The set with 4527 and 7033, seen here on one westbound and one eastbound trip, is an incredibly rare 8-car set. You almost never see a train that long on the Main/Bergen line. It wasn't seen again after the eastbound clip, so maybe it was sent to a different line.
I have relative up in Ridgewood I recently visited and took the train from Hoboken and I enjoy coming up to Ridgewood such a beautiful town upper Bergen county...
