brooklyn subway waterfall

While I was taking this shot the subway conductor yell that "they all ready know about the problem". So I looked back at him and he yelled it again. I said thanks and kept taking the photo, and that really bothered him. He proceeded to inform Naomi(who was also taking a photo with her new camera phone) and I that "they also aren't sure where the water is coming from". Even as the train was pulling away he felt the need to stick his head out the window and scream it ONE more time. Shouldn't he be worried about driving the train?
