my sister in law could not get into the 3 tier ac coach as the coach was locked from inside and there was no tt there to help. train 6001 - came 1 hour late to katpadi station and hardly stopped for 45 seconds- her berth was in coach b1 - berth no 9; but she had to get into the 3rd last coach which was a general compartment without any light. it is irresponsible on the part of this train to come 1 hour late, then leave within 45 seconds, general compartment was dark looks unsafe, there was no tt to help, ac coach was locked from inside. she is travelling alone and this is the state of affairs. i strongly complain about this and request you to take care of her.
