Calling this as a single largest goods train is 'kidding' and childish efforts of IR.
When they are deploing four engines to pull the 180 wagons, it speaks of the weakness of engines. They could have avoided the breakdown, by making four trains of 45 wagons each and proper Single engine.
This is no way to call it largest. The way India boasts of Largest Democracy of the World, people are 'laughing', same is the case with this 'largest train'
