To get back on track, does anyone know how the AirTrain in New York handel in the winter? Seeing that it uses ICTS/ART technology.

I've been asking that question for years and have never received an answer from anyone - anti-ART crowd or otherwise.
As golodhendil said above the simple solution is to run trains overnight to prevent ice and snow buildup. In my opinion, paying a driver to do this might be worth it. In all but the most severe ice storms you would only need one train every 30 minutes, non?

The union may like that idea, but its kind of pointless if the trains are going to be (hopefully) automated.

I guess the key thing is that aside from cost and capacity concerns, which every line has, there isn't anything fundamentally wrong with the technology that can't be fixed through better design and operation.

And at the same time, there is nothing fundamentally better about this technology that the alternatives can't do.

Why not build subways for the SRT line? They could do better job.
The thing is we have to understand that Bombardier ART is different from UDTC ICTS that we've been using for 25 years.

That would mean the ART technology would work and the TTC or Metrolinx would start setting up more automated ART systems. The union wouldn't like that, would they?
Lets face it, if a LRT system could be automated they would have "problems" with snow.
Actually, Bombardier has tram automated systems (being tested by SEPTA in Philadelphia).
See this link for the information. When the LRV's run underground or in exclusive right-of-ways, they can be turned over for automated control. Whether or not the TTC will give control over to the computers in such a situation is another story.

The union would be up in arms over the idea of a automate LRT system. Same thing happen before the SRT went into service, the union was afraid that they where being replaced with computers.

That's the only alternative that makes any real sense, but this city is mostly allergic to sense.
299 bloor call control.

One very easy way to do this would be to have Metrolinx/GO Transit operate the line (and extend it along Eglinton to the airport). If it's not under TTC jurisdiction, the union is powerless.

That wouldn't be a bad idea. The TTC would have the Shepperd LRT services out that way and the SRT + Eglinton-Crosstown can be managed by Metrolinx.
One less expense to the TTC.

Even if you run ICTS overnight during a snowstorm, it will still fail. Here's why ...
When a train passes over the reaction rail, the heat causes any snow that has accumulated on it since the last train's pass to melt slightly. By the time the next train passes by, that water freezes on the rail. This process goes on and on and the result is a buildup of ice on the rail over time. Once it reaches a certain thickness, the party's over.

A convoy of covered wagons trundling down Brimley would be better than keeping the RT...it needs to be euthanized.
