Saurabh Ji who is IRI Admin (#15807) from ALD has showed me a news item stating that initially Freight Trains will be tested with Electric Locos between MGS & MB via SLN - LKO - BE for around 6 Months starting from Feb, 2013. When the CRS Team feels satisfied then even Passenger Trains might get Electric Locos like
WAP-5 between Calcutta and Amritsar :-)
