The Mysterious Track - S1.E5

Trumpee and Snaree set off to explore the world. They come across a long railway track. The two Meloditties don’t know what it is and think it's an enormous xylophone, but the Xilo brothers are sure they're wrong. After a while, they hear a whistle blow, then there's a rumbling sound, and a train arrives. The Meloditties then do the locomotion, led by Maestro Nomo, with appropriate music playing in the background.
