Extending GG to PVR is bad move which better not have asked. Already Golgumbaz Exp lost it Historic essence by Extending up to Mysuru which was once prestigious train between Solapur and SBC. Already PVR YPR they running so instead Extension better asked Ballari Pandarpur Exp.. Regarding Mumbai Gadag Exp it is easily extendable upto Hospet with speed up and slight change in TT.
