In ghat sections or high gradient, banker are been provided not for pull/push support (as power enhancer, as used to be an historic concept), as now LOCO are equipped with high power, but just to support from back, so that couple break chance minimizes (as on moving onto higher altitude, the couple gets the load of coach on them)!!
#
PS: If u find any short rake train, its not been provided with banker, as the load isnt that much which may cause danger on couple load!!
