Yes pnbe-sanghamitra express travels through bza route.
As we know there are many people of Bihar living in outskirt of ballari especially in jsw tornagallu. The Bihar people have to change at least two train to move Bihar. Suppose if they divert to run on tumkur-arsikere-chitradurga-ballari route. I think it will be better. Or there should be one more same train on bay-sbc route. Because they have not to change train twice..Give here reply here. I could suggest the people of ballari to demand for this. So that train pressure on VSG-HWH exp, YPR-TATA express and MYS-BSB express the passenger wold reduce..
