The great train snaked on through the dark, pounding out the miles through the empty plains and mingy hamlets of Georgia, the 'Peach State', the angry moan of its four-toned wind-horn soughing over the wide savannah and the long shaft of its single searchlight ripping the black calico of the night.
Where it comes from
