I don't want to blame any zone, plus I'm not from any of these zones. Neither fan of any of these trains. As a fellow IRI member, I doubt myself why coaches of Purshottam Exp is very poorly maintained and I mean it 'VERY POORLY'. Few days back I saw train at KGP. Whole train was in a such terrible condition. When we see other SF LHB trains such as Sampoorna Kranti Exp, Mahabodhi Exp, Poorva Exp (saw at NDLS in dec) or even kabirdham Exp; they are far better maintained then Purshottam.
