A 46,513 kg train collides with a 2,623 kg car. According to Newton's third law, if the train hit the car with 31 kilo-Newtons of force
The question has insufficient information. F=ma. You have given only m.
The two sitting still on the track next to each other exert no force on each other. Both moving at the same speed in the same direction will give the same answer. Even if they collide, you need to know the acceleration (what change in speed over what time period) before you can estimate the force involved.
