When hooping up orders to a train, one must stand pretty close to the track - the poles aren't all that long. I never worried about suction, and after the engineer (or fireman) snatched the orders, you could hear the train pick up speed and the caboose was really travelling when it went by. Very hard to keep the hoop steady so the orders can be snatched. The conductor is supposed to have the orders but if it just an info type order, I would never give a 'wash-out' signal which would mean the train would have to back up.
There was a hill at one tower and a train could really pick up speed coming off that hill toward the tower. The senior men cautioned me to hold back the signal so the hogger would have to slow way down, then give him the signal, race down the steps, and hold up the hoop. Engine noise would drown out the epithets; never could hear what I was called.

I can believe that train suction is a myth, but I have experienced NASCAR suction. I used to work as a track worker for the SoCal region of the Sports Car Club of America, the California Sports Car Club. We routinely provided Flag and Communications workers for NASCAR when they raced at Riverside Raceway (of blessed memory).
I often got the job of manning, alone, the Black Board flag position. This was on the back straight just after the vehicle bridge. NASCAR used a track configuration that gave them a very long straight runup to the bridge. They reached well over 150 MPH as they blasted by into the Turn 9 sweeping hairpin.
My job was to be a repeater of the Black Flag information displayed at the Start/Finish line. I had a metal number board, magnetic numbers, one Black flag, and one "Meatball" flag. The "Meatball" was displayed if the black flag was for a mechanical reason; the plain black flag if the driver had been a bad boy.
So I listened for the command to fly the appropriate black flag, put the car number on the board, and showed the driver both as he screamed by at absolute top speed. I normally watched approaching cars standing back from the track so that only my head was visible to the driver. When I spotted the car I was to flag, I moved out to within 4 or 5 feet from the edge of the track and showed him the flag. The cars were usually right at my edge of the track to set up for Turn 9. The bow wave wasn't so bad but the suction behind the car was scary. I generally braced myself against being sucked toward the track and retreated as soon as possible. With cars running nose to tail at those speeds you really had to be careful.
I did this kind of thing for 30 years and it was hard work for no pay under sometimes harsh conditions, but it was the best seat in the house.

They used a dummy, albeit of an appropriate weight, so the whole bracing/overcompensating thing wasn't really addressed. Considering the force of the bow wave (measured at over 40 mph), it is entirely possible that a person could be knocked akilter, then lose their balance and fall into the train if it was long enough (or behind it if it wasn't). But it wouldn't be suction that did it.

NOTICE - If you haven't seen the show and don't want to know how it comes out - don't read this!
The pointy end did more "damage" than the blunt end of the train, but it was all the 'bow wave.' They didn't find any suction.... On the other hand, mom standing too close to the tracks with junior in his stroller when the train blows through at 79 mph will have her hands full, and baby may well get hurt.

Are those the ones with the shackles inside?
my guess is that that clip will wind up in a NM safety film or two - especially the stroller

It was originally scheduled to be shown about a month ago. I wonder why they pulled it at the last minute.
