Comment on at least no more trolley problems

If he pushes off the train, starts from Vo=Vtrain, he simply has to push off less than he would if he were standing still to get to the kid, since Vkid_intercept would be quite a bit greater than 0 anyway.

He would also decelerate (and then accelerate) during the kid intercept, which being ‘super’, I would expect him to be able to do, as he can perceive things faster as well.

Snap the neck? Just support the neck. Just put the kid on his whole torso so the kid’s body experiences the acceleration as a monolith as if on a rocket seat.

Him starting off at the velocity of the train is the problem. It's not as simple as "Superman just goes a little faster," momentum has to be conserved. To launch himself forward he has to launch the train backward and the train likely doesn't survive that. Continuing to push the train was still likely the best option Superman had in this situation.

  Is he canonically heavier than the train?
  
  He can ‘run faster than light’, or at least, it’s safe to assume he is faster than all human technologies of mobility in the context. All he has to do is accelerate to a speed, taking into account the distance required to decelerate to a non lethal speed to intercept the kid.
  
  It’s basically this - the deceleration required to reduce the speed to one that is either a full stop or at least a non lethal one at the point of impact can, by definition, instead be imparted to the kid. A hypothetical person in the first engine that supes is acting on is experiencing the same deceleration as would be required to accelerated the kid during intercept.
  
  The kid intercept is simply a more efficient way to address the situation, albeit a less dramatic one.

    You're ignoring the part where I said this seems to be a memory of an earlier point in comic history for Superman we're seeing. This version of Superman is almost certainly nowhere near that fast.
    
    He also doesn't need to weigh more than the train for the train itself to not be able to withstand the force of him pushing off.
