Drilling by tarriers (paddies) took place on the Union Pacific transcontinental route, but only a fragment of a song exists. The song "Drill, Ye Tarriers, Drill," may have originated with this railroad or with the Central Pacific, long before the 1888 sheet music was published.

Then drill, my paddies, drill,
Drill my heroes, drill,
Drill all day, no sugar in your tay,
Workin' on the U. P. Railway.

John P. Davis, 1894, The Union Pacific Railway, S. C. Griggs, Chicago. (Quoted from Norn Cohen, The Long Steel Rail.
