Indian Railways installs Asias largest Solid State Interlocking in Kharagpur
November 25th, 2017
Indian Railways has installed Asia’s largest Solid State Interlocking (SSI) system in Kharagpur, which will enable station masters to set 800 different routes for trains in a matter of minutes. Interlocking is a railway signal apparatus that prevents conflicting movements of trains. Asia’s largest Solid State Interlocking (SSI) system has been installed in Kharagpur at a cost of Rs 39 crore. The cutting-edge technology replaces the pre-1989 route relay system that only allowed operators to set maximum 423 routes. The new system ensures that no cross-movement takes place.
