I would shortly leave for the site," he added.At least 27 people were killed when two trains derailed in quick succession and some coaches fell into a river in Madhya Pradesh's Harda district, authorities said on Wednesday.One of the trains was the Varanasi-bound Kamayani Express, which met with the accident at about 11.20 p.m. Less than 15 minutes later, the Mumbai-bound Janata Express on the other track also met the same fate - at that very spot.
