BBK - LKO - CNB used to have a thriving EMU system. Now only two EMUs ply. What is there to think about it? First reintroduce what was already there. There is not a single EMU plying between Lucknow and Barabanki now. Earlier they used to ply despite there being a single line between Daliganj to Malhour in NER section [ it's doubled recently ]. They have been stopped for nearly four years.
