you push on the wall and the wall pushes back on you with opposite and equal force.
If the train is at the front, it pulls. If it is at the back, it pushes. Typically trains pull there cargo
inertia
static friction
Friction is a push force. When one object pushes one direction on an object the other object pushes the opposite direction. The harder an object is pushed against another the more friction there is.

It pushes back with an equal force (10 N). If it can not, then it falls over.

For every action there's an equal and opposite reaction. A clearer way of saying this may be: When you push on something it pushes back with a equal force. Think of pushing on a building. You apply a force on the building but it is pushing back with the same force, else it would move.
Well, if you don't push down the normal force will not push back.
