Confederation Line (Stage 1) | In Service 1.0

I live right next to Walkley Station, and I hear the buses on the SE Transiteay way more than the Trillium Line. Having said that the "clack-clack, clack-clack" of the trains going through ellwood diamond can carry a surprising distance into the southern end of the Ellwood neighborhood, along kitchener

I've heard it as far as Grasshopper Hill Park in Alta Vista. Definitely audible in Herongate.

That said, the Confederation Line doesn't have any diamonds like that (yeah, there are the diamond crossovers but those are all low speed).

I hear that as well, from my house in Blossom Park.

Unless it's an old picture, Rideau still looks far behind.

That was my first thought too... but other than removing the temporary fences and ropes, what looks left to do?

Some of the white panels over the vaulted walls, the yellow tactile strips along the platforms (could be hidden by canopy structure or optical illusion due to lighting), I feel like something should be hiding the structure holding up the ceiling on the sides, painting the gypsum board under the concourse. Could be more I we can't see or haven't noticed.

It's no Komsomolskaya but I think Rideau ended up pretty nice looking. Just a few cosmetic things left (and the tactile strip as you mentioned) but pretty close to go live ready. Unfortunately, we did not have the benefits of a communist slave labour force.

Originally I thought Rideau was going to be the nicest, but I really think Parliament is going to be the star

Good Day.

Rideau - OK, so, like, what's with the signage every second panel of the centerline fence/barrier :

" Danger. Do Not Cross Tracks. High Voltage. "

What high voltage...... that's part of the safety of our system - the tracks are no / lo voltage (signalling backup fixed-block occupancy detection).

or is it just hyperbole to help keep the sheep in line ?

????? Opinions ?????

The tracks are the return feed for the power and thus should be near ground potential and thus safe (like the neutral wire in your household wiring). In a ground fault situation, they could have a high potential difference though. To be absolutely sure they would need to tie the rails to ground and maybe they aren’t (possibly for signalling reasons?).

Yep - the rails are grounded - intentionally and otherwise, by the inherent nature of where they are and how they are laid. Even the provision for fixed-block occupancy detection (the operational backup for CBTC) takes this into consideration, and is inherent in the design of the system. Tracks get grounded because they are on the ground. So.... no / lo voltage. Even a GFCI situation is designed for - the high voltage is drained off asap, and the power supply is cut as soon as the drain is detected.
The only risk is from third-rail power systems, like Montreal Metro, in which the third rail is highly insulated from the ground at every fix and mount. And it costs a lot in both installation and maintenance to keep it so. That is why OCS is considerably cheaper and easier, by comparison.

EnJoy!

It's just signage pollution. They have them all along the exterior fencing as well. And to think the decision to go with low floor was all based on the possibility the trains might run along the street. There must be a lot of electrocuted people in Toronto crossing the streetcar tracks

[J.OT13]

In defense of Ottawa, Vancouver has that too. Obviously not the same type of system (low-floor with overhead wires vs high-floor with third rail), but it could be argued that with Vancouver's system, it's more obvious you can't cross, so why the signs? In both cases, it's probably protection from litigation.

Edmonton (high-floor, overhead wires) has "no smoking" and "stay off tracks".

Seems pretty standard on most systems.

And Rideau again for comparison,

There is a difference between touching the ground and being grounded. Concrete is not a good conductor so to be considered "grounded" the rails would have to be connected to a nearby grounding rod buried in wet earth at regular intervals. Not easy in a tunnel.

I agree the risk is significantly higher with third rail systems. The rails will be safe >99% of the time, but that isn't good enough for safety regulators. They want a fail safe system.

Tracks the run along or cross streets would be required to have extra safety measures to ensure that the tracks are safe even in a fault condition. Since we aren't expecting people to be walking on the tracks, there is no need for those safety measures here.

Meanwhile in Edmonton:

https://www-cbc-ca.cdn.ampproject.org/c/s/www.cbc.ca/amp/1.5090426

"The company responsible for the Metro Line LRT's problem-riddled signalling system says the City of Edmonton has terminated its $55-million contract as of April 4.

Thales says its employees were escorted from the worksite last week."

I don't expect Edmonton's problems to have any bearing our system, but due to proximity of events I wonder if people will start chattering that we too use a Thales system, of a similar type to Edmonton.

[J.OT13]

I'm not expecting any issues of that magnitude in Ottawa. Ours is a fully grade separated system that is better suited to this type of technology. It's also a brand new system and doesn't have to work in unison with a system from the late 70s. This might come up in Ottawa media, but they're no evidence of any major problems with our system thus far.

Now for Edmonton, if they plan on ripping out the Thales system and starting from scratch, won't they have to shut down the line for at least a few months? If they have another contractor in the wings, this is a good time with school year nearly over and the Oilers out of the playoffs.

[J.OT13]

Listened to the City of Edmonton press conference. It seems they won't have to shut down the Metro Line and have hired Alstom to implement a fixed-block system similar to the Capital Line. Considering the nature of the Metro Line, this should have been done to begin with.

It seems like really they had no choice at this point. It's been years trying to get that to work.

I am worried though that people will make a false connection between their troubles and our system.

When will Confederation Line be open to the public?
