12212 Anand Vihar-Muzaffarpur Garib Rath Express

12703/12704 Faluknama Express that run between Howrah and Secunderabud are definitely the fastest connect between these two metropolis. The current run time of 26h+ can certainly be squeezed by 2 hours. The upkeep of certain rakes on this important route is far from satisfactory. As a frequent traveller on this route, I have noticed that the service standard i.e. cleaning frequency, spray on curtains, mosquito repellent use, etc in the rake is better if the rake is well maintained. Why the rail authorities are not considering a Duronto service on this sector?
