Oscillation Monitoring System (OMS) to monitor railway tracks

Owing to the rising number of accidents, the Railways has come under scrutiny and pressure to adopt safety measures.

As a result, a modern instrumentation system, based on automatic detection techniques, to monitor track irregularities has been adopted.

After certain trials, the Ambala Division has approved the Oscillation Monitoring System (OMS) for maintaining tracks and railway vehicles (coaches, wagons and locomotives).

“Keeping pace with technology, the Railways has adopted a state-of-the-art system to detect the condition of tracks and railway vehicles. OMS is an advanced portable instrument which continuously measures vertical and lateral accelerations at any desired location on the floor of a carriage while in motion,” said Ambala Divisional Railway Manager (DRM) H K Jaggi. The Division has already conducted successful trials on the system from Kalka to Ambala and Ambala to Jalandhar section.

The DRM said the system was running under trial in other sections too. “With favourable results, the system has been gradually applied to more sections in the division, including Chandigarh. This would be further increased in the coming months, gradually covering the entire division,” added Jaggi.

Till now, the track and railway vehicles maintenance was done manually, which consumed more time and labour.

The technology was developed last year by Central Scientific Instruments Organisation (CSIO), Chandigarh.

CSIO Director Dr Pawan Kapur said, “OMS helps to detect deterioration and stress patterns of the tracks, if any, which has great significance as detection is important to avoid an accident

The OMS technology is said to play an important role to facilitate high speed trains, which the Railways has proposed, as they require constant monitoring of tracks.

Rlys to roll out track management system

New Delhi, Nov. 20 Indian Railways is introducing Track Management System (TMS) to help field engineers in optimal, efficient and effective resource allocation (man, machine and material) and decision making.

Six divisions have been identified to implement the TMS facility on a pilot basis. The Centre for Railway Information System (CRIS) has been charged with the responsibility for procurement of requisite hardware and software for this work. This information was given by the Minister of State in the Ministry of Railways, Mr. K.H. Muniyappa in a written reply in Lok Sabha today.

Track management system will work as a useful tool to make the inspection more focused and objective. Indirectly, it will also bring out the effect of heavy haul trains on the track.

Depending upon the results of pilot project, decision on TMS’ rollout on entire Indian Railways shall be taken, said the Minister.

In addition, Railways have also taken following steps to ensure longevity of Railway tracks – use of concrete sleepers, use of heavy section of rails, development of corrosion resistant rail by improvement of metallurgy of rail, anti corrosive treatment of track components, rail lubrication, improved rail pads and ballast deep screening.

The Minister pointed out that the other steps to increase longevity of railway tracks include introduction of wheel impact load detector, change of alignment of train toilet chutes so that discharge does not fall on track rails and track fastenings, trial with environment friendly coach toilets and weigh bridges to ensure overloaded wagons are not present in goods trains.
