Dang, that's amazing!! You'd have to model that in Z-scale to get the same effect, on a very large layout!!
We have actually pulled couplers out of the socket on Z Scale 100+ car trains before. At the 2011 NTS we had 26 scale miles of Z Scale track on our multi-club Z-Bend Track layout, and a train of over 100 cars had about 70 cars behind the front loco set, and actually pulled the coupler out of one of my woodchip gondolas. We had to change the way we place helper locos to no more than 50 cars between helpers so we don't pull the couplers out of the socket!
