thanks all for reply...as u said above some touts may be using the service in negative way but it will be very helpful for old age passengers and as all knows and seen on star news and zee news today u cannot stop touts and illegal agents because corruption is everywhere....waitlisted passengers cannot board the train whereas without ticket can get full berth by giving some 50-100 rs to TTE...u can't stop them...My point is for additional facility to the passengers ....
