How does Kavach work on Railway Systems?

The Traffic collision avoidance system (TCAS), with the help of equipment on board the locomotive and transmission towers at stations connected with Radio Frequency Identification (RFID) tags, helps in two-way communication between the station master and loco-pilot to convey any emergency message.

in advance without visual sighting, and the permissible speeds to be maintained.
If a red signal is jumped and two trains come face to face on the same line, the technology automatically takes over and applies sudden brakes.
Additionally, the hooter activates by itself when approaching a level crossing which serves as a big boon to loco-pilots during fog conditions when visibility is low.

It is a loco cabin and RFID based system. It can be applied in Frieghts also.

I agree.

According to some recent discussions in the forum, it is a temporary step, until the long awaited , so called "kavach installation" on 160 kmph routes. track-fitted RFID tags shall be used for communicating an upcoming signal in and level crossing in driver cabin. Also ,There have been recent instances of Gatimaan running way over PSR at places.

However, I still regard it as a retrograde step. Despite field trials between 2015-2017 and live demonstration in 2022 , It seems kavach installation has not been done on routes with trains running at 160kmph . None of the recent rail accidents (except in Balasore one) were trains running at 110 or 130 kmph , let alone 160 .

Some issues have been plaguing IR for long - Lack of proper fencing, lack of adequate security system, lack of R&D in improvement of rail security, huge vacancies - They are trying to brush these under the carpet by reducing speed in name of risk mitigation .

Quoting from the above article -"we were not able to run trains at 160 kmph because the track was not safe to operate at that speed. Unless the organisation is culturally ready to maintain high-tech signalling equipment, high-speed tracks and rolling stock, no matter what trains we buy or make, we will be constrained to run at lower speed only."

It is more of a coverup exercise - issues like lack of adequate high-tech signalling equipment, high-speed tracks , maintainance issues, long working hours of LPs and ALPs , snail's pace progress on installation of anti collision systems - they are trying to divert attention from these issues by reducing speed in name of "risk mitigation and security measures". God forbid , but accidents can happen, and, have happened in the past at even lower speeds .

Mission Raftaar down the drain, it seems - probably "yatri suraksha" was...
