View of the horseshoe bend from the air

Horseshoe Curve is a 3,485-foot (1,062 m), triple-tracked railroad curve on the Norfolk Southern Railway's Pittsburgh Line in Logan Township, Blair County, in the U.S. state of Pennsylvania. It is close to 1,300 feet (400 m) in diameter and has a grade of almost two percent. As a train travels west from Altoona, it ascends almost 60 feet (20 m) in the 0.66-mile (1.06 km) segment that makes up the curve and rotates 220 degrees. The curve was completed in 1854 by the Pennsylvania Railroad as a means of lessening the grade to the summit of the Allegheny Mountains by increasing the distance. It was built as alternative to the time-consuming Allegheny Portage Railroad, the only other method of traversing the mountains. It has formed an important part of the region's transportation infrastructure since its opening, and during World War II was targeted by Nazi Germany in 1942 as a part of Operation Pastorius. Horseshoe Curve was added to the National Register of Historic Places and designated a National Historic Landmark in 1966. It was also designated a National Historic Civil Engineering Landmark in 2004. (Full article...)

Rusty chain

Heavy rust on the links of a chain near the Golden Gate Bridge in San Francisco. It was continuously exposed to moisture and salt-laden spray, causing surface breakdown, cracking, and flaking of the metal. In colloquial usage, "rust" refers to red iron(III) oxide and is formed by the reaction of iron and oxygen in the presence of water.
