What is the issue then ? In a station like Howrah ,Platforms 8-14 and 17-23 can accomodate trains with more than 25 coaches easily.Again we already have 3 AC-3 tier coaches and 8 Sleeper coaches. where as there is only one 2A coach. Nor sure why my fellow blogger mentioned that 2 SL and 1 AC-3 tier coach demand is more and needed before 2A.
