I heard the evening diesel whistle song
a mile of suburban streets away
distilled by distance in the quiet night
the roar beneath whistled air a harmony
denatured of its iron violence;
fundamental pulse of undercarriage
on the ballast, full-throttled baritone
of the engine, tenor groan of timbers
contralto clanging cars and ringing clear
soprano of the steel wheels shearing
at the rail’s endless edge, and knew
that I was home.
