Indian Railways — SMS in case of train delay

Address:	Mumbai City, Maharashtra, 400066
Website:	Irctc

We are ostressfu and waiting for same train at vasai road since last 5 hr. And still no confirmations that how much more delay is train..
There no announcement also there.
In such a delay case at least railway should send SMS for the delay. Like flights. That the only thing I can expect from Indian rail. So that in such big delay case a person can wait at home and leave according to train time.

This is very economical solution if airlines can do it then why can't Indian rail?
