This train was introduced as 91/92 between Tatanagar and Muzaffarpur( I am not sure about the year of introduction). Later numbers changed to 8181/82 TATA - MFP Express. Then, for a brief period was extended to GKP and ran as 8181/82 TATA - GKP Express. Again, curtailed to run between TATA and CPR as 8181/82 Tata - Chappra Express. And, now runs upto Thawe.
