PR devises IT solution to avoid train accident at TAWC

ISLAMABAD: Pakistan Railways had devised IT solution for avoiding train accident at Level Crossings (TAWC) and Train Collision Avoiding System (TCAS).

This was disclosed in a briefing to Chairperson Ministry of Railways Parveen Agha by the PR officials on Train Approaching Warning System at Level Crossings (TAWC) and Train Collision Avoiding System (TCAS) here on Wednesday.

The purpose of the briefing was to find out IT and indigenous solutions for controlling the accidents.

The chairperson was informed that TAWC has been finalized and 5 prototypes will be installed new signaling system at busy crossing points till December.

The TAWC will consist of sensor on both sides of level crossing at the distance of almost 3 kms.

Sensors will detect the movement of train. There are dual sensors which will provide redundancy and compensation for variation in depth the officials said.

Sirens will also be installed to alert the pedestrians or vehicles.

The clearance to passerby will only be given after the train passed. But this system will not supersede the responsibility of locomotive drivers and gateman.

This system will provide audio visual warning signals to vehicles and pedestrian. There will be 7 inch high brightness display for driver’s information.

Video of crossing with reasonable resolution will also be provided to locomotive drivers when train is three km away.

The system should maintain alarm and video log in addition to event log for period of 15 days. The system should provide HD video in driver’s cabin system .The frequency will be 433 Mhz.

The official also briefed the chairperson about another system of TCAS.

This system will avoid the risk of collision of trains due to human error and equipment failure.

This system will act as a watch dog. In the system radars will be used in trains so that trains can identify each other.

It is a GPS based system, which will tell the drivers about the time, location, speed and course of travel of the approaching trains that can collide .

It will be fitted in locomotives and brake vans. As a result there will be long range wireless communication between units while there will be warning lights also.

Both these systems are evolving. For usage of these systems trainings will be given to drivers.

It was decided in the meeting that media will be engaged in order to give awareness to public about TAWC.
