highly unlikely that this or rather any train via sbg loop will be provided with lhb in near future. also i personally feel that until the issue of self generating air conditioned coaches is developed by lhb technology, no train (except for full ac trains) should be provided with lhb. its a waste attaching 2eog for the sake of 2 or 3 ac coaches. instead 2 slrs can carry some passengers and huge luggage too
