The answer is in the page itself "The High-Level Safety Review Committee at Mumbai on 12-13 January 2012 at the Western Railway HQ was skeptical of ACD effectiveness. They unanimously chose to develop TCAS as an open architecture system without charging royalties unlike the ACD which is proprietary" And this is in works, from last 8 years | ||

doesnt matter.. applies more to Railways - there is no way, a large scale tech will be imported from other countries to just plug&use.. its not just cost effective, its prudent to use our own tech.. its also the reason, thr is always a debate to allow PRIVATE players on railways.. dont think that will happen as well.. anytime soon.. brahma satyam jagan-mithyä jivo brahmaiva näparah | ||

you mean ACD ? https://en.wikipedia.org/wiki/Anti-collision_device Anti-collision device Indian Railways have successfully piloted ACDs in the northeast frontier railway, covering 1,736 kilometres (1,079 mi) of its broad gauge route. They are now installing the ACDs on 760 kilometres (470 mi) of the Konkan Railway. The on-board train protection device, the first device designed by Konkan Railway with their technical partner Kernex Microsystems (I) Ltd, was installed throughout the Indian Railway network. "A new ACD Version-II, now called the Train Collision Avoidance System (TCAS), is under development by The Research Designs and Standards Organisation (RDSO). Unlike ACD, which is more of a distributed system which acts independently, the TCAS will be more of a centralized system where TCAS controls communication between trains and with trains with the TDMA protocol. The TCAS under development is meant to be a vital safety system. TCAS has a deep coupling with the railway signalling system so ACD systems do not depend on the railway signalling system."
Agree with you.May be indigenous' systems are cost effective compared to other available commercial systems. | ||

Yes,it is important for national security ,defense or for long term strategies ..it is good to develop indigenous technology and be self reliant But not railways ..they are commercial enterprises ..I don't know how managing level crossing or tracking trains movement effects national security..than imported telecom equipment that are relaying every cellphone call! | ||

i am not supporting the slack.. definitely slack is involved.. but more intrusive PSUs - there are very strict instructions to use only indigenous tech.. that includes lots of institutions like IIT, ISRO, HAL, .. railways lo slack undi ofc.. brahma satyam jagan-mithyä jivo brahmaiva näparah | ||

in the past Indian Railways also worked on developing (wasted money !) anti collision system https://www.financialexpress.com/india-news/trials-on-indige nous-anti-collision-technology-to-avert-rail-mishaps/370516/ ..still not deployed as it failed miserably I don't understand why we need to waste money trying to build 'indigenous' systems for commercial usages,when there are readily available efficient commercial systems ? It does not makes any sense..either technically or business wise Then India has to develop it's own CT Scan machines,Own aircrafts,own cellphone technology etc | ||

Yes I understood and here as per this news article ISRO developed GAGAN geo-positioning system that not only track train movements, but use this satellite-based system to check accidents at unmanned railway crossings. | ||

Firstly pls don't get confused with satellites and IRNSS or technical jargon even my car uses satellite navigation system comprising of 24 active satellites to guide route or track the location of vehicle IRNSS is Indian version of GPS ..,but IRNSS has only 6 satellites and accuracy is less commercial GPS is available to use from decades and railways would have started using from much earlier.. | ||

It will take time to link 10800 locomotives to ISRO satellites and they started working on this from last year Jan, | ||

They are using GPS. Indian Railways is using IRNSS ధూమకేతుర్గణాధ్యక్షహ ఫాలచంద్రోగజాననహ | ||

Is it really a rocket science ? Why it took so late ? RTC buses have GPS trackers and scheduling system from many years Even all rental cars have GPS trackers ! | ||

https://www.timesnownews.com/business-economy/industry/artic le/irctc-good-news-for-train-passengers-indian-railways-link s-locomotives-via-isro-satellites/348583 Good news for train passengers! Indian Railways links locomotives via ISRO satellites New Delhi: Good news for train passengers: the Indian Railways has linked its locomotives via ISRO satellites, making it easy to track trains and automatically feed the control charts about the train's arrival and departure, officials said. "A new beginning has been made in the new year: the train movement information is acquired and fed to the control charts using ISRO (Indian Space Research Organisation) satellite-based real-time train information system (RTIS) automatically," a senior railway ministry official told IANS. The official said that the system was implemented on January 8, on some of the mail or express trains on the Shri Mata Vaishno Devi Katra-Bandra Terminus, New Delhi-Patna, New Delhi-Amritsar and Delhi-Jammu routes. The official said the new system will help railways to modernise its control room, railway network for more efficient train movement across its network. The official said, "The move is aimed at further improving the accuracy of train-running information." Explaining how the new system works, the official said the RTIS device installed in the locomotive detects position and speed of the train using GAGAN geo-positioning system, developed by ISRO. "Based on this information and application logic, the device sends the train movement updates (arrival/departure/run through/unscheduled stoppages and mid-section updates) to a central location server in the CRIS data centre using S-band Mobile Satellite Service (MSS) of ISRO," he said. After processing in the CLS, this information is relayed to the Control Office Application (COA) system for automatic plotting of control charts without any manual intervention in the divisions," he said. The official said that earlier, the train running status used to be updated manually. "Before this technique was developed by the CRIS (Centre for Railway Information System) in collaboration with ISRO, the divisional controls set up for the purpose of train movement control were dependent on the information relayed by the station master to the station controller and the data was fed in the control chart by the section controller manually," he said. He said the COA is being already integrated with National Train Enquiry System (NTES). The official said the railways is also working with the ISRO to use its satellite-based system to check accidents at unmanned railway crossings and track train movements. Earlier while Working on a pilot project with ISRO, the railways installed space agency-developed integrated circuit (IC) chips on some train locomotives. "The Indian Regional Navigation Satellite System was used to warn road users of approaching trains through hooters installed at unmanned road crossings," the official said, adding that now the railways has also eliminated all the unmanned level crossing except one in Uttar Pradesh due to some local issues. |
