Canada Line | Completed

[officedweller]

Note that I don't think you can assume that the Canada Line will be travelling at maximum speed - at least not for the "initial" service plan.

Maybe they were being conservative with travel times and Richmond to Waterfront ends up being much faster.

Could you explain the numbers - they're not making any sense to me.

Thanks

edit: never mind, I found it.

My guess is that the maximum acceleration is limited by some standard or regulation. Each of these technologies are capable of much higher accelerations. There's not much difference between an induction motor and a linear induction motor, except that the stator (or rotor) is rolled out along the guideway. Actually, a regular induction motor is likely built to much tighter tolerances simply because it's a discrete device built in a more controlled environment.

For example, the new trolleys accelerate very quickly. The Berlin metro seemed very quick off the start too. Maybe the limit varies a bit from place to place.

I think the Berlin U-Bahn is an exception to every rule when it comes to its acceleration. I'm still shocked at how quickly trains get off the platform!

I think the biggest factor is adhesion. With Linear induction, the magnets pull the train, so adhesion is not a problem. On the Canada Line, the trains will rely on the grip the wheels have on the rail for acceleration, so it will be less efficient and starts will be slower on hills and in wet weather (the Canada Line trains will probably carry automatic sanding equipment, just like Edmonton and Calgary LRT).

Yep... for all intents and purposes, the skytrains wheels are constantly in neutral... they slow down by reversing the motors (and returning energy to the system) and only use their brakes when they're coming to a final stop.

i am really wondering if the sounds of the canada line is gonna be louder then skytrain from the outside

Accelerating, it's going to be no louder than a trolley bus or other traction based rail systems like in Tokyo, New York, Hong Kong, etc. It's quiet compared to LIM technology.

Braking, you might hear the the rails/wheels/brakes screeching but it's preventable through gradual braking and good maintenace.

Anyone hear the Canada Line trains through Richmond yet?

Jared posted a few videos a while back. Search for them on youtube.

I did a few times when I was driving on No.3 Rd. Even though I didn't really pay too much attention to it, but I think the loudness is similar to MKI/II at least from outside.

From Jim's pics at the Canada Line website:

[Whalleyboy]

the video dont help i'm curious of the outside noise not in the train

and Henry if you can try and pay more attention and find out next time your by them it would be greatly appreciated

[Whalleyboy]

also well i'm thinking of it i've noticed the front thing where it says where its heading(cant think right now of name lol) isnt gonna be all that good on this line with how the front basicly sits out view when in the stations it basicly useless seeming or is that just my view on it
i mean sure you can probably get a quick view of it but thats it

[nname]

Interesting that they have the "Oakridge-41st" programmed onto the front display, which isn't a terminal for the actual operation. I wonder how would they program a longer station name such as "Broadway-City Hall" or "Vancouver City Centre"

[Whalleyboy]

it will probably be like the buses
just flash things like vancouver then city centre
its that or sliding it across it

That's not really a big deal. Even if the stations were big enough for an overlap who is going to walk all the way to the front of the train just to see the display sign when there are display signs hanging all over the platform stating the same information. The front cab display on this and all metro systems is for exactly what you said, getting a quick view of it as it enters the station... it should really be all you need.

[deasine]

Exactly. But then again, I wish they had side ones too >___>

[Metro-One]

This picture here actually shows how much larger these cars are than the Mark 2 and especially the Mark 1 cars. It looks massive compared to the cars on the road too. I think they wil look like great trains with the C-cars in the middle (I do wish the line were opening with the C-cars already in place).

^ pictures are actually deceiving....the Canada Line train is 5-metres longer than a two-car Mark II, and it's also taller given the moving parts underneath.
