  The idea is he's straining so hard because he's trying to use the exact amount of force he needs to stop the train without harming anyone inside. Too much force on the train and everyone in the train gets injured or killed, too little and it doesn't stop in time to save the kid, and I believe in this one he didn't have the option of just grabbing the kid because he would have been hurt too badly from the sudden acceleration.

  If you've ever tried to assemble something where you've gotta snap together two pretty fragile pieces it's a similar idea. You absolutely can generate way more than the force needed to get the job done, the difficulty is in having the pieces survive the attempt.

  I can tell you I have experienced it with models and computer components and you'd absolutely think I was arm wrestling a God with how much I was straining trying to push those parts together without breaking them.

    But then isn’t he accelerating the people on the train just as much?

      Yes. In the opposite direction, gradually. It’s called deceleration. The mass of the train would spread the impact of Superman hitting and slowing it across the entire train, rather than the frame of a tiny human going from not very fast, to super man flying speed. At least that’s how I’m rationalizing it with rudimentary physics. I’m probably wrong.

      There’s a whole locomotive between them to dampen the impact.

      Same reason why modern cars are designed to crumple. It absorbs more of the impact before it reaches the people inside.

        So only the first ten or so cars will be scenes of unbelievable carnage. Meanwhile, he could have simply picked up the kid and cushioned him from the impact.
