New Tech To Enhance Safety In Indian Railways
The Indian Railways thrives on IT and one of its recent deployments have been a move to enhance railway safety and lower the risk of derailments. The South Central and South Eastern Railways in Karnataka and Andhra Pradesh recently signed a pact with MRO-TEK to deploy MAPLE 4C to enhance safety of this mammoth network. MAPLE 4C, a Managed, modular integrated Access TDM multiplexer, is already used in some of the key areas of Indian Railways’ daily operations.
According to a company statement, the new technology is playing a significant role in two crucial segments of railway safety in India. Firstly in the area of axle counter system. When a train has to pass from Station A to Station B, axles are counted at both points and matched to ensure that all carriages have crossed successfully. Only then signal for the train to pass through is given. The interface from the counter at every point is analog, which is converted to a digital signal before being transmitted to the other point.
In the earlier days, this information was transmitted through copper cables, which had a tendency of getting cut often. With MAPLE 4C, the signal is converted to a digital format and transmitted through fibre, ensuring total reliability.
“The contract will allow us to deploy our most advanced technology to further enhance the safety in Indian Railways. Our team will continue to leverage our strong technical capability, solid execution and reliable products operation, to further penetrate into the Indian railways and explore international opportunities in order to create value for our shareholders.” S Narayanan, Chairman and MD, MRO- TEK said.
Secondly, it will play a critical role in the area of Voice Logger at Level Crossings. Commands at level crossings are given by the station master to the gateman through telephone. These conversations must be stored so that they can be retrieved later to analyse why the train was stopped. To ensure accurate storage without loss of clarity, the analog voice is digitized and multiplexed and then carried to the Voice Logger through fibre. Madhava M, VP Technology of said, “It was a challenging task for us to bring MAPLE 4C from MRO- TEK technology. When we take pride in the fact that our railways is one of the largest global rail networks, it is essential that we are able to ensure safety of passengers too.”
