    Default Six-car Trains

    Can the Century Park leg of the LRT scale up for more capacity?

    • Will any platform accomodate a train consisting of six cars?
      .
    • Can the existing LRT bridge accomodate two trains of six cars passing in opposite directions?
      .
    • Is a scenario feasible where six-car trains stop at platforms shorter than the train?

    I watch packed trains go past a path I walk along and wonder what the future holds as the City moves forward with its insideous plans for permanent major disruptions to traffic flow along the southside corridor of 109th street.

    Plans are in the works for 104th, 103rd and 99th streets, too.

    While adding more trains of three-five cars are an obvious first response to be seized upon by the bureaucrats who make such decisions, the cost of this bandaid lies in FURTHER crippling east-west bound commuter traffic stuck waiting for the crossing arms to lift at every one of the level crossing said bureaucrats saw fit to approve along the Century Park line.

    Extending an existing five-car train would add 20% passenger capacity while having little additional impact on east-west traffic delays.

    Once inside a train, passengers are free to move from car to car. On the face of it, it isn't necessary for every car to open onto a platform. Is it unreasonable for passengers to exercise some foresight with respect to positioning themselves at an appropriate door prior to arrival at their platform of choice in exchange for more opportunities to have a seat along their journey?

    Our LRT does not support movement between cars; each is seperate unit, with no gateway between them. You can move between cars a station, if you're quick enough, but that wouldn't work if your car is not adjacent to a platform.

    Not a bad idea assuming the track can handle 6 car lengths, but a few issues with the train/platform interaction:

    1. Saftey risk unless cars are modified to lock doors that are not adjacent to a platform. You can potentially custom build/modify some "end cars" that have one door disabled, but you lose flexibility in putting the cars together.
    2. Passenger at wrong exit door might not be able to relocate in time to beat the rush of passengers entering the train.
    3. Adds a very significant learning curve to using the train, could be a huge issue for tourists and occasional users.
    4. Proper signage and awareness campaign could help, but won't be 100% effective.

    Have you ever been on our LRT cars??! What are you talking about, "passengers are free to move from car to car"?

    All the underground platforms max out at 5 car train lengths; you're not going to start excavating to expand them.

    It would be easier to increase frequency back to 5 minutes than to add an extra car, which would mean adding length to each station along the route.

    increasing frequency by a minute will make a tons of difference. Too bad the NAIT LRT line fluck up screwed up the frequency on the existing line.

    I'm going to assume that the closest he's been to riding Edmonton's LRT is seeing a TV show or movie of the subway in New York.

    Let's wait and see what happens once the SE Valley Line is open. Some of the traffic will be diverted.

    Increasing the frequency, which means buying more and putting more 5-car train sets into operation, works.

    But I have already heard the Mayor start talking about limited-stop commuter rail:

    I realize. The OP on the other hand doesn't seem to realize that our LRT cars are self-contained. I goofed and quoted the wrong person in my original post, though.

    I think we are a long, long ways away from commuter rail as mentioned in that article, though. Let's finish all the legs of our current LRT before worrying about that. Not to mention finishing Terwillegar Drive as a true freeway and re-configuring the Terwillegar/Whitemud interchange.

    Thank you for the correction.

    It has been maybe seven years since I last commuted on the train. Also, long before the extension to Century Park went into service, I swung from straps weekdays to/from University Stn before descending into the depths to ride to Corona, Bay and Central.

    In my mind's eye, I could picture the disc in the floor and the bellow sections separating cars - forgetting that this is just the pivot point between the fr/rr halves of one car, not the joint between separate cars.

    Nothing like failing to do the research and giving C2E vultures something to sink their beaks into, eh?

    Are you implying that people travel west from Millwoods to Century Park and ride the LRT north from there? (Century Park because I'm not sure there is suitable parking further north at Southgate. Quite a horde of cars congregate in neighborhoods surrounding South Campus, but MW to SC by car seems a painful journey.)

    Had not considered that. If so, I suppose that SEVL will divert those people (or at least their progeny.)

    Yes.

    At least from the western portion of MW. Relatively quick bus connections make it easy. I presume at least some of them will divert eastward once the SE Valley Line is open.

    Very few riders go to CP from MWTC to take the LRT. It makes no sense doing so as the ETA of that ride depending on route is anywhere from 25-45minutes and with two of the routes snaking through such places as Ellerslie and South Common prior to taking riders to the promised CP named destination of the routes.

    Its deplorable connections, so inefficient, and would be the slowest way to get somewhere possible. Connections to Southgate via #6 are no better and especially during rush hour.

    The CP traffic by and large is not coming from Millwoods, Meadows.

    Ummmmmm, what? Very MANY riders go to CP from MWTC to take the LRT. The 23 goes straight down 23 ave to Century Park, and takes about 15-20 minutes. Most Uni students living in Mill woods, and the meadows take this route.

    ONLY people going to U of A would take that route to CP. There would be no other reason to take it. If going DT for instance simply take the 15 which gets there in around 40 minutes, no need of a walk from transit at CP to LRT at CP.

    Also, indicating how little this is used the bus only runs every half hour, and is not clearly marked as the route states WEM, not CP. The two other busses that run to CP from MWTC are also milk runs that go to Ellerslie and/or South Common. Those busses are run every 15mins and offer extremely poor time efficiency to CP. If you can catch the 23, which is rare (weird scheduling also results in it not being timed well with feeder routes and I rarely if ever see it at the MWTC) So that what you don't mention is you end waiting longer to take the 23, which then takes 20mins (rarely the 15 quoted on the schedule) then the walk to LRT platform, then the wait for the LRT. Then the walk up the cavernous U of A LRT station. Its by no means a great route.

    Just checked on google maps and the quickest runtime quoted to U of A from MWTC is to take the 70, then the 4.

    Taking the LRT can seem quicker but when factoring in all the walking and time that takes and that the LRT station at U of A is very inconveniently located way underground its not so great.
