one thing i want to clearify..previously purushottam runs with icf rakes with 110km/hr and it always been on time..as it got lhb the speed has been increased by 110 to 130km/hr its getting late on avg 2hr on both up n down run..so wht is the benifit of increasing speed ???
just by saying that we increasing speed it is necessary to complete journey om time n in less time in comporisom to previous one then it will b some benifit of lhb coaches
