this train is amusing - i used mmr-hwh on sunday last week found s2- was way back i.e. 3rd coach from back this week i booked choice s-9 again boarded from mmr on sunday at 00.30 hrs ., to my surprise s-9 this time was 4th from last coach - your site or e.train info turned wrong since in week time rake / coach position changes ., even in poorva via patna ex ndls it changes without info
