Garib Rath isnt concern for Mau & thats why you lamented its diversion!!
UMB-DLI train will always be ASR-JAT bound & with Delhi as Intermediate, you cant doubt it to be a crowd puller (even without PNP as 12379/04692)!! Worker/Laborer move 1000 Kms to work & cant move mere 100 Kms to UMB!!
4 Trains Ex PNP apart from Saryu Yamuna: Unchahar: LKO-CNB Region, Muri: BSB-ALD Region, Amrapali: LKO-GKP-Bihar, GR: MB-LKO-GKP-Bihar (Economy AC)
