What makes an engine happy?
What makes an engine sad?
It all depends what's happened
And that type of day you've had
What makes an engine happy
Won't make an engine sad?
So many things can make your day
A good one or a bad

Chuffing children to the sea
Will make an engine smile
Or racing through the countryside
For mile on mile on mile
Just being really useful
Will make an engine's day
Or going somewhere different
Making new friends on the way

What makes an engine happy?
What makes an engine sad?
It all depends what's happened
And that type of day you've had
What makes an engine happy
Won't make an engine sad?
So many things can make your day
A good one or a bad
Running out of water
Yes, it makes an engine sad
Breaking down or being late
Makes an engine feel so bad
Getting stuck up Gordon's Hill
Won't please Sir Topham Hatt
But don't despair 'cause everyone
Has days can go like that

What makes an engine happy?
What makes an engine sad?
It all depends what's happened
And the type of day you've had
What makes an engine happy
Won't make an engine sad?
So many things can make your day
A good one or a bad

(Instrumental break)

What makes an engine happy?
What makes an engine sad?
It all depends what's happened
And that type of day you've had
What makes an engine happy
Won't make an engine sad?
So many things can make your day
A good one or a bad
