I feel like I just saw an ICE disappearance crew assemble on the 1 train? A bunch of middle-aged guys wearing similar logo-less ball caps got on and stood facing the doors, but each at a different door, acting like they weren't together, but clearly making little whistles and beeps into their logo-less jackets. They got off at 145 and one had his hands out wide, and another guy quietly said "137." They slowly all emerged and walked toward the exit, pretending to be separate.
