Hindi rail teck , absolute block working system | automatic block working system | 18 differences between them | Good evening friends, I am Deepak Kumar , welcome to my channel " HINDI RAIL TECK " Following topic covered in this video. absolute block working system in railway, automatic block working system in railway, system of working in railway, differences between automatic and absolute block working system, What is the Automatic Block system?) In Automatic Block Signalling (ABS) the signals are automated and operate in conjunction with track circuiting or other means of detecting the presence of a train in a block section. [2/05] As of March 2003, IR had 3,606 kms of track under the ABS system. When a train enters a block section, the stop signal protecting that block changes automatically to on or the Stop aspect. As the train moves ahead out of that block and into the next block, the signal aspect changes automatically to Caution. In multiple-aspect signalling, when the train is 2 blocks ahead the aspect then changes to Attention, and then to Proceed when the train has passed 3 blocks ahead. In 3-aspect signalling, the aspect changes to Proceed when the train is 2 block sections ahead. In automatic block territory 2-aspect signalling is not used. Each change of a signal to a less restrictive indication requires the train to have moved an adequate distance in advance of the signal. Absolute Block System of train working: ‘Absolute block’ refers to a system where the track is considered to consist of a series of sections, such that when one train is occupying a section of track (the block section), no other train is allowed to enter that section. This is the most widely used system for ordinary train routes.A station or signal box controls a block section in one direction (from its rear), and no train may enter that block in that direction without permission from that signal box (the station or signal box is said to accept or receive the train). When a train has been accepted, no other trains can be accepted on that block section until it has left that block section. Obviously, the two signal boxes at either end of the block section have to tightly coordinate their actions, especially in the case of block sections that allow bidirectional movement on a single line. The permission to enter the block may be in the form of a physical token carried by the train crew while the train is in the block, or may be implicit in the aspects of signals governing access to the block.The block section is usually taken to be the section of track from the most advanced signal controlled by the station in the rear (usually the starter or advanced starter signal), and the rearmost signal controlled by the station ahead (usually the home or outer home signal). #automatic_block_working_system #absolute_block_working_system Indian railway establishment-    • Indian railway establishment   Block instrument in Indian railway-    • Block instrument in Indian railway   Shorts video-    • Shorts video   Objective questions & answers for railway departmental examinations like station master, goods guard,TC,CC, RAILWAY GROUP B POST ETC -    • Objective questions & answers for railway ...   Railway latest update-    • Railway latest update   Indian railway job-    • Indian railway job   Authorities, standard forms & abnormal working in Indian railway.-    • Authorities, standard forms & abnormal wor...   SPECIFIC WORD USED IN INDIAN RAILWAY. -    • SPECIFIC WORD USED IN INDIAN RAILWAY   INDIAN RAILWAY SIGNALLING SYSTEM.-    • INDIAN RAILWAY SIGNALLING SYSTEM   Railway stations and system of working. -    • Railway stations and system of working   Indian railway train accident & there analysis-    • Indian railway train accident & there anal...   Amazing sights of Indian railway-    • Amazing sights of indian railway   Follow on Blogger- http://hindirailteck.blogspot.com Follow on Facebook-   / hindi.rail.teck   Follow on Instagram-   / hindi.rail.teck   Subscribe my channel-    / hindirailteck   #indianrailway#hindirailteck#sigals#tracks#hindi #differences_between_absolute_block_and_automatic_block_working_system #system_of_working #indianrailwaysignallingsystem
