I travelled on 2A class on March 23.
The train was brought into YPR Jn almost an hour before departure but the Airconditioning did not start till we crossed Whitefield (15 mins after departure) - the heat was oppressive.
The seats had a thick layer of dust and grime, the plastic table was filthy with what seemed like dried sauce. On pointing this out the attendant reluctantly brought a dirty towel and indicated that I would have to clean up the dirt myself !
Later...
more... I saw the coach was of 2009 make.
