Enhancing the competitiveness of the railway sector

first_img Citation: Enhancing the competitiveness of the railway sector (2018, June 28) retrieved 18 July 2019 from https://phys.org/news/2018-06-competitiveness-railway-sector.html Enhancing the competitiveness and attractiveness of the railway sector – the core ambition of the Shift2Rail joint undertaking – requires other projects to clear the way. The ROLL2RAIL project played this role by focusing on novel rolling stock technologies and methodologies. Future trains should be more energy-efficient, lighter, more reliable, have more capacity, cost less over their life cycle, be connected and be more comfortable and attractive. Only then will the railway sector be able to raise its market share. Of course, getting there won’t be easy: there are many obstacles to such radical innovation, and technologies with the potential to rise to this challenge are only in their infancy. This is the context that saw the launch of ROLL2RAIL (New Dependable Rolling Stock for a More Sustainable, Intelligent and Comfortable Rail Transport in Europe), an EU-funded project aiming to develop key technologies and remove blocking points for radical innovation in the field of rolling stock. Being part of a wider long-term strategy to shape the rolling stock of the future and ensure suitable results for integration in Shift2Rail, the project addressed several sub-systems including traction, TCMS, carbody, running gear, brakes, interiors, noise and energy.”Traction systems have reached their maximum possible efficiency with current power electronics technology (silicon). Our goal was to reap all the benefits of incipient silicon carbide semiconductor technology to create smaller, lighter, more efficient and more reliable railway traction systems, while at the same time addressing low-floor wheel-motor assemblies for high-speed trains,” Mr Andrea Demadonna, coordinator of the project on behalf of UNIFE (The European Rail Industry Association), explains. “We also studied key aspects of performance such as noise emission or reliability/availability, along with possible technical standardisation that will lead to cost reductions.”In 30 months, ROLL2RAIL achieved a substantial reduction in the weight and volume of traction converters and motors, and produced calculations for motor cooling noise and specifications for a semi-conductor based on environmental conditions.Besides traction, the project led to numerous breakthroughs. The first is a Train Control & Management System (TCMS) that uses wireless technologies for train control and monitoring functions, thereby removing the need for onboard communication cables and simplifying the train coupling procedure. The second is a study on adhesive joints as well as on the reduction in weight linked to composite materials; and the third is a market push for running gear technologies and maintenance – in the form of a Europe-wide cost modelling methodology that can quantify the global impact of running gear performance on the economics of the whole railway system.That’s only the tip of the iceberg, as the project also resulted in the following: a set of reduced and harmonised requirements for a braking system to be used in future authorisation processes; a study of publicly available passenger surveys on train comfort and a weighted flexible scoring metric including 24 comfort features; three new noise separation methods (advanced transfer path analysis, beamforming and wave signature extraction) which were tested in real conditions; and an energy norms and standards application guide for KPI generation as well as a calculation methodology. Finally, the consortium developed a KPI tool to assess the impact/improvements of new developments against a baseline.”ROLL2RAIL results have been designed for use by Shift2Rail as the ultimate end-user. Their benefits will impact not only Innovation Programme 1 (Rolling Stock for passengers) but also advanced traffic management and control systems, infrastructure, freight and cross-cutting activities (CCA) such as noise and energy,” Demadonna says. “Shift2Rail will now continue the work we started, in a process that is only natural when considering that more than half of the ROLL2RAIL partners are also members of Shift2Rail.” Explore further Provided by CORDIScenter_img Credit: Denis Belitsky, Shutterstock Designing the future of rail travel This document is subject to copyright.

Prasad asks Russia to leverage massive potential of Indias digital economy

first_imgPublished on October 05, 2018 India on Friday invited Russia to leverage the potential of its booming digital economy, with IT Minister Ravi Shankar Prasad saying that collaboration in areas like Artificial Intelligence (AI) and e-health would spur technology momentum of both the economies.Prasad said India is pushing its digital economy to touch USD one trillion mark in coming 3-4 years, leading to opportunities in areas like IT, e-commerce, communications and electronics manufacturing.Terming Indo-Russian relationship as one of “trust, understanding and reciprocity”, Prasad said the two sides had a common world view on a variety of matters and that ties have remained immune from the political changes and other differences.“Indeed, it has acquired a new momentum because of personal chemistry and understanding between Prime Minister Narendra Modi and Russian President Vladimir Putin,” Prasad said addressing India Russia Business Summit organised by industry body CII.Highlighting India’s strength in skilled manpower and innovation and Russia’s technology prowess, Prasad said India too offers a vast potential in emerging areas like AI, e-healthcare and e-education and the booming start-up ecosystem.“When I talk of digital economy, it has already acquired a momentum of its own and is creating an opportunity for industrialists, IT experts, IT professionals and start-ups…India is a big start-up movement with over 5,000 start ups. All this presents a larger narrative….I request all of you to join in India’s digital economy,” Prasad said.He noted that the success of India’s IT industry is backed by skilled talent and low-cost inclusive technology. The mobile phone base in the country stands at 1.21 billion with 450 million smartphones, Prasad said, adding that 1.22 billion Aadhaar cards offered residents a verifiable digital identity.“Indo-Russian relationship offers a great opportunity to work together. Russia has outstanding people, innovators…India is also a land of innovators and human resource including young IT graduates…If we have this kind of collaboration and cooperation, Indo-Russian relationship will acquire a technology momentum of its own,” the minister said.

General elections in democracy akin to sacred ritual PresidentGeneral elections in democracy

first_img SHARE SHARE EMAIL Saying the general elections in a Democracy were akin to a sacred ritual, President Ram Nath Kovind on Friday urged all citizens to be part of this ritual by participating in the upcoming Lok Sabha polls.“Each vote will encourage another voter, and each vote will strengthen our Democracy,” the President said at a function to celebrate the 9 National Voters Day. The President said every vote counts equally in the formation of the government, adding that large organisations functions under the Election Commission (EC) to ensure that every voter is able to exercise his or her voting right.“The complexity of the task — beginning with the preparation of electoral rolls and concluding with the declaration of election results — is difficult to comprehend for an ordinary person. Yet, through all this, the credibility of our electoral system has continuously strengthened. Our voters have a firm belief in the integrity, diligence, fairness and transparency of the EC and the electoral process,” the President said.The President was also of the opinion that the country’s size and the logistics of holding elections makes it critical to embrace modern technology.Ravi Shankar Prasad, Minister for Law said there was a need to not only trust but also respect the sanctity of the EC.Without naming any political party, the Minister said the electronic voting machines (EVMs) had also decided the victory and defeat of the party that he represented.Inclusive approachSunil Arora, Chief Election Commissioner outlined the various initiatives which the Commission has taken to ensure that all categories of voters are included in the electoral process.“The Commission has taken initiatives for enhancing women’s participation and the turnout of women voters in recent elections has been encouraging,” Arora said adding that the Commission is committed to making the electoral process accessible to all persons with disabilities.Election Commissioner Ashok Lavasa said the gender gap has come down from 16.7 per cent in 1962 elections to 1.5 per cent in 2014 with women’s participation in the electoral process increasing from 46.6 per cent to 65.06 per cent.
