On my way to work today, I was a little surprised when I saw a 
approach and the side sign said 'TO DYRE AV' rather than 'TO EASTCHESTR-DYRE AV'. As it turned out, from Flatbush to President Street, the announcement goes 'This is a Manhattan-bound train' and only at Franklin Avenue it says 'This is a Manhattan-bound express train'. The rest of the stops in Brooklyn omit the 'express' part.
Same thing in Manhattan. Bowling Green to Fulton Street had the usual Bronx-bound announcement, minus the express part.
It's also worth nothing that I encountered a 
that said 'TO BKLYN BRDG'. Plus, I saw a 
that said 'TO WAKEFLD-241'.
And lastly, the I took back to Brooklyn only mentioned the express part on the Eastern Parkway express line.
One more thing to note, the sets that were updated (most of them weren't) had a glitch when announcing the transfers. It would do the glitch where it would play the conductor ding, followed by the doors closing ding-dong.
Anyone else encounter this or have more info?
