Transit preparing to make tracks
City has added 15 kilometres of light rail in the last 30 years; it could lay eight times as much track in the next 30

After 30 years of slow growth, the LRT system is poised to undergo a dramatic expansion over the next few decades that could see tracks reach almost every corner of the city.
Under proposals set for a public hearing Tuesday, LRT cars would eventually travel to the southern boundary, Lewis Estates, St. Albert, the northeast Horse Hills area, Sherwood Park and Ellerslie, with an additional inner-city circuit tying downtown and Old Strathcona.
There might even be enough demand for a separate line to the northwest.
This ambitious program would involve a more than eight-fold increase in LRT track, to 128 kilometres from the existing 15 kilometres when Century Park opens in 2010.
While extensions to existing lines would use the current high-floor style of LRT trains, which passengers enter from raised platforms, planners suggest the new routes adopt low-floor technology accessible from simple curbside stops.
"In the long term, we're looking at bringing the city to a more urban centre ... (low-floor trains) can just fit in better to the community and the neighbourhood," transportation strategic planning general supervisor Rhonda Toohey says.
It's all part of the push to make Edmonton more compact, encouraging development along public transit corridors to help reduce sprawl that's bad for the environment and expensive to service.
But population concentrations will probably never be high enough to make LRT worthwhile in most of the capital region, including the Edmonton International Airport, with those areas better served by rapid bus or commuter rail.
Nothing will happen overnight. The only LRT extensions with routes in place are short hops to NAIT and Gorman -- the southeast and west approaches should be decided by the end of the year, while initial studies on a potential St. Albert alignment won't be finished until next spring.
The transportation master plan envisions the network being completed by 2041.
Long-range projections indicate that a century from now, the city core would see more than 120,000 daily riders, with fewer than 30,000 daily riders expected on outlying sections of the northwest, northeast, east, south and Old Strathcona lines.
Although the plan needs city council approval and plenty of money from other levels of government before it can be carried out, it's an important step in the LRT program, says Adam Laughlin, director of strategic transportation planning.
"It helps our specific corridor studies and provides them with the guidance needed on what the recommended route should be ... the technology helps in (deciding) the style of LRT system you want as well."

21st-century Streetcars
Planners foresee new stretches of the LRT network operating with low-key, low-floor vehicles that became popular in much of the world in the 1980s and resemble streetcars travelling along the road on a separate right-of-way.
Cheaper to build and maintain, stations can be built closer together in high-ridership areas. The trains integrate better with city surroundings and create less of a barrier to pedestrians.
They're part of a plan to move from our current suburban LRT system, featuring one to two kilometres between stations outside the city core, to an urban style in which the distance between stops is shorter to promote higher-density, transit-oriented development.
Infill stations might also be constructed on the existing system.
Low-Floor Trains
The new low-floor LRT trains wouldn't run on the existing lines or their extensions because they can't use the high-floor stations. Instead, they would follow a track separated from traffic, with priority signals so they wouldn't have to stop at intersections, similar to the current LRT.
Two frequently cited examples are in Portland, Ore., and Dublin, Ireland. Coun. Don Iveson says in a recent website posting (
www.doniveson.ca) that after riding the Dublin system last year, "I can attest to the lovely sense of appropriate scale as it worms its way through the city, stopping frequently enough to have an impact, but without disrupting the underlying feel of the city."
What's Next?
- Tuesday: Public hearing at the transportation and public works committee about the LRT network plan, including the technology that should be used, connections to the region and where new lines should enter downtown. This will allow for decisions to be made about the overall network before further analysis of specific west and southeast routes.
- June: City collects public feedback on the west and southeast route suggestions.
- September: Open houses on the recommendations.
- November: Public hearing, followed by council decision on which lines to adopt in these two areas.
Budget Costs
While there aren't any precise cost figures for building the proposed LRT network, the rough estimate is $9 billion in 2009 dollars.
The budget for the three-kilometre extension to NAIT from downtown is $825 million, although that might drop as construction costs come down.
Initial calculations last fall indicated the price of a line to Mill Woods at $1 billion to $2 billion, while the expansion to Heritage Valley from the still-uncompleted Century Park station is pegged at $640 million.
There are no promises for money to expand the system from the other levels of government, aside from $140 million recently announced to go from Clareview to Gorman. It has taken more than 30 years to build Edmonton's first 15 kilometres of track.
Capacity Crunch
It might take decades, but the downtown LRT tunnel will eventually reach its capacity handling the trains on the current system, the planned northwest extension and either increased service or one additional line.
While further studies are needed, one possible solution is a separate surface line with low-floor trains travelling through downtown and Old Strathcona. It would stop at some existing stations so passengers could transfer to the underground system.
LRT Expansion
Potential routes to the northwest and east are still in the future, but planners have already come up with possibilities for west-end and southeast lines.
There are five options for Mill Woods from downtown -- crossing the High Level Bridge and following the CP Rail right-of-way south, or reaching Bonnie Doon Mall via Whyte Avenue or the Low Level, James Macdonald or Dawson bridges, then south on 83th Street or 75th Street.
The suggested choices for LRT to Lewis Estates include lines from South Campus station along Fox Drive, Whitemud Drive and 87th Avenue, or heading west to 87th Avenue from Health Sciences station over a new bridge through the river valley.
Two other proposals would use 102nd Avenue and Stony Plain Road, or 107th Avenue, going south to meet 87th Avenue along 156th Street or 163rd Street.
