MUMBAI, India, May 29 -- Intellectual Property India has published a patent application (202611051276 A) filed by Indian Institute Of Technology, New Delhi, on April 22, for 'a method and a system for designing a railway track formation.'
Inventor(s) include Manna, Bappaditya; Haldar, Suman; Chatterjee, Shashwata; and Bhattacharya, Debayan.
The application for the patent was published on May 29, under issue no. 22/2026.
According to the abstract released by the Intellectual Property India: "A computer-implemented railway track formation design method and system determines a blanket layer thickness based on operational and subgrade inputs. A user interface receives an axle load, a train speed, a subgrade classification, and an allowable settlement criterion. A processor accesses stored regression relationships correlating blanket layer thickness with formation settlement, ballast-layer stress, and subgrade stress, the relationships being derived from validated numerical and experimental studies. The processor computes a blanket layer thickness, verifies whether the computed thickness satisfies settlement and stress criteria, and outputs a blanket layer thickness recommendation. In some embodiments, the system further displays predicted ballast and subgrade stress values and graphical design relationships for selected operating conditions. The disclosed approach enables rapid, scenario-specific blanket layer design for freight, passenger, mixed-traffic, high-speed, and heavy-haul railway applications while reducing reliance on repeated standalone numerical analysis during routine engineering use."
