दौड़ती है हिमालय तट से सागर, हमसफ़र हर राह पर, हवाई जहाज़ों को त्याग कर, करो अक्सर, भारतीय रेल में सफर. - Arpit P

Found something interesting and crazy about this train. 12554 Vaishali express had already brought an Electric loco in newly electrified CPR-BJU section, that too in JANUARY 2015 !!!!!!!!!! You heard it right, Yes it is 29-January 2015..........
So there was already some sort of trials of Electric Locos with this train approx 2 yrs ago.
