It's "The Wheels of the Amusement Park Train Turn and Turn" by Baby Bus.

Lyrics:

The wheels of the small train turn and turn

The wheels of the small train turn and turn

Through the amusement park

The whistle of the small train beeps and beeps

The whistle of the small train beeps and beeps

Through the amusement park

The wheels of the small train turn and turn

. Turn off the switch

Turn off the door of the train

Go through the amusement park

The wheels of the train turn around

Turn around

Turn around

Go through the amusement park

Let's play again

Passengers of the train go up and down

Up and down

Up and down

. The wheels of the train turn and turn

through the amusement park
