The measure is expected to help Indian Railways speed up trains and to achieve its future objective of reducing the travel time between Delhi and Howrah to about 12 hours from the existing 17-19 hours.
Grand Chord is part of the Howrah-Gaya-Delhi line and Howrah-Allahabad-Mumbai line. It acts as a link between Sitarampur, (West Bengal) and Pt. Deen Dayal Upadhyay Junction, Uttar Pradesh, and covers a stretch of 450 kms falling in North Central Railway (NCR) Zone of Indian Railways, which maintains and operates 53% portion of this New Delhi-Howrah route. This achievement becomes possible by replacement of the 65-year old outdated Mechanical Signaling System with the most advanced and safer Electronic Interlocking System at Tundla station in Uttar Pradesh now.
