Indian Railways conducting trials of Tri-Netra technology

Union Minister of Railways Piyush Goyal during Question Hour informed Rajya Sabha members that Indian Railways is conducting TRI-NETRA (Terrain Imaging for Drivers Infrared, Enhanced, Optical & Radar Assisted) technology for detecting obstructions on tracks.

Key Highlights

Background: First in 2002-03 India Railways has developed a modern technology and tried it extensively but it was found to be not successful. So the project was aborted and subsequently another technology of Fog-past devices for seeing in fog was developed. Thus, TRI-NETRA system is another attempt by Indian Railways to develop modern technology.

Trial & Test: Indian Railways is conducting extensive trials of Tri-Netra technology so as to be sure that it is perfect in detecting any obstruction on tracks during fog. Therefore without proper testing it cannot be implemented as it does not give Railways the confidence to implement technology.

About TRI-NETRA

TRI-NETRA is abbreviation for Terrain Imaging for Drivers Infrared, Enhanced, Optical & Radar Assisted system.

It comprises of infrared camera, optical camera and radar assisted imaging system for assisting loco pilots in identifying obstructions on tracks, mainly in foggy conditions.

This device is making an attempt during fog via ultrasonic waves by help of which it will be able to detect any obstruction on tracks.

The field trials being undertaken is for proof of concept and its testing on all parameters will be done after its procurement.

Indian Railways inducts first digitally enabled High Horse Power Locomotives

Indian Railways in collaboration with General Electric (GE) has inducted two Digitally Enabled Locomotives based on state of art insulated-gate bipolar transistor (IGBT) technology. The two HHP prototypes locomotives were wholly designed in India under Make in India program and manufactured under Public Private partnership (PPP) through MoU with GE.

IGBT Technology

It has three-terminal power semiconductor device primarily used as electronic switch. It gives combined advantages of high efficiency and fast switching. It offers greater power gain than standard bipolar type transistor combined with the higher voltage operation and lower input losses.

Background

GE is providing locomotive technology to Indian Railway and by 2025, through joint venture company (Indian Railways has 26% stake) it will manufacture 1000 fuel-efficient locomotives (100 per year) for freight traffic hauling. 700 locomotives will be 4500HP WDG4G and rest 300 locomotives will be of 6000HP.

Initially 40 fuel efficient diesel locomotives will be manufactured in GE facility at Erie, Pennsylvania, US and rest 960 diesel locomotives will be manufactured in Marhoura, Saran District, Bihar. It will start loco manufacturing from October 2018. Locos will be maintained in Roza, UP and Gandhidham, Gujarat.

Features GE Locomotive: They are four stroke engine, 12 cylinders, 06 traction motors, Safety features for self-load, AC Dual Cab locomotive, toilet facility, Upgraded Computer Controlled Braking (CCB system), Fuel Efficient locomotive, Electronic Fuel Injection system, IGBT based traction technology, compliant with India’s UIC emission norm.
