I was certainly surprised by how sharp some of the curves are in
Toronto. Here's a pic of the tightest I saw - and the flanges certainly
screamed!

Toronto cars are single ended so there is a loop at each terminus. This
one, at Union Station is underground and is VERY sharp.

Note the rail visible outside the line of the car.

My guess is that these curves may well have an impact on Toroto's choice
of new cars.
