Railroad spike, also known as cut spike, is usually used in railway to fasten the steel rails tightly on the sleepers. The railroad spike is invented by Robert Livingston Stevens in early 19th century. At that time, English mainline use railways used heavy and expensive cast iron chairs to fasten T-shaped rails, while Stevens come with up an idea to add a supporting base to T rail that is fixed with a simple spike. In 1982, this spike has become the most common rail fastening in North America.
At the early times, dog spike is commonly used when wooden sleepers is paved on the railway. However, with the concrete sleepers popularized, screw spike is more and more widely used. Railroad spike is mainly classified into two types: dog spike, screw spike.
A dog spike equal to a cut spike in function, it has a square section in horizontal direction with a pointed penetrating head, which is similar to a dog's lugs. This is why it is called dog spike.
