Passenger Engine steamed off down the tracks. Tiny Train huffed and puffed to a stop. "Passenger Engine was going fast," she said, "but I could go fast, too. Small trains can do big things."
Tiny Train tooted her whistle and chugged off down the tracks. Soon she came to the zoo tunnel. A train car was stopped on the tracks. Baby Elephant sat inside the car. Railroad workers and zoo officials were looking at Baby Elephant and scratching their heads.
Tiny Train rolled over to the train car. "What's the matter?" she asked.
"I need to get into the zoo to be with my mother," said Baby Elephant. "But all the train engines are too big to go through such a small tunnel."
Tiny Train looked at the tunnel. "It's small," she said, "but so am i!"
Tiny Train backed up and hooked onto Baby Elephants train car. She puffed out steam, tooted her whistle, and chugged though the tunnel.
Baby Elephant was so happy she raised her trunk and let out a big tumpeting sound. Mama Elephant was also happy and trumpeted back.
