The very first train to run with E-loco on this route was back in 2014, 12382 Poorva Express with HWH based 30458 WAP7, covered the whole stretch in whopping 2 hours and 20 mins...I couldn't believe it...
That's was impressive, when earlier Gangakaveri Exp used to cover the same in 3+ hours...
I was onboard and very delighted to witness that.
