Toronto Eglinton Line 5 | ?m | ?s | Metrolinx | Arcadis

confirmed

This word is doing alot of heavy lifting.

What is obviously the case now is that we have either been mislead OR the issue was not fully understood before the minister issued a statement. Eitherway, we should know better than to take the ministers, PMs, or metrolinxs words as fact. Actions over words and all.

Remember, transit signal issues and crosstown are synonymous and so to hear that the signal system is once again causing problems is not a suprise on to itself.

 

[Thaboss]

I wonder what all the train testing currently going on is for if there is a signal issue holding everything back?
Perhaps they want to make sure the operators don't get rusty.....

Or maybe RSD is still technically on even if at a reduced capacity, since you only need 20 days of no bad things happening.

Trains have been operating for multiple years now. RSD or not, that was always going to happen, for training and testing purposes.

what on earth happened that this issue would suddenly pop up after months of normal testing? did they stumble on a bug? besides it was already confirmed to be mainly driver error. considering the huge implications politically and financially, why are they striving for NASA levels of perfection?

When trains are moving in the yard there are no human drivers on them the driver is the signalling system. The human error mentioned was either the human behind the desk in the control centre that queued up the route orders or the human who misconfigured the yard signal blocks and switch interlockings.

I don't take the "human error" label too literally, other than indicating a political desire to assure the public that somebody's neck is getting wrung.

When I read @smallspy 's description of constrained speed and headways, my mind can't help but run to "block length" and "stopping distance" parameters, which then leads my mind to run to "design attributes of the supposedly proven and vanilla signalling software" and "things about the design attributes of the software that may not be compatible with the as-built track and platform attributes and as-input data tables, in delivering to the desired performance envelope of this system".

That would shift the human error away from operations and closer to design and engineering.

But that may be letting my mind run away with things.

why are they trying to reinvent the wheel.... is the yard that vast with so many hundreds of trams that they need to waste resources on inventing a solution in search of a problem? just have drivers do the operating. problem solved!

Meh, I don't actually mind that they're trying something new. The future is founded on the wheel reinventions of today

Just sucks that this keeps happening to the Eglinton LRT. We're about to enter year 15 of the project - you'd think they were building some super railway with the amount of time that has been taken

This isn’t about reinventing the wheel, and this certainly isn’t the first time yard movements have been automated in the world. This is about automating the trains through the daily maintenance tasks like train washing, cleaning, sand filling and fleet rotation. All things that need to be done in a short time frame and can’t be done by TTC operators because the TTC isn’t responsible for the maintenance.

bet they spent 5X the costs building said system than it would cost to have personnel on site for 10 years.

Opening by the Dec 21 board period seems hopeless then; no way this opens by EOY. Absolutely pathetic job all around

Depends which year.

However, this is what the testing is for. Can you imagine the furor if this happened a month after opening?

. considering the huge implications politically and financially, why are they striving for NASA levels of perfection?

I hope they strive for far better than NASA levels of perfection. With the space shuttle, they only had a 98.5% mission survival rate - with 1.5% of the missions ending in the explosion of a space shuttle with all crew killed.

And the numbers for a successful automated Mars landing are even worse.

Isn't the LRT yard a fully automated full size train set?

ill take those odds just open it

Forreal, Line 1 never runs on time even with ATO. Just compare your trip times with what the trip time is supposed to take on Transit or Google Maps. A Line 5 beset by delays is better than no Line 5.

Makes me think of this XKCD:

Yes, but I think this is the one you were looking for.

More than 30 days after entering final tests, Eglinton Crosstown LRT still being assessed - Toronto | Globalnews.ca

On Oct. 7, provincial transit agency Metrolinx announced the Crosstown had started revenue service demonstration, a key 30-day testing process.
