Hmm.... it seems that freight trains also pick up their MPS from Gaya Jn Outer towards MGS or DHN. I am waiting for your snaps of Gaya Jn's Platform No-10 after it's launch + 12357 or 12358 Durgiana Express at Gaya... KOAA-JAT Exp/Lal Kuan Exp/Doon Exp/SDAH-ASR Jallianwalabagh Exp are other options :-)
