R160 - Manhattan Bound F via D [West End - 4 ave Local] announcements

Caught this F train going over the west end (D line) on 2/26/12 after a Rail condition occurred at church avenue on the F line . In result F trains ran via the D from Coney island to west 4th street and select F trains ran as a shuttle between Ditmas avenue and Coney island. I was suprised when this train was also diverted onto the local tracks after 36 instead of running express to Atlantic avenue.
