The effect is much stronger when the moving train is in close proximity

Standing next to a fast train can be very dangerous as they can create a
suction effect that will pull you in. A conductor mistakenly put my
grandparents off on the wrong side of a train just as a streamliner
passed.
He grabbed the stationary train and his wife and it took all his
strength to
hold her. The railroad awarded them free travel on their trains for the
rest
of their lives. They never got on another train, free or not.
a quick demo of this phenomenon, a fun one too, can be done as so:
place to small boats (or floating objects) in a large bowl (or tub) of
water, get a water sprayer and squirt in the middle. one would think they
would float apart, but in fact, they come closer. regardless of depth of
bowl (so water doesnt "bounce" off the bottom and push them together. i
believe the higher flow caused by the squirter is akin to the bernoulli
affect. fun stuff :)
