MST holder travel in sleeper class is common in this.. once i had booked to adi and got SU seat & SL seat is for one aged ladies.. we both from borivali. but when we board at borivali already 2 persons seated in side lower and 2 on side upper.. when we ask for our seat one from side upper come down and seat in side lower and when ask aged ladies as she can not seat for long time they give pathentic answer as SHE CAN NOT SLEEP AS SLEEPING TIME IN COACH FROM 10.00PM AND same replay to me who seated on side upper... it is ok to seat for me till dahanu road .. but they dont even thought about aged ladies and don't give seat to sleep...
