Don't forget: brake pads.

The various facets of all transportation industries probably have as much or more asbestos grinding into the air with particulate matter from vehicular brake systems on trains and automobiles, and to a lesser extent aviation.

The soot in the NYC subway is probably ripe with asbestos. Every time I smell that acrid ceramic smell of new brakes on a subway car, I figure I'm catching a whiff of asbestos, and it's a smell I encounter more than talc.

I only know the smell for what it is from changing brake pads on my car a few times, years ago.
