What is railway signaling


Railway signaling refers to the system of communication and control devices used to manage train movements and ensure safety on railways. The primary goal of railway signaling is to prevent train collisions, derailments, and other accidents by controlling train speeds and movements.


Railway signaling typically includes a combination of fixed signals (such as lights or flags) and movable signals (such as switch points) that are controlled by a central control system. The signals indicate to train operators when it is safe to proceed, when to slow down or stop, and when to change tracks.


The signaling system may also include track circuits, which detect the presence of trains on the tracks, and interlocking devices, which ensure that switches and signals are properly aligned before a train can proceed.


Railway signaling is a critical component of railroad operations, and its design and implementation must adhere to strict safety standards and regulations.

3)What is Approach locking & Back locking with conditions ?

  3)What is Approach locking & Back locking with conditions ? Ans) * ROUTE HOLDING IS DONE BY APPROACH AND BACK LOCKING. Approach locking: It is an electrical locking which doesn’t allow us to alter the route when train entering into the station. For providing approach locking , a track circuit for a length of 1.2kms. Need to be provided. Provision of such a long track circuit for the purpose of approach locking is a costly proposition. Therefore, the approach locking is provided without the approach locking becoming effective the moment the signal is cleared irrespective of the position of the train in the approach.Such an approach locking is known as “Dead approach locking”. In other words, once the signal is „OFF it gets approach locked and the route can be released B ack/Route locking: It is an electrical locking ,whenever train passes the signal and it effective until the train occupies & clear the all tracks in route including last point section.The route...
