According to sources, this project was duly sanctioned by the Railway Board during Nitish Kumar's tenure as railway minister to maintain smooth flow of traffic on the mainline route, particularly between Bakhtiarpur and Barh stations. Besides, railways would run at least four to five coal laden rakes daily from Tilaiya to Barh via Rajgir-Bakhtiarpur section of the division. The sanctioned flyover track is a 20 km stretch between Bakhtiarpur and Barh.
According to sources, it will be the only flyover track carrying coal wagons in such large numbers as far as from Tilaiya to Barh to cater to the needs of the power station.

The railways, however, intends to segregate a separate line from the Bakhtiarpur yard to the power station for the time being to maintain supply of coals uninterrupted. Since completion of the flyover track will take time, the railways proposes to build a separate line from Bakhtiarpur to Barh as a temporary arrangement. This has become possible following completion of the new lines between Rajgir and Tilaiya at a cost of Rs 230 crore, sources said.
It may be recalled that commissioner for railway safety (CRS) R P Yadav recently inspected the newly built Rajgir-Tilaiya lines. CM Nitish Kumar had demanded early opening of this line while flagging off two new trains from Patna Junction recently.
