[Chorus]
What makes an engine happy?
What makes an engine sad?
It all depends what happens
And that time of day you've had
What makes an engine happy?
Would make an engine sad?
So many things can make your day
A good one or a bad

[Verse 1]
Chuffing children to the sea will make an engine smile
Or racing through the countryside for mile on mile on mile
Chuffing really useful will make an engine's day
Or going somewhere different, making new friends on the way

[Chorus]
What makes an engine happy?
What makes an engine sad?
It all depends what happens
And that time of day you've had
What makes an engine happy?
Would make an engine sad?
So many things can make your day
A good one or a bad
[Verse 2]
Running out of water; yes, it makes an engine sad
Breaking down or being late makes an engine feel so bad
Getting stuck on Gordon's Hill won't please Sir Topham Hatt
But don't despair 'cause everyone has days can go like that

[Chorus]
What makes an engine happy?
What makes an engine sad?
It all depends what happens
And that time of day you've had
What makes an engine happy?
Would make an engine sad?
So many things can make your day
A good one or a bad

[Instrumental]

[Chorus]
What makes an engine happy?
What makes an engine sad?
It all depends what happens
And that time of day you've had
What makes an engine happy?
Would make an engine sad?
So many things can make your day
A good one or a bad!
