Because there are many factors that ruin the passenger growth. The station is far away from main city and we all know about the transportation system and dominance of auto rickshaws. The fare to reach station is too much and people prefer bus for local connectivity rather than spending more on reaching station than train ticket's cost. The only passengers that come to the station are long distance travelers but then BKSC does not have many long distance trains. People prefer bus for Bihar/Bengal than trains. The local connectivity is also not good with district HQ like Phusro, Bokaro Thermal, Gomia, etc.
There is a need of cheaper transportation scheme like city buses to the station and auto rickshaws fares need to...
more... be regulated. Long distance connectivity to places like Bangalore, Pune, Ahmedabad, Bhopal, Indore, Jammu, Dehradun, Jaipur, Jodhpur, Mumbai, etc is needed to pull passengers.
