A month and a half after more than 140 passengers died in a train mishap near Kanpur, the Ajmer-Sealdah Express derailed in the same district on Wednesday morning, causing injuries to over 60 passengers. From 2003 to 2015, 239 accidents have happened on the network of the Indian Railways and 208 of these — or 80% of all accidents — have happened because of derailments, says the parliamentary standing committee report presented last month.
