I was a passenger by SL of 16176 Karaikal (KIK)-Chennai Egmore Express on 16 Nov, 2013. I noted that the coaches weren't swept, though KIK was the point of origin for the train, and the train was available for about 8 hours in the station. The toilets were also stinking as they were not cleaned. I don't know if this is the case daily, or my day it was so.
The railways charge us for all these amenities.
