Never Overlook a Little Engine is a song featured in Sodor's Legend of the Lost Treasure. It is sung by Rex, Bert, Mike and Thomas, portrayed by Tom Stourton, Keith Wickham and Tim Whitnall, respectively, as well as John Hasler (UK) and Joseph May (US). The song's lyrics were written by Andrew Brenner.


Rex and Bert: Never overlook a little engine
Little ones are really useful too
Mike: We've got trucks to pull
So make 'em extra full
I've never known a job that I couldn't do
Rex: (spoken) "With a little help from me maybe!"
All: Never overlook a little engine
We can take you where you want to go
We may have tiny track
But we'll get you there and back
And hold on to your hats
We don't go slow
Mike: (spoken) "Look out, Thomas!"
All: If you think that bigger's better
Then you're making a mistake
The ocean isn't wetter than a tiny little lake
A cherry might be tastier than a great big cake
And we can turn around in half the time those big guys take
Never overlook a little engine
We have set our sights upon the sky
You need a lot of puff
Bert: Being big is not enough
Mike: I've never known a job that I wouldn't try
Bert: (spoken) "Ha, ha! Me neither!"
Rex: (spoken) "Nor me!"
All: Never overlook a little engine
Bert: Like me
Mike: Like me
Rex: Like me
All with Thomas: Like us!
