BKSC is a junction in working TTs of SER. The BKSC-TLE-BJE line is used for goods train only and no passenger service on this section.
Ispatnagar which is the closest station to the main city falls on this section and also Chas station is available for the people of Chira Chas and Chas but IR is not serious about it.
Plus, those who are under the impression that the line is used for BSL plant should get their fact corrected that its mainly used for IR freight trains only.
