Toronto Crosstown LRT | ?m | ?s | Metrolinx | Arcadis

[crs1026]

There were cars slipping and sliding all over this week - one incursion onto an LRT track really isn't big news. If we are going to design barriers around vehicles taking random unintended paths, I would say it should be done on a prioritised "realistic potential for harm" basis - which to me says we should put barriers at every intersection and bus stop (where people may be gathered) before we worry about lrt's on an open stretch.

Is there a reason we don’t have barriers for the majority of the above-ground alignment excluding the intersections? Perhaps some sort of metal fencing as opposed to concrete jersey barriers (given experience with Union Station, once those go in they’ll never leave because the cost of replacing them will keep
escalating year over year.)

Isn't there fencing just a little further down the road in the direction the picture was taken?

There's gotta be some reason why it wasn't installed on the entire stretch up to the DVP.

There is a height difference of greater than a curb in some places, thus the fencing is needed as prevention to a fall from the ROW.

Also, that fencing is not nearly strong enough to stop a vehicle. There has been a lot of it replaced already due to impacts with cars and trucks.

True but I think the fence in that street view around swift dr. exists because of the road curvature. The small fence will at least stop most vehicles if they are slightly veering out of their lane.

It seems like the fence is there for maintenance workers and emergency evacuation passengers to not fall onto the roadway if they had to walk beside the track.

Very rough notes/some paraphrasing from the Eglinton West Q and A where Crosstown progress was asked.

• Major construction done, small works tiles, water leaks, pipeline issues to resolve;
• System tests are critical. In December they were 15% complete and as of March they were 50% March complete;
• First big concern: software defects in trains and software progress. Not as fast in terms of progress. Last week, release 6 of software which addressed some of the issues; release 7 planned for June. Softare is the never centre for the keeping the trains on time and safely;
• 20 TTC trainers (I assume trained or to be trained?); there will then be 90 operators trained in in three groups;
• 41 occupancy certificates required, and 36 now awarded; Kennedy and Cedarvale the latest. Yonge-Eglinton the biggest. Nearly there. Some deficiencies to address; and
• Second biggest concern: construction certificates. Only 1/46 certificates done with the rest in progress.

Would construction and repairs ramp up next month when the weather is warmer?

• System tests are critical. In December they were 15% complete and as of March they were 50% March complete;

so by summers end it should be 100% complete then (35% in 3 months to 85% in June)

• First big concern: software defects in trains and software progress. Not as fast in terms of progress. Last week, release 6 of software which addressed some of the issues; release 7 planned for June. Softare is the nerve centre for the keeping the trains on time and safely

How many patches do they think theyll need?

• 41 occupancy certificates required, and 36 now awarded; Kennedy and Cedarvale the latest. Yonge-Eglinton the biggest. Nearly there. Some deficiencies to address;

progress looks good; hopefully they can divert more resources as stations are signed off

• Second biggest concern: construction certificates. Only 1/46 certificates done with the rest in progress.

wowsers! what is taking so long?! how is this different from occupancy certs?

In case someone wants to hear Phil say it himself lol

Media article noting the above.

‘The nerve centre’: Issues with Eglinton Crosstown LRT software persist - Toronto | Globalnews.ca

By June, software meant to run trains on the route will be in its seventh iteration. The head of Ontario's transit agency said the program will be the 'nerve centre' of the LRT.

[*]First big concern: software defects in trains and software progress. Not as fast in terms of progress. Last week, release 6 of software which addressed some of the issues; release 7 planned for June. Softare is the never centre for the keeping the trains on time and safely;

So there is still big concerns with the software, and they won't even bring in the next release for 3 months! And then they have to test it ... so can't begin a 3-month countdown for at least 7 months - probably more.

Sounds more like a 2025 opening, assuming there's no major construction deficiencies. They didn't say much about such deficiencies, in the bit I heard.

How can there be software defects, if we've been using the same cars on the downtown network for 10 years and ION for the last 5? What on earth are they doing?

The downtown streetcars aren't the same. Most significantly, it doesn't use ATC.

ION had ATC issues for a while, though most of the route they don't use it. Is it the same ATC system as Line 5?

 

[cplchanb]

I wonder if the 90 operators and the 20 trainers can be trained to operate together at the same time and then the 20 do additional instructor training? I have feeling this may be a big bottleneck at the home stretch, especially if version 7 of the software is unsuccessful

ION doesn't use ATC. ION uses ATP. Vehicles on ION are controlled by the operator at all times with the ATP providing a display with maximum permissive speed limit. It's a different setup to what is going to be used on the Crosstown. On Line 5, the trains are driven by the computer in the ATC section, much like on Line 1. this requires software with much deeper integration with the train systems than ATP would require, as ATP only requires the ability to activate train brakes for overspeed events.
