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

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.

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

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.

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.

As the earlier incident occurred during the unscored phase of testing, the timeline for RSD did not ‘restart’ to day 1 but rather resumed as unscored testing once the trains were on the line again,” a spokesperson told Global News.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.
“Should an issue occur during the scored phase, we would restart the specific week of scored testing but would not need to re-do the unscored portion.” The agency would not tell Global News how many days were left, but said the light rail route had now entered the scored testing phase.
20205 maybe still in play? Also no mention of that bedding in period hmmmm...
Edit: I was being sarcastic here. I know the 2025 dreams are probbaly dead. Metrolinx needs to be transparent about delays like the rem in montreal and the o train in ottawa have been recently. It serves no one other than the ford to pretend that everything is alright.
