He's A Really Useful Engine

He's a Really Useful Engine, you know
All the other engines they'll tell you so
He huffs and puffs and whistles...
...Rushing to and fro
He's the Really Useful Engine we adore!
He's a Really Useful Engine, you know
'Cause The Fat Controller, he told him so
Now he's got a branch line...
...To call his very own
He's the 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!
