12524 NDLS-NJP Express. Train was delayed from NDLS by 4-5 hours. Since, the UP train does not go to pit line for cleaning, all cleaning is supposed to be done on platform itself. Hence, one can guess what cleaning would have been done. Had a seat in first compartment in Sleeper class. The washroom nearby was in pathetic condition. The discharge system of biotoilet was not working. So, the whole toilet was filled up in the UP train itself. And they did nothing at NDLS or MB(after complaining) to fix it. The coach was dirty like anything. The train was delayed by 14 hours till i reached my destination.
