In the hustle and bustle of the train yard, there was a small, blue engine. Unlike the larger, more powerful engines, it was used for smaller tasks around the yard.

The big engines would often carry heavy loads over the mountain. They laughed at the Little Engine, doubting its ability to handle such a big task.

One day, a train full of toys and food for the children broke down. The Little Engine, despite the big engines' mockery, decided to help.

"I think I can, I think I can," the Little Engine chanted as it began its journey. Despite its wheels slipping, it did not give up.

The journey was difficult, the climb steep. But the Little Engine continued, repeating its mantra, "I think I can, I think I can."

The big engines watched in amazement as the Little Engine climbed higher and higher, inching closer to the top of the mountain.

With a final burst of energy, the Little Engine reached the peak. It looked down at the valley below, feeling a sense of accomplishment.

"I knew I could, I knew I could," the Little Engine sang triumphantly. It began its descent, carrying the load of toys and food.

As the Little Engine reached the town, it was greeted with cheers and laughter. The children were delighted to see their awaited toys and food.

The Little Engine felt a sense of joy and fulfillment. It had not only proved the big engines wrong but also brought happiness to the children.

Back at the train yard, the big engines were in awe. They had underestimated the Little Engine. From that day, they never mocked it again.

The Little Engine, with its determination and positive attitude, had overcome a great challenge. It taught everyone a valuable lesson: Believe in yourself, even when others doubt you.
