LUCKNOW: Alert loco pilots foiled attempts to derail two major trains running from Delhi – Rajdhani Express and Kathgodam Express– by placing wooden logs on the track in UP’s Hardoi district, police said Tuesday. Though there was no official statement by the Indian Railways, the two incidents are being probed, and efforts are on to identify and arrest the culprits.There is no clarity yet on any terror angle to these sabotage bids.“Unknown men had tied wooden blocks to the railway track between Dalelnagar and Umartali stations using earthing wire on Monday evening,” said GRP SHO, Hardoi, Jaiprakash Singh.Police said the first attempt was made around 5.45pm, when the New Delhi-Dibrugarh Rajdhani Express was heading towards Lucknow. A likely disaster was averted as the loco pilot applied the emergency brake after spotting the obstruction. He removed the wooden logs and informed the railway officials.Another attempt was made soon after, around 6.30pm, to derail the Kathgodam-Lucknow Express on the same route. This time, too, the loco pilot stopped the train in time, and removed the obstruction before proceeding towards Lucknow.After the two incidents, GRP and RPF teams, along with maintenance staff, inspected the track. The section was declared safe for train operations by 7.30pm. An FIR has been registered against unidentified persons on a written complaint filed by railway authorities under section 150 (maliciously wrecking or attempting to wreck a train) of the Railway Act.
