[Verse 1]
Once upon a time there was an engineer
Drove a locomotive both far and near
Accompanied by a monkey that sit on a stool
Watching everything that the engineer moved
One day the engineer wanted a bite to eat
Left the monkey sitting on the driver's seat
Monkey pulled the throttle, locomotive jumped the gun
And made ninety miles an hour on the mainline run

[Chorus]
Well, the big locomotive, and it's just in time
The big locomotive coming, coming down the line
Big locomotive number ninety-nine
Left the engineer with a worried mind

[Verse 2]
The engineer began to call a dispatcher on the phone
Tell him all about a locomotive was gone
Get on the wire, start dispatching them right
Cause the monkey got the main line sewed up tight
Switch operator got the message on time
The northbound limited on the same mainline
Open the switch, gonna let him in the hole
Cause the monkey got the locomotive under control
[Chorus]
Well, the big locomotive, and it's just in time
The big locomotive coming, coming down the line
Big locomotive number ninety-nine
Left the engineer with a worried mind

[Outro]
Big locomotive, big locomotive
Oh, the big locomotive coming, coming down the line
Big locomotive number ninety-nine
Left the engineer with a worried mind
Left the engineer with a worried mind
Left the engineer with a worried mind
