- It should operate mostly in an exclusive Right of Way (i.e. Class B or Class A ROW)
- It should have stop spacing of upwards of half a kilometre (500m) or more so that is can achieve average operating speeds of 23-40 km/hr or upwards
- Passengers should be able to board through all doors
- Fare collection should be done off-board or there should be honour fare collection so that we can minimise dwell times (the time the vehicle spends hanging around a stop)
- Vehicles should be multiple unit, double ended so that you can turn around quite quickly and achive high capactity so that you can use centre or side platforms
- Operation of automobiles and traffic should be restricted in terms of turning movements and parking
- There may be grade separations at selected key locations (in other words bridges or tunnels should be used to keep the service separated from car traffic rather than have intersections)
- And you should use signal priority at any at grade signalised intersections (so traffic lights prioritise public transport at normal traffic light intersections)
The reason why I wanted to provide this list is because I want to show you that
Toronto DOES NOT operate Light Rail. (Crowd laughing).
Video: ‘Toronto Fire P343 riding the rails on the St Clair Right of Way’ (efd488, YouTube)
Is emergency vehicle access only limited to busways? The St. Clair right of way (ROW) is probably the closest Toronto gets to having actual LRT; Had Toronto city councillors not forced the TTC to add more stops to the route and had the high-floor, single ended streetcar vehicles and so forth, been replaced with a double ended LRT vehicle with multiple door boarding, the St. Clair ROW could well have qualified as LRT. Due to space restrictions preventing the construction of large medians to separate mixed traffic and transit, the TTC raised up the lanes to be higher than the mixed general traffic lanes so that car drivers would be discouraged from driving in the transit ROW.
The video above shows a City of Toronto fire department making use of the ROW to get its fire trucks past traffic. So is emergency vehicle access only limited to busways? If the LRT tracks are set in continuous concrete then it seems that emergency services- police, fire, ambulance- can indeed make use of LRT ROWs.

Before this blog features the TTC’s former Transit City LRT plan, a word about Toronto’s streetcars and the problems they face due to system design and lack of prioritised right of ways (ROW). Toronto’s streetcar system, like Melbourne’s, is a ‘legacy’ system designed well before car ownership took off. Stops are spaced very close together (a stop about every 250 m) which means the service once you get to the stop is going to be slow. Operation in mixed traffic without dedicated lanes (Class C ROW) interferes with service reliability and limits streetcars speeds to be no faster than the congested traffic in front of it.
It’s obvious that such problems stem from the stop spacing, features of operation (such as front door only boarding) and level of priority given by the class of ROW and not so much because the vehicle has a trolley pole, steel wheels, makes chiming sounds, and is called a streetcar. Simply swapping a unprioritised streetcar stuck in congestion stopping everywhere for a unprioritised bus stuck in congestion stopping everywhere may well cost extra money, but is unlikely to improve service a great deal.
Graham Currie (Department of Civil Enginnering, Monash University) and Amer Shalaby (Department of Civil Enginnering, University of Toronto) in 2006 published a paper titled ‘Success and Challenges in Modernizing Streetcar Systems: Experiences in Melbourne, Australia, and Toronto, Canada‘ [paywall] comparing Melbourne’s Yarra Trams to the TTC’s Streetcar system and looking at the challenges that these ‘legacy’ systems face such as keeping reliability and speed at acceptable levels in the face of growing car congestion.
Indeed, one of the reasons why Bus Rapid Transit (BRT) and Light Rail Transit (LRT) modes were created was to get faster speed and more separation from car congestion by giving vehicles their own dedicated lanes, wider stop spacing, and prioritisation at intersections. So in this sense, BRT and LRT are an intrinsically different style of service to the local stop-everywhere bus and streetcar.
Removing stops to increase speed and giving transit vehicles their own lanes to increase speed, cut the number of vehicles used, and increase reliability is politically charged and difficult because a conscious, public decision to spend money on explicitly prioritising public transport over the car must be made. But if you don’t do it you can expect a much compromised quality of public transport service.
