Charles E. Burchfield, Journals, Volume 36, February 10, 1925

To concert by Cincinnati Orch. A. Honneger’s “Pacific 231” —
The power of a big locomotive expressed in music —
I still feel & hear the deep dull thuds of sound, suggesting terrific power —power that is at rest, but panting— At times the rhythmic exhaust snorts, growing more & more rapid—
Strange sounds of machinery —
The train rushing along at full speed at night — a terrific roar of sound, with violins making a shrill penetrating hissing sound as of escaping steam —
Charles E. Burchfield, February 10, 1925
