LIVE RAIL Meaning and
Definition
-
A live rail refers to an electrified rail line or track that carries a high voltage electrical current, typically used to power electric trains or trams. It is an essential component of railway systems that utilize electric propulsion. The term "live" indicates that the rail is actively conducting electricity and poses a potential danger to individuals or objects that come into contact with it.
Live rails are typically made of metal, such as copper or steel, and are installed parallel to the running tracks. The electrical current is supplied to the rail through an overhead wire, third rail, or other transmission system, which is connected to a power source. The current is then distributed to the trains or trams through a power pickup system, usually in the form of pantographs or sliding contacts.
Due to the high voltage present in live rails, strict safety measures are implemented to prevent accidental contact. Safety precautions include warning signs, barriers, and insulating covers to prevent unauthorized access to the rail. It is essential for rail workers and maintenance personnel to be well-trained in safety procedures when working near live rails, as any contact with the electrified rail can result in serious injury or even death.
In summary, a live rail is an electrified rail line or track that carries a high voltage electrical current, supplying power to electric trains or trams. It is a crucial component of electric railway systems and requires stringent safety measures to prevent accidental contact.

Etymology of LIVE RAIL
The term "live rail" is derived from the combination of two words: "live" and "rail".
1. Live: The word "live" is borrowed from the Old English word "līf", which means "life". It has been used to describe something that is active, functioning, or having an electric current flowing through it. In the context of electrical systems, "live" refers to a conductor or wire that carries an electric current.
2. Rail: The word "rail" comes from the Old French word "reille", which originally meant a bar or rod. It later became associated with the metal bars used as tracks for trains or trams.
When these two words are combined, "live rail" refers to a rail or conductor that carries an electric current. It is commonly used in the context of railway systems to refer to the electrified third rail or overhead wires that supply power to the trains.
