As do all four lines of the Montreal metro.

Can't remember what the Paris metro is like but the Montreal one has a
bouncy unpleasent ride from what i remember. Not sure what the
advantage
the rubber tyres is (better on gradients?) but comfort doesnt' seem to
be one of them.

I don't remember the ride on the Montreal metro being bouncy or
unpleasant, though it's certainly different from the ride on
conventional steel-wheeled trains (you want bouncy and unpleasant, try
the Bury line on the Metrolink in Manchester).

As for the rubber tyres, I believe their advantages are partly about
negotiating gradients, and partly about negotiating curves without
slowing right down.
