PA system in train bogies

Two recent incidents experienced in the train travel in the state have prompted me to write this , even though the suggestion was made by me about 20 years back too.

On 4th aug I was travelling from trivandrum to cherthala by Trivandrum lokamanyatilak express. While we were ready to get down at cherthala station, as the train was nearing the station, it abruptly stopped just outside the platform and for about half an hour there was no sign of the train moving . Finally, we walked through five bogies and got down from the train at the railway crossing on the road south of station. Even when we were leaving after having lunch at a nearby hotel , after about an hour , the train  was still stationery at the same place, without the passengers having any idea about what was happening! In the evening on the same day, I got an SMS from railways informing that the same train had been terminated at Shoranur railway station due to heavy rains in the northern part.

As per newspaper reports , the rail traffic on the Ernakulam Alappuzha sector was adversely affected on 7th august due to tree fall on the rails and many trains had to be diverted via Kottayam. In the evening same day,  tree fell on maveli express leaving Trivandrum,  again disrupting rail traffic for many hours.

My point is, in such eventualities of train being detained/terminated/diverted , at present there is no mechanism to keep the passengers inside the train informed about the position leaving them high and dry. This is all the more problem for long distance passengers . To alleviate such difficulties I had suggested installation of public address systems in all bogies through which the engine driver or the guard could apprise the passengers if any delay for more than 10 or 15 minutes was expected . This would be a big relief for the passengers inside the train, i believe .  

I have once again sent this suggestion to the railway minister too and hope it will be considered favourably.
