John Moody,  The Railroad Builders: A Chronicle of the Welding of the States

“ The story of the Baltimore and Ohio Railroad takes us back more than ninety years. When the scheme for the construction of a railroad from Baltimore to the waters of the Ohio River first began to take form, the United States had barely emerged from the Revolutionary period. Many of the famous men of that great day were still living. ”

“ The Baltimore and Ohio climbs the Alleghanies on inclines of 116 feet per mile. The Virginia Central Road crosses the Blue Ridge by grades of 250 and 295 feet per mile; and the ridge through which the Kingwood Tunnel is bored, upon the Baltimore and Ohio Railroad, was surmounted temporarily by grades of 500 feet per mile, up which each single car was drawn by a powerful locomotive.
Another element, of which American engineers have freely availed themselves, is curvature. More power is required to draw a train of cars around a curved track than upon a straight line.
