The decision to have more trains pass through Barauni can be attributed to various factors, including the availability of infrastructure and facilities at the station, historical importance, and connectivity to different regions. While it's understandable that some people may desire more trains to pass through Bhagalpur or Dumka, it's essential to consider factors such as track capacity, demand, and operational feasibility. Congested routes can pose challenges in terms of train scheduling and maintaining punctuality. However, it's always helpful to voice your opinions and suggestions. You can contact the concerned railway authorities through the proper channels and share your thoughts on the matter. They consider passenger feedback and requirements when planning train routes and schedules.
