Here's a really useful engine you know
All the other engines you so
He huffs & puffs & whistles

Rushing to & fro
He's the really useful engine we adore
Here's a really useful engine you know
'Cause the fat controller he told him so

Now he's a branch line to call his very own
He's a really useful engine we adore
He's the one
He's the number one
Thomas the tank engine
He's the really useful engine we adore
