The closures were because of snow blocking (insulating) the third rail. I rode the subway north of Bloor today and in the a lot of the open cut sections the third rail is still almost totally buried, with just enough metal exposed for the contact shoe to pick up power. And some of the trains had...

I would guess the TTC can't turn the power off at Union without turning it off at King. I know when Andy Byford was in charge they modified the power distribution system so power could be turned off on the bridge without turning off the power at Broadview. I'm not sure if they did any other...

The half height doors would (I assume) not have the same fire code implications as full height doors. Seeing how they are pretty much the standard for brownfield installations in Japan I suspect they have other advantages that are not captured in the TTC's evaluation matrix. This could...

I wonder if the easiest fix at this point is to just replace these trains with a better design. While scrapping essentially brand new trains would be scandalous, if the design is this deeply flawed with no fix seemingly coming it might be easiest option and certainly cheaper than doing any major...

10-15 minutes from Mount Dennis to Cedervale and 40-45 minutes from there to Kennedy would fit. This is also assuming the first eastbound train turns at Kennedy to become the first westbound.

That sign also reveals the round trip time between Cedervale and Kennedy is about 90 minutes including a layover at Kennedy. So probably around 40 minutes one way.

Trains can operate in emergency mode without supervision of the signal system. The question is whether it is a good idea, the TTC using emergency mode to deal with problems with the CBTC system would be what they call a "normalization of deviance".

Coteau only has a platform on the south track. So train 35 may have had to wait for train 62 to pass to cross to the south track to serve Coteau.

The 30 minute service is showing in the GTFS feed starting on January 5.

Sheppard was way less complicated. Eglinton among other things has been a systems integration nightmare. Some of this is due to newer code requirements, but for instance maybe in hindsight it should have been built with a more conventional lineside signal system rather than CBTC. Eglinton is...

One thing to keep in mind is that HSR doesn't really need massive terminal stations. Probably 4 tracks would be enough.

For Finch even without signal priority just having trains run at the speed limit of the road and not cross intersections at 25 km/h would be a big improvement, and even more so if the signals can be set up to give trains green waves.

My guess is the 30 Lambton which used to have hourly service in the evening.

Going east from Yonge this usually happens at Broadview, for headway control at the interlocking signal, Coxwell for crew changes, and Kennedy when trains are approaching the station more frequently then they are dispatched in the opposite direction. So the following trains get stuck at red...

The inverters in this case were I'm pretty sure for the lighting and other auxiliary power, not the actual propulsion system which was DC chopper control from Brush Traction. Overhauling this (especially replacing DC chopper with AC inverter) would have been a much more substantial job. So I...
