Considering my overwhelming positive experience recently in Ratna ! , I still track out every run to see the delays getting piled up to ludicrous levels, I have explicitly advised my family, relatives and dear friends to positively avoid the BNR line and the HWH-CSTM line at all possible costs. It is much better to circumvent this entire route by either going via RNC or the HWH-PRYJ-CSTM route. Atleast if not time, your sanity will definitely be preserved...
