If the train is at the front, it pulls. If it is at the back, it pushes. Typically trains pull there cargo
Push and pull forces are used when there is a need to move objects or to change their position. Pushing is exerting force away from the body, while pulling is exerting force towards the body. These forces are common in everyday activities such as opening doors, lifting weights, and pushing a shopping cart.
Actually, its not. It depends on the direction of the force vector use to push or pull. If the two directions are equal, and the position of the force vectors are consistent with each other, then the amount of force to push would be the same as the amount of force to pull. You are probably realizing by now that when you pull an object, there is a tendency to lift it up from the surface, reducing friction, while when you push an object, the tendency is to push it down on the surface, increasing friction. This is why you have to be very careful and consistent in how you measure things.
Push on a wrench when loosening a fastener as this adds force to break it free. Pull on a wrench when tightening a fastener to apply force in the correct direction. Remember to use the correct technique to avoid injury.
Demographers use the push and pull theory to explain migration patterns by identifying factors that either push people out of one place (push factors) or pull them into another (pull factors). By understanding these factors, demographers can analyze why people choose to migrate and predict future population movements.
To move an object using force, you need to exert a push or a pull on the object. This force can be applied through direct contact or through mechanisms like levers or pulleys. The magnitude and direction of the force applied determine how the object moves.
we use force
That means that you use a force to push or pull something.
Force
You can push or pull in the same direction

i think it means to push or pull
push-pull tape rule
i think it makes no difference because locomotives use electric motors on the drive train

We use a pull.
No, you push the clutch all the way in to disengage the gear you are using from the drive train, and then you engage the next gear you want to use and re-engage that gear to the drive train.
