BART is the only transit system in North America that uses the Indian gauge. The wider gauge also contributes to the noise it generates and the wear on the track around turns.

Wear on the track: Presuming that the turns aren't too tight a radius (which may be larger for the larger gauge), and the superelevation is correct (which probably has to be larger for the larger gauge), why should wider track mean greater wear on curves?
