Alert rly driver spots crack, averts mishap

A major train accident was averted near Dharmapuri on Sunday morning after a crack that developed on the railway track between Palacode and Marandahalli in Dharmapuri district was spotted in time. The pilot of a passenger train reported to railway officials after he heard an unusual sound coming from the track while he passed through the damaged area, railway sources said.

A passenger train was plying between Yashwantpur near Bangalore and Salem railway junction. “The train usually leaves Salem railway junction at 5.20am and reaches Yashwantpur at 11am. It departs from Yashwantpur at 3.45pm and reaches Salem at 9.30pm,” said an officer from Salem railway division. On Sunday, the train was heading towards Yashwantpur when the pilot noticed the anomaly. “The pilot immediately informed Rayakottai railway station,” the officer said.

Railway officials found a crack on the track due to bolt damage. A bolt was fitted to connect tracks and the track was welded along with the clamp. But the bolt was damaged due to poor maintenance. When the train was crossing that particular area, the welding was damaged, resulting in a crack on the track, the officer said.

Technical staff sent from Bangalore repaired the track. Traffic was held up for about an hour and many trains between Bangalore and Salem were rescheduled.

Two firms get nod to install train collision prevention system

Railways has finally selected two firms for installing the much awaited Train Collision Avoidance System (TCAS), the safety mechanism to prevent accidents, in the 200-km-long Vikarabad-Bidar section as a pilot project.

Medha Servo and Kernex Microsystems were selected among six contenders, including a few multinational companies, by the Research, Designs and Standard Organisation (RDSO) of the Indian Railways on behalf of the Railway Board, a senior Railway Ministry official said.

The pilot project, which aims at preventing accidents, is estimated to cost about Rs 18 crore while the trials on Vikarabad-Bidar section in South Central zone are expected to be completed in about eight months time by February 2014.

A safety device designed to prevent train accidents, TCAS is based on a combination of railway signalling data with radio communications, global position, radio frequency identification devices, software and logic.

The indigenously developed TCAS is a combination of Train Protection Warning System (TPWS), an European technology which protects trains against signal passing at danger, and Konkan Railway-developed anti-collision device which avoids collision in mid-section.

“TCAS is developed in RDSO and it is very cost effective for us. While TPWS cost about Rs 70 lakh per km, TCAS is just about Rs 10 lakh,” said the official.

Fitted with a Global Positioning System (GPS) and Radio Frequency Identification (RFID), the device would automatically activate the brakes if it detects any problems on the track.

After a successful trial in the South Central zone, TCAS will be deployed all over the country, said the official.

TCAS is equipped to control railway stations, signalling systems and trains including suburban, long-distance and goods trains.

The official further said that whenever TCAS has to bring the train to a halt, it will first reduce its speed and identify the nearest signal within the range of 200 metres with the help of RFID.

“It will then ensure that the train stops close to this signal.”
