Where are these locomotives now?

Dug up and displayed on railpictures.net is this photograph and a little tidbit stating it is now CSXT 6271. I decided to look for 6271 and found nothing. According to bullsheet the GP40-2 roster ends at 6249 and restarts at 6276. So what happened to CSXT 6250-6275?

Scroll down to the 6400s and 6900s.

I thought I double checked that. Oh well, thanks for catching my error.
