Funny that this is an ISO certified train; don't get me wrong, but it is a weekly running between Gaya and Chennai[a medium sized city and a mega city]. Isn't it more logical[since more passengers will be benefitted] to make ISO certified[thus having minimum standards of cleanliness and service]other daily trains running between more major cities[Heck, even Gorakhpur-Asansol is ISO certified for some reason].
