Actually it's not that simple...many factors conspire for the best profile per demand, which vary radically. What is *generally* true is that flange wear is to be avoided if at all possible. But that doesn't negate the role of flanges in the least...even double flanged wheels are called for in some very demanding situations...(like roller coasters and mines)Take that gum out of your mouth. You might learn something today.
How do train, light rail, subway, streetcar wheels stay on their track? If you answer the "flange", that's only a safety device. It's the shape of the wheel surface itself.

Wheel geometry and flange

Most train wheels have a conical geometry, which is the primary means of keeping the train's motion aligned with the track.[1] Train wheels have a flange on one side to keep the wheels, and hence the train, running on the rails, when the limits of the geometry based alignment are reached, e.g. due to some emergency or defect. See Hunting oscillation. Some wheels have a cylindrical geometry, where flanges are essential to keep the train on the rail track.

All part of Metrolinx's Master Plan! /sIf VIA were adding a station there, then the Leslie stop would no longer be useless.

Dont worry, Del Duca surely wont miss on opportunity like this to keep us updated on what it is.Don't lose track of this event? Yea, whatever it is, it has something to do with tracks.
