Bihar is going for Election next year 2020.
New trains from Patna, Bhagalpur, Saharsa, Muzzafarpur, etc is expected soon. 2020 budget will see good allocations for Bihar, new projects and trains, budget allocations increase for existing projects, Patna Metro is a good initiative.
I think 2020 will see many new trains for Bihar, West Bengal and Assam.
