Responding to: If at-grade light rail does the job for Calgary, it will for Surrey too – South Fraser Blog
I was drawn to South Fraser Blog a couple of weeks ago when the webmaster commented on the concerns raised by a Township of Langley engineer over the proposed Light Rail system in Surrey. It prompted the response on this blog (Langley and Legitimacy on Light Rail Concerns), which noted numerous fallacies in the SFB article, many common and repeated among Lower Mainland LRT advocates.
Today, SFB caught my attention again with a new headline on the website declaring adamantly and proudly that “If at-grade light rail does the job for Calgary, it will for Surrey too“, a result of the webmaster (Nathan Pachal) recently visiting Calgary. Pictures are included of the Calgary LRT system, in an attempt to set an example for Surrey.
However, I immediately found many reasons to the contrary. As a first, it should be noteworthy that most of the observation wasn’t centered on the newest-opened line on the system.
Opened at the end of 2012 and adding 8.2km, the newest LRT line in Calgary is almost entirely grade-separated (including a prominent elevated segment and station), which likely wouldn’t have served the S.F.B.’s purposes to showcase at-grade rail very well at all.
And yet, the West LRT is a shining example of how Calgary has mandated its future build-out of LRT. Like many cities, Calgary has realized that more grade-separation is key to making rail rapid transit reliable, safe and competitive. Which is why the new West LRT resembles a SkyTrain extension.
Differences in context and right-of-way
As I’ve mentioned in past write-ups on the proposed Surrey LRT system, one of the things I feel is among the biggest issues is the choice on how the proposed LRT system is going to be built. All 27km of the LRT right-of-way (R.O.W.) will be at-grade, on-street, and in the middle of the street – interfacing with vehicles and pedestrians, and operating at the speed of surrounding traffic.
Calgary’s LRT system is not designed in this fashion at all. A comparative survey of LRT systems (pg. 5) measured that 93% of the system is placed on a private, segregated R.O.W. where the speed of trains exceeds 35 miles per hour (60 km/h). There will be no parts of the Surrey LRT that will be operating like this, as the maximum speed limit on city streets is 60km/h. It is atrocious to be trying to draw a comparison between two completely different types of LRT.
Unfortunately, LRT advocates have few systems to draw appropriate comparisons with. In the same aforementioned survey, all of the compared systems operate largely in either fully exclusive R.O.W.s, or other semi-separated ones at over 60km/h – making none of them comparable to the proposed system for Surrey.
These critical details are often forgotten by the Lower Mainland’s light rail advocates, because of the broad scope of systems that are called “light rail” but aren’t necessarily at all comparable.
Glimpsing Calgary’s Light Rail performance
Calgary light rail system provides consistent travel times. In Downtown Calgary, signals are timed to allow the smooth flow for light rail riders, cyclists, pedestrians, and motorists.
(Claim on South Fraser Blog)
The South Fraser Blog reasons that the C-Train’s performance is “consistent” and so will meet the standards of Surrey transit riders. Firstly, I think it’s important that claims like these get some sort of back-up so as to give readers a better idea of what’s being compared, but a link to any information is markedly absent.
So I decided to track down some of the data myself. This is what a 2010 study on the C-Train’s reliability has said about the C-Train’s (in)ability to run on-time:
Due to many issues in LRT operations, the target headway is not achieved regularly. Trains are often delayed, and the level of service is not considered satisfactory by many passengers.
The worst delays on the system happen as the lines pass through 7th Avenue in the City Centre, which is touted by S.F.B. for its on-street alignment. Despite the claimed reliability of the traffic signal sync system, 25 to 30% of all trains in both directions are delayed by more than 3 minutes.
The study does not account for technical issues like stuck doors or signal breakdowns, or for service disruptions caused by closed tracks and accidents – it is meant to measure the system’s day-to-day performance, something that’s generally not considered newsworthy as it’s what Calgarians are used to.
That means that the major incidents that can and do make the news come on top of this already not-so-stellar performance.
And with C-Train riders having to deal with as much as 57 major delays within a single month, many of them have been left relatively miserable.
Regular train rider Heather Laird says @calgarytransit has become her warning beacon for when to ride and when to drive to her job downtown.
“I keep a close eye on Twitter in the morning — delays have become so common we’re used to it.”
On-street running or on-street shoehorning?
Along 36 St NE, light rail traffic is prioritized at intersections.
(South Fraser Blog)
There’s prominent mention of the Northeast LRT’s 36 St NE section, which technically runs in the middle of a road, making it easier to draw comparisons with the proposed systems here in the South of Fraser. For numerous reasons, I still think this isn’t the case.
This is what the Northeast LRT line actually looks like:
36 St NE is busy, and is basically a highway. In order to “prioritize” LRT, there is a requirement of lights, crossing arms and bells at all crossings, and there are dual left turn lanes at the majority of intersections to accommodate for the lengthier train crossing delays. The result is the LRT on 36 St NE looks nothing like an urban tram system, but similar to other Calgary LRT lines placed in freeway medians – with intersections instead.
This isn’t an “on-street LRT”: this is an LRT, with its right-of-way shoehorned into a middle of the street, sharing none of the characteristics of typical on-street tram systems and completely different from the proposal for Surrey.
You do not even cross the street to access station platforms – all stations are accessed by pedestrian overpasses, with stairs or long circular ramps. There is virtually no community integration, and everything requires twice the land footprint of anything that would be permissible in Surrey. The ballasted track LRT R.O.W. is over 4 lanes wide at any point on the corridor.
It’s no coincidence that the S.F.B. article did not include any pictures of 36 St NE. Doing so would paint a picture of LRT that is relatively unattractive.
The confusing context of “LRT”
Light rail supporters mix “LRT” and “tram” statistics interchangeably, thus the arguments made by supporters are quite flawed: the main problem with pro-LRT activists is that the broad scope of LRT systems allows them to take bits and pieces in their argument that do not add up to the whole.
The fact that Light Rail systems come in many different shapes and sizes was first pointed out by the “UBC SkyTrain” advocacy group 6 years ago, and has been ignored by the transit community at-large ever since.
Light Rail has a confusing context. While the many similar systems that are branded as “Light Rail” do share several characteristics, I think there’s a need to pay attention to the key differences in design of these systems. What might work well for a certain LRT system may not work well at all in the other.
One of the reasons I have remained in opposition of a Surrey LRT is because of the many issues that will stem from choices in design and lack of foresight (I recently wrote on the fallacies of a new city study attempting to justify LRT, [SEE HERE]). The Calgary’s C-Train was built in a context that didn’t have these issues from the very beginning. R.O.W.s were pre-planned years before construction, and were largely located off of city streets.
But the differences are not just in specifics in design. It must also be considered that they extend to what roles the transit system is playing in a city.
C-Trains run less frequently than our driver-less SkyTrains, especially during off-peak hours and on weekends, limiting their ability to foster transit-oriented communities with people living transit-coherent lifestyles.
As a result, C-Train is most effective at replacing cars for that final commute into the one high-density city area (downtown) – but that doesn’t mean C-Train trips are always beginning by walking, cycling or transit. Nearly every single C-Train station is complemented with a large, land-intensive park and ride – ensuring that parking can be reduced in the space-limited downtown core.
Outside of this pattern, it’s a toss-up. There are few dense nodes on the LRT lines, and little variety in commuting patterns. Coherent transit usage demands good transit development and a robust city-wide transit network, but the bus system has obviously has not grown to be robust enough to prevent the need for so many huge park-and-rides. And without a robust city-wide network, it also becomes difficult to compete against commutes to areas where jobs are concentrated over lower densities (like industrial parks).
As a result, of the $6.14 billion the City of Calgary is earmarking for transportation investments in the next 10 years, 63% of that money will be going to roads – far outpacing investments in transit, walking and cycling. Clearly, the road network has remained to be of far greater economic importance than the C-Train light rail system in the city of Calgary.
If reduction in road expansion is supposed to be one of the major goals of rapid transit, then the C-Train network may as well be a colossal failure.
All the Light Rail advocates I have heard from seem to have this fundamental value that it is Light Rail’s viability in Metro Vancouver and especially South of the Fraser is proven by the various examples around the world. Because we currently do not have such a system here, Light Rail has become a sensational topic among transit discussion circles.
Many of these advocates think it’s as simple of a matter as “If it works for ________, it will work for Surrey.”
As shown by the Calgary example, that is clearly not the case.
