A legend from the past
Is born again at last
To rumble over mountains and the plains
From the golden age of steam
An engine seldom seen
By those who never lived in bygone days
Big Boy was her name
And went on to railroad fame
As the largest engine on the UP line
The last of all her class
She survives from out the past
To show the power of steam in modern time
Roll on Big Boy, Roll on Big Boy
Rumblin' across the northern plains
Roll on Big Boy, Roll on Big Boy
Climbing up the Wasatch Mountain Range
In 1959, They took her off the line
And wrote her off as progress for the times
No dry eye could be found
In jungles or in towns
Where once Big Boy had rolled when in her prime
From the junkyards of the past Forty fourteen is the last
To carry on the legacy of steam
At 4, 8, 8 and 4 And a part of railroad lore
She roars from out the past like some lost dream
Roll on Big Boy, Roll on Big Boy
Rumblin' across the northern plains
Roll on Big Boy, Roll on Big Boy
Climbing up the Wasatch Mountain Range
Roll on, Big Boy, Roll On
Roll on, Big Boy, Roll On
Spoken: Roll on, Big Boy, Roll On
Roll on
Roll on, Big Boy
