one more difference in icf rakes...ec has a separate hand rest for both hands where as in cc the handrests are to be shared by adjoining pax like in movie theatres...not sure of lhb rakes though...and tejas sir,i was the one who had given the illogical logic of cleaner toilets even at that time...i had also complimented my statement by saying that less pax,less occupancy,less queue and easier access to toilets...listening to this some other member commented,pax from adjoining coaches may come and use this toilet...i had no answer to this,hence i opted for the best option i had at that time...i logged out:)
