One big shortcoming in this diary, its a different thing that I am travelling upto Bptad from where I will shift in Mahuva-ST, but those going by BVC-ST Link Exp will not be able to continue with the trip diary after Surendranagar as this train as per IRI is BVC-DHG, therefore, some systematic correction is really required so that for reservation class the train which system catches is BVC-ST Link Exp.
