Is there any facility to check coach position of running trains?.. Many times the coach positions are altered.Passengers at small stations, especially at stations where coach positions are not displayed,face many problems.Halt at such stations is also very short.Today @train no 11072 B3 coach position was displayed at no.18 at Indian Railway site where i confirmed my PNR status.On arrival at Raver B3 was at no.6.Train halt of one minute.One can imagine the hassle.Please guide me what can I do in such conditions?
