R32 B trains

I've seen some very recent photos of R32s on the B line. What meanth this? Anyone know?

It's good to see R32s return to the B line.

these are the R32s that once ran the N. Since the N is getting the R160s, them R32s are going to the (B) Line. I havent caught one yet, but i wanna see one of them in action on the Brighton line and the 6avenue express!
