China to develop faster high-speed trainsChina will develop faster and smarter high-speed trains offering passengers a wide variety of choices, according to a special plan for the country’s high-speed train technology development during the 12th Five-Year Plan period (2011-2015) recently released by the Ministry of Science and Technology. The country’s high-speed rail development has entered “a second spring” after an “unexpected brake.” Priority given to technological development Smarter high-speed trains The special plan noted that during the 12th Five-Year Plan period, the country will make efforts to improve the safety of high-speed railways, develop a wide variety of intelligent and energy-efficient high-speed trains, ensure the sustainable development of high-speed rail technologies, and master the key technologies for high-speed trains and related equipment. Intelligent technology will allow trains’ monitoring, speed control, condition determination, and fault detection operations to be conducted digitally, said Ding Rongjun, an academician of the Chinese Academy of Engineering and general manager of CSR Zhuzhou Electric Locomotive Research Institute Company. The top speed of a high-speed test train developed by CSR Corporation recently increased from 500 kilometers per hour to 575 kilometers per hour. “The test train integrates various technologies such as Ethernet and the Internet of Things, and can directly determine specific weather conditions. After it is struck by lightning, the train can automatically adjust its speed and optimize related operations to ensure safety,” said Zhao Xiaogang, chairman of CSR Corporation. In order to reduce smart trains’ energy consumption, the country will carry out research in new traction drive technology based on permanent magnetic motors, according to the special plan. Ding explained that the new traction drive technology featuring fast energy transmission and low energy losses can reduce trains’ energy consumption by more than 15 percent as there is no physical contact between the transmission movable parts.
"It is a misinterpretation," Zhao said, adding that the number of overseas orders CSR Corporation has received has greatly increased, instead of dropping, since the Wenzhou bullet train crash. The company's revenue from overseas markets increased nearly 250 percent last year from the previous year. "Foreign markets will be a major source of revenue for CSR Corporation," he said. The special plan said that in order to meet the diverse needs of domestic and overseas consumers, China will customize high-speed trains according to the conditions of different regions and infrastructure facilities as well as different speed requirements. The country will develop a series of high-speed trains for high-speed and conventional railways as well as for export. "The family of China's high-speed trains will be further expanded," Ding said. In addition to existing trains with operating speeds of 200 kilometers per hour, 250 kilometers per hour, 300 kilometers per hour, or 350 kilometers per hour, there will probably be trains with speeds of 180 kilometers per hour or 160 kilometers per hour for inter-city travel. In addition to existing eight-car and 16-car trains, there will probably be six-car and 12-car trains. All these possible changes are aimed at meeting the diverse needs of different clients. Industry insiders noted that China still has a long way to go in developing truly fast and safe high-speed trains. Export business only accounts for less than 10 percent of the total revenue of China CNR Corporation, which is the largest transportation equipment exporter in the country, a relevant official from the company said.
Tunisia Builds Railway Partnership with Turkey and ChinaTurkish and Chinese businessmen expressed their willingness to help Tunisia develop a modern railway network during a meeting held on Tuesday in Tunis with the Tunisian Ministry of Transportation. Mehmet Nazif Gunal, chairman of Turkish company MNG and Zheng Changhong, president of SINOMACH International – a company specializing in railway construction – met with the Tunisian Minister of Transportation Abdelkarim Harouni to discuss means of developing Tunisia’s transportation infrastructure. During the meeting, Harouni presented a briefing detailing the challenges currently facing Tunisia’s transportation sector. “One of the shortcomings is the lack of interconnection between different regions, despite being a small country. This has, in a sense, contributed to the creation of differences between certain regions in terms of development,” he said. According to a statement issued by the Ministry of Transportation, the government aims at increasing the capacity of Tunisia’s rail-transport system. “One of the priorities of the country is to establish a developed railway network and ensure a modern fleet to transfer people as well as goods,” said Harouni. The minister also discussed the anticipated Maghreb High Speed Railway Line ??(LGV), which would connect Algeria to Libya through Tunisia with 800km of railway. Harouni also laid-out initiatives related to the creation of logistical zones in Tunisian ports and the establishment of a deep-water port. The president of SINOMACH International expressed his interest in investing in rail transport projects in Tunisia and providing funding to help the country undertake the construction initiatives discussed during the conference. Gunal, the chairman of Turkish MNG, in turn expressed his country’s desire to encourage investment in Tunisia. He stated that he was “optimistic” about the success of Tunisian-Turkish cooperation in the transport sector, and that the Tunisian business environment is, ”secure and transparent.”
Singapore railway station gets new life as fashion runwaySingapore's historic Tanjong Pagar Railway Station was bathed in revolving shades of orange, pink and purple lights on Wednesday evening. Less than a year after it ended life as an active train station, models sashayed down a makeshift runway to show the latest clothing from Italian fashion house Valentino and show off one of Singapore's architectural gems. The art deco building at the edge of Singapore's central business district, with its murals in the main hall and four marble statues on its portico entrance, closed in June last year as part of a deal that saw Malaysia move its rail operations to a new site nearer the border with Singapore.
ABB looks to North America as China faltersStrong demand for power equipment in North America helped to drive first-quarter orders of $10.4 billion, compared with a forecast for $10.1 billion in a Reuters poll. Orders in Asia, however, fell 11 percent year-on-year, dragged down by weaker demand in Chinese construction and rail transportation markets. Softness in the Mediterranean also weighed on orders in Europe, which slipped 5 percent. "North America continues to look positive on both the power and automation front, while China remains an open question as far as the timing of new investments in key sectors for ABB like construction," chief executive Joe Hogan told a news conference. Surveys earlier this week showed European factories had their worst month in April since June 2009, while China showed some improvement after a muted start to the year. The United States has been faring better, but surprisingly weak jobs data last week raised fears this may not continue. Chief financial officer Michel Demare said he expected a faster recovery in China's industrial sector, although a question mark still hung over the timing of a rebound in the key nuclear, construction and rail transportation segments where ABB sells high margin products like switches and circuit breakers. Shares in ABB were down 3.3 percent by 1248 GMT, compared with a 0.8 percent firmer European industrial goods and services sector index .SXNP. "Positive on North America, but more guarded otherwise," Vontobel analyst Panagiotis Spiliopoulos who has a 'buy' rating on the stock, said in a note. "While investors should focus on solid order growth, the situation at low voltage and power systems and the more guarded margin outlook could weigh on the stock." MARGIN PRESSURE ABB is hoping a global push to upgrade electrical grid infrastructure and use energy more efficiently will drive long-term demand for its products, which are used by oil, mining and utility companies. As the company flagged in February, a backlog of less profitable orders and aggressive price competition hit operating margins in the first quarter, which at 13.9 percent were below the 15.7 percent seen a year ago. Nonetheless, cost savings helped compensate for price pressures and net profit in the first-quarter rose 5 percent to $685 million. "We saw improved profitability in several businesses compared to the end of last year and we intend to build on that momentum to tap the many opportunities we see for profitable growth over the rest of the year," Hogan said in a statement. Margins came under pressure in ABB's power businesses, which has faced aggressive price competition from Asian peers. Rival Siemens (SIEGn.DE) said on Wednesday it may revamp its power transmission arm as it grapples with tough competition in the market for transformers and switch gears. ABB reiterated it expects sales in its early-cycle businesses, which make products ranging from industrial robots to software, to grow at low single-digit percentage rates compared with 2011 levels until economic confidence improves. In its later-cycle businesses, which produce power transformers for utilities, it expects a strong order backlog to propel growth at a high single-digit percentage rate. French rival Schneider (SCHN.PA) said last week organic sales would inch higher at best in 2012, hit by a slowdown in Asia and austerity measures in Europe. Hogan said ABB was seeing good order activity in offshore wind power, contrasting with Siemens which slashed its full-year outlook after incurring a charge related to delayed offshore wind power projects in the second quarter.
Astra Resources Plc: MoU signed with China Railway, view to production across resource suiteInternational diversified resource company, Astra Resources PLC (FWB Code: 9AR), has signed a Memorandum of Understanding (MOU) with China Railway (Beijing) Vehicles Equipment Co. Ltd (CRVE) relating directly to the commencement of production across Astra’s vast resource suite. The MOU also reflects CRVE’s desire to build a long-lasting relationship with a global resource and technology company, such as Astra and support the immediate and future infrastructure (mining equipment) and finance solution requirements of Astra and to begin full scale production for Astra’s Company owned mines. Further, CRVE will purchase specific resources, including thermal coal and iron ore, from Astra for its significant rail production and infrastructure projects in addition to its massive power generation requirements and close association with China Power. Astra CEO Dr Jaydeep Biswas says this is a significant step forward for the company in the wake of its recent announcement regarding the geological investigation and feasibility study into its Nigerian thermal coal sites and deposits and the recent favourable report from the Cagayan River Construction & Development Corporation (CRCDC) on its Philippine iron sands project. “Entering into both formal discussions and contracts with major resource players and buyers, such as CRVE, not only secures long term revenue streams, but also opens the door for further discussions and agreements with regards to our project financing needs and production of Astra’s other major resource assets of iron ore and thermal coal and the imminent commercialisation of the clean coal conversion technology,” Dr Biswas says. “China represents the biggest resource buying market in the world and Astra are now well positioned to take full advantage of this by entering into this MOU with one of the largest State Owned Agencies (SOA) in China that has a huge appetite for thermal coal and iron ore supply and connection to many of China’s SOA’s.” The ground breaking MOU was facilitated by Senior China Advisor, Stephane Muller-Margot who says China’s thermal coal and iron ore needs are immense and during this stage of massive development and urbanisation it is vital that we identify and partner with major resource companies like Astra to ensure a consistent, and secure, supply chain. “This is the first step in developing a significant relationship with Astra following the signing of a letter of intent (LOI) in January 2012 and to provide all of the necessary project infrastructure and financial support for the various assets that CRVE wishes to lock up for future sales offtake agreements,” Mr Muller-Margot says. Astra is also in meaningful discussions and negotiations for an extension to this MOU with other Chinese SOA’s to utilise Astra’s Clean Coal Conversion Technology, Gold assets throughout Asia, Agricultural Resources and the production of the company’s ground breaking T-Steel steel technology.

Atlas Iron plans to boost output to feed China growthThe Perth-based miner today released its quarterly results, which showed that despite a tough quarter, it was on track to ship up to 5.7 million tonnes of iron ore this financial year. The report comes after the Pilbara miner announced this week that in joint venture with QR National it was studying the development of a new, multi-user railway to transport ore from the central and south east Pilbara to Port Hedland Port. Atlas managing director Ken Brinsden said despite the deal with QR, the company was still free to talk with other parties about access to existing railway. "At Atlas we have always taken pride in having options for development in front of us," he said. The company's results, released today, revealed a a 13 per cent quarter-on-quarter fall in shipments for the three months to 1.2 million tonnes. Despite the fall in shipments, Atlas said it still expected operating costs of between $42 and $45 a tonne. "We shipped 1.2 million tonnes in what I would describe being a tough quarter," Mr Brinsden said. "We were impacted by a cyclone in January, associated wet weather and we were also impacted by some outages on the Utah Port ship loader. January was pretty ordinary from our point of view ... but importantly in February and March, Atlas hit its straps and was essentially back on target for a 1.5 million tonne per quarter run rate." Atlas outlined that it planned to invest a further $630 million to develop its mining operations to ramp up its export rate to 12 million tonnes a year by the end of 2013. Whitehaven Coal also released its quarterly results today, outlining that its sales increased in the January-March quarter despite exceptionally wet weather in the first two months of 2012. Coal sales rose 6 per cent quarter-on-quarter to 1.42 million tonnes, including 1.06 million tonnes produced at its mines and 357,000 tonnes of purchased coal. Sales for the first nine months of the financial year that ends June 30 were 1 per cent lower at 4.71 million.

Importance of short-wavelength excitation in environmental vibrations due to urban rail trafficEnvironmental vibrations induced by urban railway traffic are mainly generated from uneven wheel–rail contact in the short wavelength range, according to a study in the 4th issue of SCIENCE CHINA Technological Sciences, 2012. The introduction of urban railways is one of the most effective ways to deal with traffic problems in large cities. However, in the vicinity of railways, day-by-day vibrations from trains may cause discomfort to people, the malfunctioning of sensitive equipment, and even damage to old buildings, and railways therefore have serious environmental problems. The development of urban railways is now limited by such environmental vibrations. Effective vibration-reduction technologies rely on a good understanding of the excitation source that generates the vibrations. "In recent years, substantial progress has been made in modeling the train–track–ground interaction, and consensus has been reached that the excitation source is the moving of constant loads and uneven contact between wheels and rails," according to background information in the article. "Nevertheless, the contact can hardly be measured directively, so its amplitude and frequency contents are not completely understood, and its quantitative expression remains a problem for further research to address. Recently, a research group led by Prof. Tao Xiaxin at Harbin Institute of Technology, China, has made a breakthrough in revealing the excitation mechanism. Based on an inversion study in the frequency and wave-number domain, Dr. Wang Futong, a key research member in the group, has found that high-frequency contents are predominant in the excitation. A power spectral density function (PSD) of uneven wheel–rail contact, rather than the track PSD, was suggested to describe the random characteristics of the excitation source. An inversion strategy was then established to obtain the source function from vibration data recorded by an observation array at the ground surface. The wheel–rail unevenness PSD, being the source function for the No. 13 Beijing urban railway, was obtained by the inversion strategy. The result indicated that the source function properly described the track unevenness in the range of wavelengths over 1.2 m, and showed wheel irregularities in the range of wavelengths shorter than 1.2 m. The researchers found that, in the range of short wavelengths under 1.2 m, the wheel–rail PSD maintained a value higher than the 6th class of the track PSD suggested by the Federal Railway Administration. As urban trains do not travel particularly quickly, this short wavelength range exactly corresponds to the main frequency band of environmental vibrations; i.e., the frequency components of the vibrations stem mainly from that range of uneven excitation. Taking account of only moving constant loads and track unevenness could result in a severe underestimation of the environmental vibrations. "Whereas the track spectrum reflects only the evenness of the track, the wheel–rail spectrum expresses both the track unevenness and the irregularities of wheels, and it is therefore more suitable to be used as the source function of urban railway traffic," the researchers write. "It is also shown that inversion of the exciting source according to observed ground vibrations is an effective way to detect quantitatively the combined wheel–rail unevenness."

Deputy minister: Chinese companies to work on Qazvin-Rasht-Astara railwayCompanies from China will be conducting work on the Qazvin-Rasht-Astara railway, which is a priority for Iran right now, Iranian Deputy minister of roads and city planning Ahmad Sadeghi said, ISNA reported. The railroad would begin in Iran's Hormuzgan port of Khuzestan province, forward to Iran's center of Gazvin, then to Bender-Enzeli port, and to Amirabad port. Sadeghi also noted that aside from Chinese, other foreign companies are currently working on railway's construction. Qazvin-Rasht-Astara railway is a part of the North-South transport corridor implemented by Azerbaijan, Russia and Iran. Investments worth $400 million have been made in the construction of the railway. Investments were planned to be drawn at the expense of banks of project member countries, as well as from other regional financial institutions. During the preliminary years the volume of freight transportation via the railway is projected at six million tons a year, with a subsequent increase in the volume of freight to 20 million tons per year.
China to supply $1.9m emergency bridgesA CONTRACT has been signed between the China Railway First Group and the Works and Transport Ministry for the supply of four Bailey bridges over the next three months to be used during emergencies. A deal was signed between ministry permanent secretary Commander Francis Kean and executives of the Chinese company for the supply of four spans which are estimated to be worth more than $1.9million. A government statement said initially it had been planned to bring in the bridges as a temporary crossing for the broken Moto bridge in Ba, however, because of the time factor the plan was shelved. The Heavy Compact HD 200 Portable Steel Bridge is a prefabricated bridge composed of three-metre panels that can allow vehicles to cross. Each bridge span is 51 metres long and can accommodate a maximum load of 30 tonnes. The bridge components will be kept in a storage facility and assembled when the need arises. The Moto bridge was damaged during the recent floods. |
