Nagpur: The Nagpur division of Central Railway has, for the first time, commissioned electronic interlocking signalling (EIS) system at Bharatwada station near Nagpur for smooth and accurate train operations.
The electronic system is a shift from conventional route relay interlocking (RRI) system. The existing signalling system at Bharatwada was 30 years old and needed to be replaced.
“We plan to install similar system in Godhni. The advantage of EIS is that operation time of trains can be regulated to seconds,” said Manoj Kumar Sinha, senior divisional signalling and telecommunication engineer (Sr.DSTE).
Of the 101 railway stations in the division, only two – Gudan Khapa and Tadali – have the age-old level pulling system, while 94 have panel interlocking (PI) systems, five stations – Nagpur, Amla, Ballarshah, Sevagram and Ajni- have RRI systems. Of late, the Railway Board has decided to gradually shift to EIS. To start with, small stations are being taken up first to gauge its success.
Sinha said EIS was a microprocessor based system occupying less space. It consumes less power and is more reliable, safer and easy to install and maintain.
“The conventional systems require large number of relays, complex wirings, thousands of soldered joints and they are susceptible to failures,” said Sinha. After its installation on October 28, no signal failure has been reported. The staff was being trained to operate the new system, he added.
Divisional Railway Manager (DRM) Brijesh Dixit was himself keen to expedite installation of the system. “The EIS was commissioned in three hours while it takes days for commissioning conventional signalling system,” Dixit said.
Sinha said the best part of EIS was that it had a standby facility and could be operated through conventional operating panel.
