Does this mean they've done away with the rubber tyred trains?

No. I believe http://world.nycsubway.org/perl/show?15541 shows
one of the new trains on the right; if you brighten the image, you
can clearly see the rubber.

But aren't those on line 6, not line 1? I remember when it was
converted to rubber-tyre working (line 6, I mean), during my years
there.
