BLOCK SIGNALLING Meaning and
Definition
-
Block signalling is a system of controlling and managing railway traffic by dividing the tracks into distinct sections called blocks. It is used primarily to ensure safe and efficient movement of trains on a railway network. The aim of block signalling is to prevent collisions between trains by providing clear communication and guidance to train operators.
Each block is equipped with signals that indicate the status of the track section, such as whether it is clear or occupied by a train. The signals are usually placed at the entrance of each block, giving the train operator information about the presence of other trains ahead and whether it is safe to proceed.
Block signalling relies on a centralized control system, typically operated by a dispatcher or signalman, who monitors the status of each block and makes decisions based on the information received. The dispatcher coordinates the movement of trains, ensuring that only one train occupies a block at a time and preventing them from conflicting with each other.
This system is highly critical in ensuring safe train operations, preventing accidents, and maintaining efficient train schedules. It requires continuous monitoring, effective communication, and adherence to the signals by train operators. Block signalling has evolved over time, with advancements in technology enabling more automated and efficient processes.
Overall, block signalling plays a vital role in the safe and smooth functioning of railway networks by providing clear guidance, control, and preventing potential train collisions.

Etymology of BLOCK SIGNALLING
The term "block signaling" has its roots in the railway industry. The word "block" in this context refers to a section of railroad track between two consecutive signals, which is known as a "block section". The purpose of signaling in this system is to ensure that only one train occupies a block section at any given time, thus preventing collisions.
The etymology of "block signaling" can be traced back to the early 19th century when the railway industry was rapidly expanding. Prior to the development of block signaling systems, trains were operating on a timetable system, where they would proceed on a predetermined schedule without consideration of other trains on the same track.
However, as train traffic increased, this system became increasingly unsafe and led to numerous accidents. Thus, the need for a signaling system arose, which eventually resulted in the introduction of block signaling.
