Once upon a time, there was a train named Choo-Choo Charlie. He loved to chug along the tracks.

Charlie had a big day ahead. He was taking people to the city for a special fair.

As Charlie left the station, he felt strange. 'Something is not right,' he thought.

He tried to push on, but soon he heard a clunk! His engine was in trouble.

Charlie was worried. 'Oh no! The people will miss the fair!' he said.

He called for help on his radio. 'Mayday! My engine is in trouble!'

Soon, a little repair car named Fix-It Freddie rushed to the rescue.

Freddie checked Charlie's engine. 'You've got a loose bolt. I’ll fix it!' he said.

The passengers looked on, hoping Freddie could fix the engine quickly.

With a twist and a turn, Freddie had Charlie's engine running smoothly.

Charlie thanked Freddie and chugged towards the city, right on time for the fair.

The passengers cheered, and Charlie felt proud. He had made it, thanks to teamwork!
