When it comes to communication, Indian Railways is still in the 18th century. Coming to the blocking of the train, I do not think it would have made much of a difference as the train would have got delayed once it crossed Roha. These rowdies consider themselves to be martyers. I won't be surprised if the 12431/32 Rajdhani and both Durontos now start halting at Chiplun, Kudal and Kankavli.
