i think Bandra ( T ) - Bhuj AC Express/22903 shold get halt at samakhiali junction because of following reasons.
first it is entry gate of kutch
second it is junction from where people can change train and go towards radhanpur and rapar.
third samakhiali is 53 kilometer from gandhidham( which is halt of this train after ahmedabad)
forth...
more... train may get technical halt at this station because of single track between samakhiali and viramgam.
fifth train is made for kutchi people so it should halt at maximum stations in kutch.
