Actually, I also don't understand what was a big issue in Vande bharat breakdown? Afterall its a machine. At initial stages, WAM4, WAP4, WAP5, WAP7, all failed but WAM 4 and P4 served IR for long and are still doing, and P5 and 7 are the present and future. So should we had stopped them also citing one loco failure or something like that. This is the first set by ICF, give it a chance.
