There are some trains which are not having that end to end GNWL from MAS. Example Coromandal, Hwh mail, GT ( Even from GDR to NDLS its GNWL). Even VM-KGP, VM-PRR, PDY-HWH, PDY-BBS all these have nit end to end GNWL.
Its followed for only some trains, but here DVD, AKP is part of Vizag dist its better to provide GNWL atleast to AKP.
