GUWAHATI, Dec 4: Northeast Frontier Railway (NFR) has successfully commissioned a state-of-the-art Electronic Interlocking (EI) system at Dumdangi (DMZ) in North Dinajpur district, West Bengal, under Katihar Division. The modern Siemens MK-II system replaces the older Panel Interlocking, significantly improving safety, operational efficiency and reliability of train movements in the region.
The advanced system incorporates 45 routes, 33 track circuits, 9 main signals, 8 independent shunt signals, 2 dummy shunt signals, 16 points and multiple vital and non-vital FNmux units for digital monitoring. Level crossings NC-26, NC-29 and NC-31 have been upgraded with Electrically Lifted Barriers, replacing the older manually operated barriers to further enhance safety standards.
