Condition of toilets in the coaches of IR is going from bad to worse. Recently travelled in the ACIII of Korba-VSKP Exp. and back, the toilets were stinking to the extent that I preferred not to use them. Thank God I don't have to perform very long journeys of more than 20 hrs, else travel by air is better even if it may cost double.
In many train toilets of ACII are also not upto the mark.
