What is wooden part of a railroad track?

The wooden part of a railroad track is known as the railway sleeper or railroad tie. It is a rectangular piece of wood, typically made of hardwood such as oak, teak, or jarrah, that supports and anchors the rails.

The use of wooden railway sleepers dates back to the 1830s when railways first started to be developed. They were preferred over stone blocks because they were easier to manufacture, transport, and install.

The size and shape of railway sleepers vary depending on the specific requirements of the track. They are usually 8-9 feet long, 9 inches wide, and 7 inches thick. They are treated with preservatives such as creosote to prevent rot, insect infestation, and weathering.

In recent years, concrete and steel sleepers have become more common because of their longer lifespan and higher durability. However, wooden railway sleepers are still widely used in many countries, especially in areas where raw materials are abundant or as short-term replacements during maintenance works.
