Why do trains have 3 locomotives?
The Short Answer. Trains have multiple engines to provide more power to pull the train. Each locomotive has a certain amount of pulling power (called “tractive effort”), which is related to how many horsepower the diesel engine in the locomotive has.
How does a train pull so many cars?
The train has a big engine in it. This engine makes the wheels turn to pull the rest of the cars. If we consider the train and wheels as the system, the force that changes its momentum is the static friction force between the wheels and the rail.
