I traveled in SL between Kopargaon and HWH when the train used to be late due to Maoist fear(World's largest democracy scared of Maoists. Lol). Maybe in 2010,2011 or 2012. Cant remember the exact year. Worst train regarding cleanliness. Worst gutka spitting and non toilet flushing crowd. Nightmare of a journey.
I remember travelling in sleeper in july 2012 from pune to kharagpur. At that time it was good and clean. But as it passed Nagpur, from chattisgarh till tatanagar, it was heavily crowded due to WL passengers, hawkers and general ticket holders. That was a nightmare and from that day onwards i always prefer this train's a.c class.
