Linking MML and HBG was always difficult due the the curves. HBG can be developed as a DEMU/MEMU shed so that DEMU/MEMU's can run from JBP to other near by cities. In ideal world, Adhartal would have been a better choice for terminal instead of MML due to availability of space.
MML me agar terminus banana hai toh Kachpura me hi yard banana padega, otherwise Adhartal se daily trains JBP station cross karke MML aaengi/jaengi. Jo ki befizul me JBP ka congestion increase karega.
