MUMBAI, India, Sept. 28 -- Intellectual Property India has published a patent application (202647111091 A) filed by Hitachi Rail Limited on September 16, 2026, for Control System For A Train Having Two Pantographs.
Inventor includes Wills, Luke.
The application for the patent was published on September 25, 2026, under issue no. 39/2026.
Abstract: A control system is provided for a train having two pantographs raised for collecting power from an overhead line, wherein the control system is configured to perform a number of steps. Firstly, the control system determines, relative to a direction of travel of the train, which of the two pantographs is a leading pantograph and which is a trailing pantograph. Secondly, the control system receives a measurement of a speed of the train. Thirdly, the control system determines, relative to the measured speed, a first uplift force for the leading pantograph against the overhead line and a second uplift force for the trailing pantograph against the overhead line, wherein the second uplift force is greater than the first uplift force, and the difference between the first and second uplift forces is a function of the measured speed in which the difference increases as the vehicle speed increases. Fourthly, the control system issues command signals to the leading and trailing pantographs to respectively apply the first and second uplift forces to the overhead line.
