The Forgotten Hero Little Engine

This little engine spotted a danger sign ahead in the mountains and immediately blew its whistle, raising the alarm. The driver sensed something was wrong and quickly added fuel, regaining its strength. The little engine rushed forward toward the mountain. It seemed like nothing could stop it now. Just then a turtle appeared on the tracks. But the little engine break in time, saving everyone. When they reached the station, the owner told the driver that a new, more powerful engine had arrived and decided to retire the little engine. Even though the driver didn't want this, he had no choice but to accept it. The little engine was sold to a dark coal mine. There, it was forced to haul heavy loads day and night. Meanwhile, the big engine became everyone's favorite with its strength and speed. It crossed mountains with ease, opened new routes, and carried countless passengers and cargo into the city. Over time, everyone forgot about the little engine. Newspapers and media even declared the big engine the city's hero. The little engine quietly watched it all. It began to feel like there was no place left for it in the world. One day, while the big engine was crossing a bridge, the structure suddenly collapsed, leaving it hanging in mid-air. Below was a deep abyss. One small mistake, and both the engine and its passengers would fall. The little engine saw this. The supervisor tried to stop it, but it refused to listen. Breaking free from its chains, it rushed to help. Even when the supervisor fired at it, the little engine didn't stop. It began pulling the big engine. The big engine was extremely heavy, and its driver was trapped inside. The little engine was about to give out. At that moment, the big engine's driver managed to pour fuel into the little engine's tank. At the very last second, just as the bridge was about to completely collapse, the little engine used every ounce of its strength and saved the big engine, along with everyone on board. But the cost of that sacrifice was heavy. The little engine broke apart, turning into a pile of scrap metal. The driver refused to lose his friend. He gathered everyone together, and they rebuilt the little engine piece by piece. When it finally ran again, everyone called it the hero engine. And once more, it returned to its place working side by side with its driver.
