They should if they are sensible enough. Once I was travelling in 12802 from NDLS and as per IRI my coach B1 was the first coach, so I stood accordingly at NDLS, but when the train arrived, the rake was reversed, I travelled back till the end of the platform since it was the last coach now. Late got to know that only Rake no. 2 is running with reversed arrangement. for puru also, any 1 day, if that rake is brought to NDLS from GZB via DLI, whole problem will be solved, but these IR people are lazy!
