Another old version, but it has only one verse. From The Santa Fe Magazine, Vol. 11, No. 3 (Chicago: Atchison, Topeka, and Santa Fe Railway Company, Feb. 1917), page 65:


THE BRAKEMAN
W. W. Adair

I am a jolly railroadman, and braking is my trade,
And I run upon the road both day and night,
Throwing switches, coupling cars, as along the road we go,
And I see that all the train is made up right.
Then here's luck to all the boys that work upon the cars.
May happiness and joy to them remain,
And the signals all be white when they come home at night
In the little red caboose behind the train.
