Thomas Curtis Clarke,
The American Railway: Its Construction…
“ The world was born again with the building of the first locomotive and the laying of the first level iron roadway. The energies and activities, the powers and possibilities then developed have acted and reacted in every sphere of life—social, industrial, and political—until human progress, after smouldering like a spark for a thousand years, has burst into a conflagration which will soon leave small trace of the life and customs, or even the modes of thought, which our fathers knew. But, in it all, the railroad remains the most potent factor in every development. ”
