Allotment of ALCo or EMD is not done only for purpose of increase in Speed. This logic is totally flawed! If yesterday Karwar ICE got Alco n next week it gets EMD, what will you expect? Should it be before time at all stations? Please understand that allocation of loco depends on various factors, things that are far more important than being called 'Useless' or 'Useful'! So if you have any better logic to substantiate your claims, continue, else kindly refrain from commenting!
