Already one Post i have written that there should be a new double electrified railway line between Mughalsarai - Bikramganj - Arwal - Jahanabad - Bihar sharif - Sheikhpura - Lakhisarai. It will speed up the train originating from Northeast States and also from Bhagalpur, malda & Farakka. It will cut short the time of Long distance trains. Bikramganj, Jahanabad & Bihar sharif should have Elevated Railway tracks then only it can speed up trains without any late. They can have elevated stations if in need.
