Indian Rly to use infrared camera system to check derailments on high-speed sections

New Delhi: Indian Railways for the first time has decided to use Rs 75 crore photographic inspection systems on tracks to check derailments on its ambitious Rs 18,000 crore project for increasing train speeds on the two busiest Delhi-Mumbai and Delhi-Howrah rail sections.

The two projects have been approved in Railway Budget and likely to cut down travel time between the three metro cities by 2019. The plan is to install photographic inspection systems at 10 locations each costing Rs 7.5 crore on the entire section to get photographic data of wheel profiles.

Several railways across the world use the photo diagnostic system and it will be used for the first on these two sections in Indian railways, said a senior official of railway ministry.

“The Railway Board is in process of finalising the stations on Delhi-Mumbai and Delhi-Howrah section where these units have to be put. We may have to acquire these units from companies abroad,” said the official.

The system is designed to monitor axle, wheel, brake temperatures and to indicate any overheating which could lead to derailments and transmits this data to the traffic control and monitoring section. The real time software possesses the intelligence to process the recorded data and produces the report with axle wise temperature information and transmits the data to control room.

“The system will have high definition infrared camera and will send live pictures of any wheel abnormalities to control room at the nearest station. Besides, it can also check if any extended material like doors of freight wagons hanging or any other material on the track and these can be corrected immediately,” the official said.


Recent derailments have concerned top officials at Railway Board and they want all precautions and technology interventions in place for a train running at 160 kmph. The project will see major infrastructure upgradation of the signalling system, fencing of tracks in certain areas, elimination of all level crossings and installing train protection warning system.

Chennai: Chennai Metro Rail Limited has officially released a route map for its ambitious phase 2 metro project that will connect far-flung areas of the city through three corridors. In February, Metro Rail floated nine tenders for detailed design consultants and for soil tests. In one of the tenders, it has released a map of phase 2 with 104 stations, covering 107km. The estimated cost of the project is Rs 85,047 crore. Chennai Metro Phase II Network Map (PC: CMRL) However, after a review of the alignment, CMRL officials said they had increased the number of stations to 116 covering a total 107.55km along three corridors. The tenders CMRL has floated are also for corridor 3 (Madhavaram Milk Colony to Siruseri SIPCOT) that covers the IT hub on the OMR and corridor 5 (Madhavaram to Sholinganallur). Corridor 4 that connect Light House to CMBT is likely to be extended up to Poonamallee at an additional cost of Rs 3,850 crore. A feasibility study is at present und...

Innovative SkyWay technologies: Future Transportation

Image
SkyWay string transport is an energy and transportation communicator of elevated overpass type. It uses electric vehicles on steel wheels riding on specific string rails. The main design differences of this system from other types of railroads of trestle design are pre-stressed tension of the structure, the absence of a continuous solid roadbed, low materials intensity in construction and visual simplicity. The main advantages are economic efficiency, environmental friendliness, durability, reliability, safety and, consequently, high market competitiveness. SkyWay transport is developing in three main areas: high-speed intercity type (up to 500 km/h, and in future, up to 1250 km/h with the transition to a pre-vacuum tube) urban passenger type (up to 150 km/h) and freight type. It has no analogues in its field with the ability to meet the entire range of transportation needs. In future it can be integrated into a unified global energy, information and transportation network, which will ...

Delhi Metro | DMRC to make phase-III project fully operational by March 2018

The Delhi Metro’s Phase III, an ambitious public transport intervention, will be almost fully operational by March 2018, bringing vast areas of the national capital into the fold of its fast expanding network. Stretches of the Pink and Magenta Lines, which will together measure over 90 km with 61 stations, will be thrown open starting this October and the entire corridors will be functional by next year. The 58-km-long Pink Line, which will connect Majlis Park to Shiv Vihar running along the arterial ring road that encircles the city, will be opened in stages between December 2017 and March 2018, according to the latest Phase III status report. However, a section of the corridor between Nizamuddin and IP Extension in East Delhi may not be operational by March as it is stuck due to issues pertaining to land acquisition. “The date for Nizamuddin to IP Extension section will be worked out after resettlement and rehabilitation issues at Trilokpuri are settled,” the report ...
