It had an EMD 567B 16-cylinder (engine), cylinder engine producing for its six traction motors. United States railroads bought 188 units. This was the first model in EMD's SD ''(Special Duty)'' series of locomotives, a lengthened B-B EMD GP7, GP7 with a C-C truck arrangement.

Fort Worth And Denver City, Diesel Electric Road Switcher No
A fortification (also called a fort, fortress, fastness, or stronghold) is a military construction designed for the defense of territories in warfare, and is used to establish rule in a region during peacetime. The term is derived from Latin ("strong") and ("to make"). From very early history to modern times, defensive walls have often been necessary for cities to survive in an ever-changing world of invasion and conquest. Some settlements in the Indus Valley Civilization were the first small cities to be fortified. In ancient Greece, large cyclopean stone walls fitted without mortar had been built in Mycenaean Greece, such as the ancient site of Mycenae. A Greek '' phrourion'' was a fortified collection of buildings used as a military garrison, and is the equivalent of the Roman castellum or fortress. These constructions mainly served the purpose of a watch tower, to guard certain roads, passes, and borders. Though smaller than a real fortress, they acted as a border gu ...
