PASSENGERS WHO BOOK THEIR RESERVATIONS ON TRAINS EITHER ii SLEEPER/I AC/II AC/II AC do not enquire at the departing stations the position of reserved compartments. At the last minute they run helter shelter to enter into the bogie.Nowdays trains are halted for only 3 minutes for boardig and de=boarding, which is a stupid idea of the Railways.People with luggage it will be problem. Railways take it granted all passengers can manage to board/deboard the trains easily. Need to improve the halt timings.
