Railways to expedite ACDs’ installation

Railways has decided to expedite installation of Anti-Collision Devices (ACDs) at all vulnerable places across the country to prevent mishaps on tracks. Trials and retrials of the ACDs are being held to ensure their effectiveness. Railways has almost made a breakthrough on this front after making a slight modification in the design and structure of the devices.

The newly-developed device is a foolproof system to prevent head-on collision on tracks. It is so sensitive that it will give an alert signal to loco pilots of both the trains if they are running on the same track, enabling them to prevent a mishap, according to a Railway Board official.

According to chairman of Railway Board (CRB) Vinay Mittal, railways is fully committed to ensure foolproof safety on tracks. It is with this aim that the railways has been conducting trials of ACDs at various places to check their effectiveness. Though the device is a bit complicated, railways is hopeful of its successful introduction across the country. An expert team of railways recently conducted its trial in Southern Railway and North Frontier Railway. These trials were successful. Earlier, the ACDs were successfully tested on Katihar-Guwahati-Dibrugarh-Ledo section of North East Railway. It was also tested on the Jalandhar-Amritsar route. Now, the railways would install this device on a priority basis at all vulnerable places in different zones of railways, Mittal said.


Railways testing improved anti-collision devices news

The Indian Railways will conduct the second set of equipment proving trials with modified anti-collision devices (ACD) on the electrified, multiple-line automatic signaling section on the Chennai-Arrakonam section, in Southern Railway, from 10 November 2010.

The Railways conducted the first set of trials in the same section in September-October 2010.

The trials are aimed at providing a fair opportunity for success of the indigenous technology, an official release said today.

The release said the equipment has been modified in respect of several software and hardware parameters on the basis of feedbacks from the first trials.

The modified devices will now be tried out in the second set for making headway in achieving the objective, it said.

Railway minister Mamata Banerjee has assigned the highest priority to safety and security of passengers.

Rail test on collision buster

The Indian Railways has eventually decided to conduct trials on its anti-collision device from next month to see if it can be installed nationwide.

It has hinted that the years of delay in the country-wide installation of the device, developed almost a decade ago, had to do with the huge costs involved.

The railways were criticised after experts said the anti-collision device or ACD could have prevented last month’s train collision at Sainthia, which claimed 62 lives.

“We plan to test the anti-collision device in Arakkonam area of Southern Railway from September 1,” Railway Board chairman Vivek Sahai said. “After a month’s trial, depending upon its performance report, the railways would look at implementing it across the nation.”

Told that the device had proved its worth in Konkan Railway and North-East Frontier Railway, the only two zonal railways where it has been installed, Sahai said: “They are working on a single track. The testing would be on multiple tracks with automatic signalling and other differing parameters.”

Asked about the years of delay in testing the device on multiple tracks, he said: “The cost of implementing the project is huge. It would cost Rs 2,500 crore for the devices to be installed across the country. It would cost about Rs 15 lakh to be installed in a single locomotive and around Rs 7 lakh per station.”

India has about 7,000 locomotives and a similar number of stations, which would translate to Rs 1,540 crore for the ACD installation. The official did not explain where the other Rs 960 crore would be required.

The ACD works on the General Packet Radio Service, which is used in mobile communications. When installed in train engines (along with an auto-braking unit), guard vans, stations and level-crossing gates (both manned and unmanned), the network of ACD systems prevents collisions. It automatically brings a train to a halt if the track ahead is not clear. The train starts braking 3km ahead of a blockade or barrier.

The railways had developed the ACD after the Gaisal accident of 1999 killed 268 people. Experts have said the technology has been ready for country-wide use since 2003, and questioned claims that it may not be effective on multiple tracks, citing certificates issued by foreign agencies.

Railway minister Mamata Banerjee had in January 2000 climbed into a locomotive during the testing of an ACD. She then gave the green light to the project. The Railway Board had earlier said the device would be installed country-wide by 2009 in a phased manner.


Konkan Railway completes 11 years


Friday, 23 Jan, 2009

Konkan Railway will be completing 11 years of the commencement of its through line train operations on January 26th 2009.

It was on this day in 1998 that the trains directly connected Mumbai with Mangalore in shortest possible time, reducing the travel between these places from 36 to 16 hours.

In the 11 years, it is the first time that Konkan Railway has not reported any consequential accident on its route in 2008. Konkan Railway has achieved this feat by taking extra efforts to increase safety on its route by executing massive earthworks, widening the slopes, planting lakhs of Vetiver grass as soil erosion control measure, and various other geo-tech works to arrest boulder falls and soil slippage during the monsoon. The efforts have borne fruit. There has not been any major traffic disruption on the route in the past 3 years since the time these massive safety works were executed and a special Monsoon Time Table implemented on the route.

In these 11 years, Konkan Railway has also made significant strides in train operations and innovations. The innovative Anti-Collision Device, a patented technology of Konkan Railway is being implemented in phases over various zonal railways in India. KRCL has now formed a special `ACD Task Force’ to tap the immense potential that ACD has in the domestic and the international market.

However, Konkan Railway has also brought a financial turnaround in the last 4 years, displaying a significant increase in its earnings, total surplus and achieving the lowest net loss and highest Operating index so far. In the past, the World Bank has appreciated KRCL’s practices to bring down the cost of operation and maintenance and termed it a benchmark for others to follow. Further on, Konkan Railway aims at fostering marketing strategies for commercial implementation of its innovative technologies far and wide and nurture efforts to make the Corporation a profit making unit.
