In the US, 200 car trains are common, and much longer ones have sometimes been used. Depends on weight on driving wheels, gearing on power axles and engine power, also required speed. and weight of freight cars. At low speed, some locomotives could pull 100-freight cars that are lightly loaded.

How do freight trains pull so many cars?
TLDR Locomotives are able to pull heavy loads by gradually adding weight and overcoming static friction with the help of draft gears, low rolling friction, and powerful traction motors.
