LUCKNOW: To ensure speedy delivery of essential items to states during the ongoing lockdown, Railways have started operation of ' Annapoorna ' and 'Jai Kisan' special freight trains.The trains have delivered essential goods to states like UP, Assam, Bihar, Goa, Gujarat, Karnataka, Maharashtra, Manipur, Nagaland, Odisha, Tamil Nadu, West Bengal, Mizoram and New Bongaigaon (NBQ) in NFR.Annapoorna trains are almost 5,000 tons super heavy trains and as long as about 80 rakes. The 25 such trains operated by Northern Railway (NR) between April 1 and April 16 have transported more than 3.2 million tonnes of foodgrains.The Jai Kisan specials, on the other hand, are two freight trains loaded from two different originating stations and clubbed at the nearest junction point to operate as one common train till the last common station possible before they take diverse routes to their destination stations.That ways, the track is not blocked and both trains continue to move. This drastically reduces the journey time of the freight trains to their respective destinations.Under normal circumstances, one freight train containing 42 covered wagons loaded with food grains carries around 2600 tonnes. But, Jai Kisan special has double the capacity.
