People from Asansol already board this train from Adra. So do the passengers from GMO, BJE side using GMO KGP Exp. Adra is particularly well connected to Asansol. This train Is well rooted deep inside the Jangalmahal's emotion as their "Vellore Gadi". I doubt any extension of this train.
Similar diversion demands from Ranchi have been prevalent on Samarsata Express, Kaviguru Express etc. all of which were turned down.
