JOINT BAR Meaning and
Definition
-
A joint bar is a device used in the construction and maintenance of railways. It is specifically designed to connect two sections of rail together, creating a continuous track line.
Typically made of steel, a joint bar is a flat and elongated piece of metal with holes on each end. These holes are used for fastening the joint bar to the rail ends, typically secured by bolts or other specially designed fasteners. The joint bar is usually installed at the point where two rail sections meet or align with each other.
The primary purpose of a joint bar is to provide stability and strength to the rail joint, ensuring a secure and smooth passage for trains. It helps to maintain the continuity of the track, preventing any misalignment or separation between adjacent rails. Additionally, the joint bar also assists in distributing the weight and impact forces evenly across the rail joint, reducing the risk of damage or failure.
Joint bars are often used in conjunction with other components such as rail clips, fish plates, and rail pads to create a robust and reliable rail infrastructure. They are essential in ensuring the safe and efficient operation of trains, as well as facilitating the movement of goods and passengers across the railway network.

Etymology of JOINT BAR
The word "joint bar" has its roots in the combination of two separate words.
The term "joint" comes from the Old French word "joint", which means "to join or connect". It can also be traced back to the Latin word "iunctus", with the same meaning.
The word "bar" originated from the Old English word "bær", which referred to a piece of material used to block the entrance to a space. Over time, the term took on various meanings, including a barrier or obstruction as well as a place or establishment where alcoholic beverages are served.
When we combine these two words, "joint" and "bar", we get "joint bar". In this context, a "joint bar" refers to a location where two separate bars share a common dividing wall, counter, or entrance.
