Because of their location, platforms are now only allowed to be serviced by the regular corridor maintenance crews. So platform clearing efforts are not happening nearly as fast as they should. They are not supposed to push the snow onto the tracks as the operating crews are told to be cautious...

The TTC isn't the one that is saying that the trains can't operate at full speed in the subway tunnels. Neither is the City. Dan

The answer is none-of-the-above - Crosslinx, being the maintainer for the line, is behind it. They are worried about their staffing levels and the costs to maintain the equipment to the level that the TTC wants to operate to. Dan

You're comparing apples to oranges again. The Ontario Line's capacity specs are basically nonsensical. If you use the TTC's numbers - where they use the same metrics upon all of their fleets, and are based on over 100 years of actually providing service, rather than what looks pretty in a...

They do have special snow clearing rail equipment, and they're using them. But they also don't work particularly well on switches. Those need to be done with more specialized equipment - which the TTC doesn't own - or by hand. Dan

This is a temporary measure until the snow stops flying. It quite literally is a problem of aerodynamic forces affecting the loco intakes in push versus in pull. Dan

Only if you don't have to pay for it. Which, as a taxpayer, we all do. Dan

As a bit of an addendum to this.... Modern locos can develop in excess of 150,000 pounds of drawbar pull on the first knuckle - each. Type E knuckles are rated for a minimum of 350k pounds of force, type F for 400k pounds of force. (And of course they can sometimes handle more than this, but...

I believe that the overnight and weekend closures for the past couple of weeks have been due to work on the third track at Ossington. No - they, and specifically Drapeau, intentionally chose rubber tires in order to make the system more Parisien. That then forced the choice to keep the system...

They would often do the same on the rail side. And would take longer than promised to engineer it. But would then follow it up with an actual, functional product that did everything that it was supposed to, and sometimes and then some. Dan

I was referring to street-running vehicles in this context. Buses and streetcars. Of course a level loading vehicle like a subway is going to offer the best of all worlds. It's additional 2 feet of width over a streetcar also help in that regard. Dan

There is a known tendency for most types of third rail shoe to have issues when the snow gets higher than the rail itself. The cover helps protect the rail if the snow is falling straight, but with the blowing snow that was happening yesterday it becomes more problematic. In most circumstances...

That's incorrect. Low floor vehicles have faster boarding and alighting times, as the passengers don't need to climb stairs into the vehicle, which takes more time than walking on flat ground. Now, low floor vehicles do have a disadvantage with internal circulation, sure - but that only...

My understanding is that the three finalists were Bombardier, Stadler and the eventual winner, Siemens. Dan

The VLocity trainsets being built in Australia, which mechanically are almost identical to the various Voyager types operating in England and RegioSwingers operating in Germany and Croatia that Bombardier had been building since the late 1990s. Dan
