This train is actually for ppl of Solapur who don't get seats in siddeshwar Exp and it use to be idle at SUR and also PM at Mumbai so they extended upto Gadag that too with very less quota. If it needs to be extended up to Ballari then it's timings should be changed and mainly CC should be increased else no use of extension up to Hospet or Koppal also. Better they should start New Train to Mumbai via Ballari Hospet Koppal with good reservation quota. Instead of this Mini rake Extension to Ballari..
