The plus point of 16227/8 is that it terminates and originates from TLGP which means a direct connectivity to SBC for travellers from Talaguppa, Sagar Jambagaru and Anandapura whereas to catch the other trains originating from SMET they have to come by bus to SMET and then continue the journey by train. That is the reason why Talaguppa train gets filled up first.
