Joe Halderman -- the man accused of trying to extort $2 million from David Letterman -- was spotted at a Connecticut train station this morning, allegedly heading to NYC.

The camera guy asks Halderman how he's doing -- we can't tell if he says "Hey," "Great" or something else.

FYI -- Halderman has pled not guilty to the felony charge of attempted grand larceny in the first degree.
