I think in sab stations se gujarti hai yahi reason kaafi hai TAGGING ke liye !!!!!
The purpose is that no one misses this special capture with special locomotive.
Every rail-fan from this entire region/route (NTSK/New Tinsukia Junction - LGH/Lalgarh Junction) would love to see this video who lives anywhere on this entire stretch. Atlest Nitin didn't TAG any station out of this route. TAG system is made to provide the flexibility so that more and more people can get connected. Otherwise remove this feature it's useless.
