Unfortunately, I was a Victim of this too. The Train I was on took 20 minutes to WTC waiting at each stop every 5-10 minutes starting at 23rd Street. Luckily it better by Canal St. I have to assume that was another train (Likely the C) before us because the train traffic announcement went off a few times. Things were slug on 8th Avenue (at least on my end). At least it ended when it did thankfully.
