Giving one minute halt is a foolish ness i understand but there is no need of Loco change. It runs via GNT which is electrified and also upto wadi or solapur it can run with eloco. Now that almost electrification upto Pune is completed it can anytime soon run end to end with eloco. Still SC being major junction should have given atleast 5mins halt. But it's not IRI fault
