you don't need to disassemble the TBMs to go through the station boxes. All that is needed is a set of temporary guide rails installed through the station box to allow the TBM to move. The already excavated station boxes also allows for more thorough TBM maintenance and inspection.

the schedule is for the first train to start at 5:30 AM at the terminus stations not at the individual stations in between. Those stations have their own first and last train times. So while the schedule for Line 1 for example is for the first train to start at 5:30 at Finch, the first trains at...

could also have been a contact strip failure that caused a snag and pulled the line down with it.

So far it’s just moving the left turn phase to after the east-west straight phase (currently it seems to be programmed statically based on time of day). They can’t dynamic changes until they get their order of LIDAR detectors in and reprogram the controllers to use them. Once that occurs they...

There is the ability to manually activate the sander through a push button, but the control software also automatically activates it when it detects a spin-slide.

Could be Alstom techs testing the new update for the signalling software though they shouldn't be using in-service cars for that due to liability concerns. someone probably thought it was funny to toss something onto the overhead line. Easily removed with a hot stick.

The TTC order was an exercised option that existed in the initial order contract. Alstom still has a few contracts that have options left for the Flexities but other than those Alstom has no incentive to keep making the Flexity line in North America, even if it is proving to be superior.

Heating from train brakes, the AC, the compression of air as the trains move, the heat loss from when train doors open in the winter, and heat loss from various electrical systems on the train and radiant body heat from passengers will all warm up the tunnels. Most of that heat will be absorbed...

the tunnels themselves will warm up over time. The fact that they are cold now means they'll be a relief in the hot summer months. But the downside of them being so deep is that once they do warm up they'll hold that heat for a long time.

This is an accessibility feature. The beeps come from a small speaker above each door and are only active when that door is open, it's to aid those with vision impairments to find the exit.

Some of the lights were upgraded to truncate reds/extend greens recently with the more aggressive cycle rotation TSP coming in May (that part requires much more extensive changes to programming of the signal controllers). From my understanding the rest of the lights on the surface section will...

Was just a 2 minute delay because someone jammed the doors on a westbound train at O'Connor Station.

The doors are a fire code requirement nothing else.

as I just posted above, even if all the above you claim is true, that 31 minute difference in scheduled travel time is clearly going to make the LRT the better option to get across the city on Eglinton.

Considering only part of the journey is in the picture you posted, I decided to check myself. The LRT is scheduled to take 52 minutes. If you include the walk to the bus platforms at Mount Dennis (which on Google Maps isn't pathed properly to begin with) you get to that time. However, for most...

Probably related to deadhead times since the trains originate at Mount Dennis. Definitely something that will likely improve over time, especially if/when they start making use of the pocket tracks.

That was answered in the board meeting. The line was designed and built to support the TSP policy as it existed with the city at the time, which was for conditional priority only. As Mandeep Lali stated the policy hadn't been revised in many years and is now in the process of that revision (as...

the fire suppression sprinklers burst this morning I suspect due to the temperature shifts we've been experiencing lately. Mount Dennis Station does have a significant exposure to the outside air so I suspect Metrolinx and Crosslinx are now working on a permanent remedy to prevent this from...

They ARE using an off-the-shelf system Bombardier/Alstom Cityflo 650 CBTC. But like all modern signalling systems they have to be programmed bespoke.

and where that temporary tower was inside the building often becomes where the elevators go.
