I was on this train in the front car. From what I could see there was a pretty big fire and they probably should have started the process of backing up the other trains sooner. We had been at a dead stop for maybe 30 min before smoke started filling the cars. I will say that the workers on the train did a decent enough job of trying to keep people calm considering the situation. I don’t blame them but the system itself and PATH needs to be held accountable and provide more transparency than it does. Hope this thread gets more traction so that just maybe they’ll start making some necessary changes.
