I think that 12358 has been mistyped as 13258 since information states about a train traveling from Amritsar to Kolkata. There can't be a huge error in the typing of places that a train is serving... let's give Jagran Newspaper a benefit of doubt. Similar chain pulling incidents on this train have taken place before
near Bareilly and Dehri-On-Sone also in the past few months ;-)
