The 40 tonne axleload will come

first_imgbut track and train need common management’CONSIDER a new heavy haul railway with 40 tonne axleloads and high adhesion locos hauling frequent trains at 120 km/h, and suppose it damages your business. What are you going to say to your business manager?’ This warning from Harry Tournay of Spoornet was issued to nearly 400 engineers and specialists in the heavy haul freight business at the Sixth International Heavy Haul Conference held in Cape Town on April 6-10. Delegates had spent three days deliberating on engineering advances that would allow them to haul more tonnes at lower cost. While the iron ore market has recovered from the slump of the mid-1980s, thanks in part to rising steel demand in China and other booming Asian economies, Ben Alberts of South Africa’s Iron & Steel group ISCOR said that ’the price in real terms is in constant decline’.It was against this background that Spoornet Chief Executive Braam le Roux reminded delegates that the IHHA ’was not a very natural partnership because the customers are international competitors’. How refreshing then, that IHHA members are still willing to share their expertise in the unending search for the ideal wheel-rail interface where wear is controlled to the practical minimum. Much progress has already been made – in the last 10 years, according to the IHHA’s first chairman Dr Bill Harris, rail life has been extended from 600 million to 2 billion gross tonnes. All heavy haul railways stand to benefit from the unique fund of knowledge and research that exists within the IHHA, as do other railways with lower tonnages who experience the same wear problems over longer timescales.Le Roux urged delegates ’to push the limits beyond those which enable sound sleep’. This will require the courage to exploit advanced technologies, which could include automated train health checking, ’smart’ trains with on-board rolling stock monitoring and perhaps crewless operation, optic fibre rail integrity checking, and ground penetrating radar to ensure the subgrade is in good fettle. Perhaps the biggest challenge is to go beyond the 38 tonne axleload limit already being contemplated by BHP in Australia’s Pilbara, with 40 tonnes and beyond forming the quantum leap that Tournay saw as missing in topics up for debate at the conference.In contemplating the advance beyond current axleload limits, Harris warned that it was ’imperative to treat the railway as a system’ and cited the cost in terms of track wear in North America in the 1970s after many railroads introduced so-called 100 ton cars (loaded weight 119·3 tonnes) – ’it wasn’t long before the subgrade let us know that it wasn’t very happy’. Outgoing IHHA Chairman John Reoch considered separation of operations from infrastructure to be ’fundamentally flawed’, a view supported by Roy Allen, Vice President, Research & Test, at the AAR who pointed to rail grinding that had contributed to a spate of derailments affecting double-stack trains.It will be instructive to see how aspiring IHHA members in Sweden (operator MTAB and infrastructure authority Banverket) handle the planned upgrade to 30 tonne axleloads on the Luleå – Kiruna – Narvik line; the price of getting it wrong could be high. To find out what transpires, rendez-vous in Russia in 1999 for the IHHA’s next specialist technical session on the wheel-rail interface. olast_img read more

Cricket News Peter Siddle, Usman Khawaja and Nathan Lyon included in Australia side for India ODI series

first_imgNew Delhi: The ICC Cricket World Cup in England is just five months away but it seems Australia, the five-time and defending champions have decided that this is the time for a total overhaul in their ODI side. The squad picked in the three-match series against India has included some surprise picks and omissions. The squad sees the return of Peter Siddle, who last played an ODI against Sri Lanka in Sydney in 2010, along with Nathan Lyon and Usman Khawaja. Lyon, who is primarily Australia’s gun bowler in Tests, has played just 15 ODIs and last played in the format during the series in England in which Australia were whitewashed 5-0.The likes of D’Arcy Short, Ben McDermott, Ashton Agar and Chris Lynn have all been dropped while the fast bowling trio of Mitchell Starc, Pat Cummins and Josh Hazlewood has all been rested. In a statement released by Cricket Australia, chairman of selectors Trevor Hohns said key players had not capitalised on their chances. “Travis Head, D’Arcy Short and Chris Lynn have had opportunities to cement their spots, but unfortunately, they have not been as productive as we would have liked in recent times when playing ODI cricket for Australia. With a focus on improving our ability to post competitive totals we’ve recalled Usman Khawaja, Peter Handscomb and Mitch Marsh to the squad. Usman is a batsman we know can put vital runs on the board at the top of the order, and Peter is not only a fine player of spin bowling, he’s also a batsman we know can hold an innings together while keeping the scoreboard ticking over,” Hohns said.Read More | Virat Kohli booed in Sydney Test, Ricky Ponting calls it an ‘absolute disgrace’Siddle played in the Domestic One-Day competition and managed to take nine wickets in seven games for Victoria. Khawaja has not played ODIs for Australia since the series against Pakistan. The dropping of Lynn has evoked mixed response. The Queensland right-hander failed in the series against South Africa, managing scores of 15,44 and 0. However, in the Big Bash League, he blasted 84 for the Brisbane Heat against the Sydney Sixers at the Carrara Oval. Short has underperformed in four ODIs while in the Twenty20 series against South Africa, he did not gain much success.Read More | Pujara slams third ton in series, gives India decisive advantageThe heavy workload of Cummins, Hazlewood and Starc in the Test series against India sees them getting rested for the ODIs but Australia have suffered a jolt with Nathan Coulter-Nile, their other pace option, being rested after complaining of back soreness in the Big Bash League for Perth Scorchers.Australia play three ODIs against India, starting on January 12, with the remaining matches being played on January 15 and January 18. Following the end of the ODI series, Australia play Sri Lanka and then could embark on ODI tours to India and the UAE against Pakistan. The series against Pakistan could see the return of David Warner and Steve Smith following the end of their one-year ban imposed on them following the ball-tampering scandal in Cape Town.Australia squad for India ODI seriesAaron Finch (c), Jason Behrendorff, Alex Carey (wk), Peter Handscomb, Usman Khawaja, Nathan Lyon, Mitch Marsh, Shaun Marsh, Glenn Maxwell, Jhye Richardson, Peter Siddle, Billy Stanlake, Marcus Stoinis, Adam Zampa For all the Latest Sports News News, Cricket News News, Download News Nation Android and iOS Mobile Apps.last_img read more
