No, it's not that Vaishali. Katihar waali jo Vaishali hai wo baad me Siliguri se Kathgodam chali wo MG train thi. Jo Vaishali Abhi chalti hai wo Jayanti Janta express k naam se introduce hui thi from SPJ to NDLS via Mokama, Patna, MGS. Baad me SPJ-MFP broad guage hone per ise MFP se via SPJ Chalayan gaya. MFP-GKP guage conversion k baad ye via Patna na ja k via GKP jaane lagi or MFP se BJU shift ker diya.
