BENGALURU: Bharat Electronics Ltd, a public sector undertaking, has commissioned the first phase of the real time train information system for Indian Railways to increase its operational efficiency and improve passenger safety.The system has been commissioned through the Centre for Railway Information System (CRIS), under the technical guidance of Space Applications Centre at ISRO.RTIS provides real-time positional information of locomotives to the Railways. It facilitates automatic acquisition of train movement data, including that of arrival, departure and run-through timings, at the stations en route.The control chart of trains , which has RTIS-enabled locomotives, gets plotted automatically in the Control Office Application system of the Railways.The Train Controllers can, without any manual intervention, accurately track the location and speed of RTIS-enabled locomotives and trains. Not only does the system facilitate smooth control of trains, but it also optimises traffic management, improves operational efficiency and pre-empts accidents.The technology of the Locomotive Device has been developed in India . The entire application software, including the HUB Network Monitoring System (NMS), has been developed inhouse by Bharat Electronics.
