It was probably 664, the only PM train to skip Huntington. From what I remember this train used to run with 7 cars and 2 engines, but it was cut to 6 cars and 1 engine after 2010 cuts. I haven't ridden it in a while, but 6 cars usually did the trick. Once 662 is put back to Hunterspoint instead of Huntington 664 should be less crowded
