As the train has its PM by South Central Railways, the cleanliness of the whole train is without any question and the sleeper coach never spills out with UR or WL Pax even from HWH. The problem that you'll face in this train is that there will be too many eunuchs and beggars all the way round and they generally roam around the sleeper coaches. If you get up from HWH then youll be amazed a bit because everyone goes to the upper berth and just doze off! :P The pantry service of the train is excellent, provides tea with Marie/digestive biscuit for Rs 10 and breakfast items include Standard breakfast meal (Bread-cutlet/Bread-omelette), Upma vada and also chowmein. For railfanning, The SL berth of the Sleeper is the best according to me.
