Dual Visual Display Units (VDU) with hot standby are being used for seamless train operations in the yard as hot standby provides zero changeover time during one system failure.
This system will result in the fast train operations due to dual VDU. Apart from this, this will surge protection as compared to panel operation due to provision of OFC communication between system and VDU.
Similarly, High Availability Single Section Digital Axle Counter (HASSDAC), another modern technology being used to improve the punctuality of trains and reduces the detention of trains.
East Coast Railway has converted the Down Last Vehicle Checking Device (LVCD) in to High Availability Single Section Digital Axle Counter (HASSDAC) between Kapilas Road and Byree Stations which will improve the reliability.
