    Exactly how fast do you think the people exit that portal? Train speed, less than train speed? What slows them down after they exit? If you blocked the stationary portal would you get hit by the people? If so, what force would cause that?

    The people may be stationary relative to the area outside the first portal, but they already have velocity relative to the world outside the exit even before they go through

    If there were no people on the track and you blocked the stationary portal, would you feel wind on your face?

      Zero fast. There is no energy being transferred to the people, they would plop out and push into each other as they are forced through.

      If you blocked the stationary portal then the portal moving would essentially just be a wall, no one would go though.

      This whole relative thing makes no sense, energy isn’t just created because it’s observed by someone else, the door is moving not the people so them sitting there won’t suddenly be catapulted going through a moving portal, where is that energy created?

      Your wind question is confusing.
