UK refines ERTMS business case

first_imgA PROGRESS report issued on May 19 by Britain’s Strategic Rail Authority and the new Rail Safety & Standards Board says there is now a sound business case for developing and installing the European Rail Traffic Management System across most of the 16666 km network. The capital cost (at current prices) of converting the network is now put at £2·4bn.A key assumption is that ERTMS Level 2 eliminates conventional lineside signalling as it falls due for renewal. For this reason, the latest economic evaluation compares the net present value of costs and benefits over 40 years. Using the Treasury’s 3·5% discount rate for publicly financed projects, the NPV of costs is £3·7bn and the benefits are £7·5bn, giving a cost/benefit ratio of 1:2. The most important costs are development, installation and operation of ERTMS; and additional train services to exploit the capacity increase of around 10% that it unlocks. The principal benefits are avoidance of renewing and maintaining signals; better use of engineering possessions; gains by rail users of more frequent, more reliable and less crowded services; and reduced road congestion through modal shift from road to rail.While ERTMS will also deliver the safety benefits of full ATP, the potential gain is now modest as the network-wide roll-out of Britain’s unique Train Protection & Warning System will be completed this year. This has removed the threat of regulations mandating installation of ERTMS before it is fully developed.Having abandoned ERTMS as a component of the current West Coast Main Line upgrade, the report confirms that the first route to be equipped with ERTMS by 2006 for trial purposes will be the 217 km of single track from Shrewsbury to Aberystwyth and Pwllheli in mid-Wales. This will be at Level 2, as there is no investment case for Level 1. All but 7 km of the Cambrian lines are currently controlled by Radio Electronic Token Block, due for replacement by 2008. RETB will be replaced by Level 2 System E, a simplified version of System D adopted as the British standard (RG 6.02 p314). The 7 km of track circuit block, including a simple junction with one set of points, will get System D linked to a computer-based interlocking. The North Wales Coast line to Holyhead is likely to follow by 2010, in effect as a further trial, before System D is installed on the 200 km/h Great Western main line from London to Bristol and South Wales, replacing a pilot ATP system installed in the early 1990s. SRA Chairman Richard Bowker said ’what is likely to be the case is that by the target of 2015 you are looking at rollout across all three’ EC-designated high speed routes, covering the East and West Coast main lines as well as the GWML.last_img read more

Three bad habits damaging to your child’s teeth

first_imgAs a parent, you try to do the right things for your children. In addition to regular doctor appointments and healthy lunches, make sure you are not unknowingly teaching your children poor dental hygiene.Sweets between MealsWhile a snack between meals is normal, the wrong type could lead to tooth decay. Candy and sugary juices between meals can damage teeth. Instead, stick to healthier snacks with complex carbohydrates, like fruits. If your child wants a sweet on occasion, offer it with a meal. The saliva produced to digest larger quantities of a meal helps keep teeth bacteria-free.Drinks before BedRethink your strategy if a sippy cup is part of your nightly routine. When children drink juice, chocolate milk or even milk before bed without brushing their teeth afterward, the sugar in those drinks lingers, which leads to cavities. So for bedtime drinks, stick with water. If your child has a sugary drink before bedtime, make sure they brush their teeth before going to bed.Skipping Dentist AppointmentsResearch recommends that both children and adults see a dentist every six months. Skipping a couple of appointments because your child’s teeth appear fine could prove dire. Aside from tooth decay, a typical appointment also involves preventive cleaning and dental care training. So be sure to always schedule the next appointment before you leave the dentist’s office.last_img read more

14-month-old baby girl sexually assaulted In Trinidad

first_img Share PORT OF SPAIN, Trinidad, Jan 20 2016 – Police here are investigating allegations that a 14 month old baby girl had been sexually assaulted.The Children’s Authority of Trinidad and Tobago said it is working with the Child Protection Unit of the Trinidad and Tobago Police Service “to provide support services to the baby and her family” and that it is treating the matter “with the sensitivity and confidentiality it deserves.“The Authority also commends the baby’s observant grandmother for bringing the matter to the attention of the police. Since child abuse often occurs in the home, it is important for everyone to be aware that they have a responsibility to protect children,” the Authority said in a statement.Police said on Sunday, a 20-year-old man had gotten into an argument with his 23-year-old girlfriend which became physical and the man making certain allegations, citing the woman’s behaviour as the reason he sexually assaulted the child.The Authority said that its Emergency Response Team was called out to rescue two other children who were sexually abused and that the children are now in its care and receiving the necessary support.The Authority said that it was urging people to become more aware of the signs of child abuse, and urging the population “to report any sign or suspicion of child abuse to the Police or to the Authority’s hotlines”.

51 Tahun Sejak Terbang Perdana, Inilah ‘Jejak’ Supersonik Concorde yang Selalu…,Tiga Manfaat Drone di Bandara, Nomor Dua Taruhannya Nyawa

first_imgSumber: The Christian Science Monitor 2 Maret 1969 atau 51 tahun yang lalu, merupakan momen yang sangat berharga bagi perusahaan kedirgantaraan asal Inggris (British Aircraft Corporation) – Perancis (Aerospatiale) yang berhasil menerbangkan perdana Concorde. Tidak terasa sudah 51 tahun Concorde menjadi bagian dari sejarah kedirgantaraan internasional. Memang, beberapa tahun ke belakang ini, ada sejumlah perusahaan yang berusaha untuk ‘membangkitkan’ nuansa Concorde – sebut saja Boom Technology dengan armada Mach 2.2 rancangannya, namun ada beberapa poin penting yang tidak bisa dilupakan dari nama besar Concorde.Baca Juga: Suksesor Concorde ini Tetap Dihantui Bayangan Kelam PendahulunyaBagi Anda yang rindu dan mulai sedikit lupa dengan pesawat berkecepatan supersonik ini, berikut adalah sejumlah fakta dari Concorde yang dirangkum KabarPenumpang.com dari berbagai laman sumber. Upaya Untuk Mengudara yang Tidak SingkatDi atas sudah disebutkan bahwa 2 Maret 1969 merupakan kali pertama Concorde dengan prototipe pertamanya, Concorde 001 membelah angkasa. Kala itu, langit Toulouse di Perancis menjadi saksi bisu dari terbangnya prototipe ini selama kurang lebih setengah jam lamanya. Sejak saat itu, dibutuhkan waktu sekira tujuh tahun lamanya bagi perusahaan yang dikembangkan oleh Aerospatiale (Perancis) dan British Aircraft Corporation untuk bisa memulai layanan komersialnya.Penerbangan penumpang terjadwal perdana dari Concorde ini terjadi pada 21 Januari 1976, dimana maskapai Air France menjabani rute penerbangan Paris – Rio de Janeiro, dan British Airways yang melakoni rute penerbangan London – Bahrain.Inovasi bak SiluetJika dilihat dari desainnya, apa yang sangat membedakan Concorde dengan burung besi lainnya? Jika Anda menjawab bagian moncong pesawat dan sayapnya, maka jawaban Anda tepat! Ya, beberapa ahli di sektor aviasi percaya bahwa desain moncong pesawat yang menukik ke bawah akan memungkinkan visibilitas pilot menjadi lebih baik lagi. Serta penggunaan sayap delta (penampang datar sayap berbentuk segitiga) dikabarkan mampu memberikan stabilitas dan efisiensi saat mengudara.Ya, dua inovasi yang selama ini bernaung di bawah nama besar Concorde memang termasuk ke dalam sistem aeronautika yang canggih pada jamannya – atau mungkin bahkan sampai sekarang! Jangan lupakan kecepatan jelajah Concorde yang mampu menembus angka 2.200 km/jam, ya!Thunderously NoisySudah sewajarnya mesin jet Concorde ini mengeluarkan suara yang bisa memekakkan telinga. Jika telinga manusia bisa mendengar suara dengan kekuatan 110 desibel, maka suara yang dihasilkan oleh mesin-mesin jet di pesawat Concorde tercatat menyentuh angka119,4 desibel. Siap-siap sakit telinga ya.Baca Juga: Boeing Akan Gunakan Sayap Ultra Tipis di Prototipe Pesawat TransonikHanya Ada 14 Unit SajaMisi pengembang adalah untuk menjual lebih dari 100 armada Concorde sepanjang masa kompetisinya di sektor kedirgantaraan – namun di umurnya yang ke-34 tahun terhitung sejak penerbangan perdananya, Concorde hanya berhasil dijual 14 unit saja. Tujuh armada digunakan oleh AirFrance dan sisannya dioperasikan oleh British Airways.Akhir dari ConcordeEra milenium menjadi awal-dari-akhir riwayat Concorde di sektor kedirgantaraan global. Jatuhnya Air France Concorde pada Juli tahun 2000 seolah menjadi pertanda bahwa era pesawat supersonik ini akan segera berakhir. Menewaskan total 113 penumpang dan kru, Air France dan Concorde sempat ditangguhkan – kesialan di tubuh Concorde semakin meradang.Hingga puncaknya pada tahun 2003, kedua maskapai yang menggunakan jasanya ini memutuskan untuk menghentikan penggunaan Concorde. Mei 2003, Air France melakukan penerbangan terakhirnya bersama pesawat supersonik ini, disusul oleh British Airways pada bulan Oktober di tahun yang sama.

Redam Kebisingan, Jepang Lakukan Riset Aerodinamika Kereta Cepat dengan Terowongan Angin

first_imgKereta Cepat Shinkansen, Jepang. Sumber: wikipedia Railway Technical Research Institute (RTRI) Jepang dikabarkan tengah mempelajari cara untuk mengurangi efek dari fenomena aerodinamis pada kereta berkecepatan tinggi dan infrastruktur pendukung lainnya. Seperti yang sudah diketahui bersama, Jepang merupakan negara yang bisa dibilang terdepan dalam urusan moda rel. Hal ini ditunjang dengan kehadiran Shinkansen sebagai kereta berkecepatan tinggi paling terkenal di dunia.Baca Juga: Lima Fakta Unik dari Shinkansen yang Mungkin Anda Belum Tahu!Mungkin beberapa dari Anda masih ingat bahwa aerodinamis merupakan salah satu faktor penting yang melancarkan pengoperasian dari kereta cepat ini. Jika tidak ditunjang dengan gaya aerodinamis, maka kecil kemungkinan kereta semacam Shinkansen ini bisa ngacir hingga kecepatan lebih dari 200 km per jam. Kendati begitu, namun gaya aerodinamis ini juga menimbulkan efek samping yang bisa mengganggu kenyamanan penumpang – mulai dari suara bising hingga guncangan. Sebagaimana yang dilansir KabarPenumpang.com dari laman railjournal.com, RTRI tengah melakukan penelitian dan pengembangan guna mengklarifikasi mekanisme yang menghasilkan fenomena gaya aerodinamis ini. Tidak hanya itu, RTRI juga mengevaluasi fenomena aerodinamis ini dengan menggunakan metode simulasi numerik, pengujian laboratorium hingga tes kendaraan. Belakangan,  tersiar kabar bahwa RTRI menggunakan pendekatan eksperimental guna mengusut masalah ini.Menurut RTRI, fenomena aerodinamis ini mempengaruhi struktur garis dan orang-orang yang berada di sekitaran rel. Semakin kencang kecepatan operasi kereta, maka semakin besar pula efek dari fenomena ini. Maka dari itu, pendekatan eksperimental yang dilakukan oleh RTRI adalah dengan menggunakan terowongan angin (wind tunnel) dan rig kereta model bergerak (moving model train rig).“Kami mengembangkan metode untuk uji terowongan angin untuk menyelidiki sumber suara dengan menggunakan microphone array,” ujar pihak RTRI.“Sebagai hasilnya, kami mengklarifikasi bahwa distribusi sumber suara aerodinamis ini berasal dari bogie, dan menemukan bahwa bunyi aerodinamis yang dihasilkan oleh bogie dapat dikontrol dengan mengurangi kecepatan aliran udara di dekat permukaan bagian bawah kereta atau dengan mencegah udara berkecepatan tinggi,” sambungnya.Menanggapi temuan ini, RTRI mengatakan bahwa pihaknya akan mempelajari lebih lanjut guna menemukan solusi untuk kebisingan ini.Baca Juga: Hokkaido Shinkansen, Bisa Tetap Kebut Walau di Bawah Laut“Jika kereta Shinkansen terbaru beroperasi pada kecepatan lebih dari 300 km per jam, maka kontribusi kebisingan aerodinamis akan meningkat secara signifikan,”“Kami sedang mempelajari cara-cara untuk mengurangi suara yang dihasilkan dari fenomena aerodinamis ini,” tutup RTRI.Share this:Click to share on Twitter (Opens in new window)Click to share on Facebook (Opens in new window)Like this:Like Loading… RelatedDi 2027, Jepang Hadirkan Kereta Cepat Maglev Tokyo-Nagoya19/08/2019In “Darat”Ternyata, Olimpiade 1964 Punya Pengaruh Penting Bagi Jaringan Kereta Shinkansen02/01/2019In “Darat”Mendapat Tentangan dari Oposan, Beginilah Sejarah Singkat Kereta Cepat Shinkansen10/12/2018In “Darat”last_img read more

According to the report, Napoli and the club are still discussing the possibility of the 36-year-old starting the 2018 season with Triple-A Columbus.Napoli will be released and then re-signed by Indians on Minor League deal. Just a paperwork move. He’s still discussing a possible trip to Triple-A with Cleveland, if no other MLB opps are available.— Jordan Bastian (@MLBastian) March 22, 2018The team brought Napoli on board this spring so that he could train with a club and essentially showcase his skills for other teams throughout the league as he tries to earn a roster spot. Prior to signing him, manager Terry Francona even sat down Yonder Alonso and Edwin Encarnacion to tell them Napoli wasn’t there to take their spots.But if there is not another Major League opportunity for Napoli out there, (and given the free agent market this offseason, that doesn’t seem likely) he could still provide the team some depth down in Columbus, especially if injuries occur.Napoli is an Article XX(B) free agent, meaning, per Bastian:[A] player who a) has six or more years of service; b) finished the prior season on a 40-man roster or on the 60-day DL; and c) signed a Minor League deal over the offseason — would be eligible for a $100,000 retention bonus and a June 1 opt-out clause, if he accepted a trip to the Minors. Cleveland and Napoli have to make their decision on that front by Saturday.“I’m glad we brought him,” Francona said a few days ago. “He has handled it and then some. He has been so good for us. He’s been so good for the guys and good for me and good for everybody. He’s just a special guy, man. There’s no getting around it.”last_img read more

LSU Nation Lunch: Tiger fans confident of more wins

first_imgRusty Ratcliff and wife Donna Ratcliff of St. Joseph, La., enjoy lunch at M's Pub in Old Market in Omaha Wednesday.Rusty Ratcliff and wife Donna Ratcliff of St. Joseph, La., enjoy lunch at M’s Pub in Old Market in Omaha Wednesday.OMAHA, Nebraska – Sometimes the best vacations are a tad open ended — both the daily schedule and the departure date.Such is the case of LSU baseball fans Rusty and Donna Ratcliffe of St. Joseph in northeast Louisiana – 34 miles south of Tallulah. Rusty, a cotton and corn farmer who graduated in agricultural engineering from LSU in 1978, and Donna, the tax assessor of Tensas Parish, have been in town for the College World Series since Saturday and are not sure when they are going back home.Then again, neither is LSU, which stayed alive Tuesday afternoon by eliminating Cal State Fullerton, 5-3, in the double-elimination bracket portion of the World Series at TD Ameritrade Park. The Tigers (54-11) play Texas Christian (50-14) at 7 p.m. Thursday on ESPN. TCU lost to Vanderbilt, 1-0, Tuesday night, after defeating the Tigers, 10-3, on Sunday.If LSU eliminates TCU Thursday, it will play Vanderbilt at 7 p.m. Friday on ESPN. If the Tigers win that game, it will play Vanderbilt again Saturday at a time to be announced, depending on what is happening in the other four-team bracket. Should LSU win its next three games, it will advance to the best-of-three national championship series at 7 p.m. Monday and 7 p.m. Tuesday. If a third game is necessary, that will be at 7 p.m. Wednesday.“Our plane is supposed to leave on Friday, but we might not be on it,” Rusty said. “If we win Thursday, we might be here awhile.”There was not much on the Ratcliffe’s agenda Wednesday as they sipped adult beverages over lunch at M’s Pub in Omaha’s Old Market amid a bright sun, but temperatures only in the 70s. It was in the 60s Tuesday night.“We’re very spontaneous,” Donna said. “We’re just going to see how it goes. We don’t know where we’re headed it yet. We like it like that.”This plan tends to work for meals before LSU baseball games — home or away.“We didn’t bring all our tailgating stuff,” Donna said. “But LSU fans, they take you on in.”Tiger fans will likely be in even better moods leading into Thursday night’s game as the 0-for-Omaha pressure was lifted with the win Tuesday. Before that, the Tigers had gone 0-for-2 here in 2013 and then lost their opener on Sunday.“We were here in 2013,” Donna said. “And my boss (Tensas Parish Sheriff Rickey Jones) said, ‘Don’t go. You’ll make them go 0-2 again.’”Rusty was cleared of any blame for the recent 0-for-3 because he flew solo here in 2009 when LSU won the national championship with four straight wins in bracket play before taking two out of three from Texas for the title.“We got them to the championship series. Then we left, and some friends of ours took over and took them to the championship,” Rusty said.“Yes, it’s up to us — not the team,” Donna said laughing.Rusty says the Tigers have the offense and enough pitching depth to last until next week.“Our offense is great,” he said. “You saw that Tuesday. We’ve got the momentum now, and I think we’ve got enough pitchers to last a few innings and then have some of the bullpen pitchers come in for an inning or two. We can do it.”LSU fans John and Tommie LeDoux of Sulphur and now living in Houston ate lunch at Rock Bottom brewery and restaurant on their first trip to Omaha, and they are not sure when their trip will end either.“We had planned to come two years ago, but they went 0-and-2 before we could plan to get up here,” John said. “Now, we’re sure we’ll see at least three games. Maybe more. We’re playing it by ear. We may end up staying until next week. We’re really enjoying it. We met some people from Omaha, and they invited us to their tailgating party. People are very friendly here, and we love the weather. It’s a lot like Denver (Colorado), where we used to live.”John LeDoux is one LSU fan who understands why Omaha moved the College World Series from beloved Rosenblatt Stadium – its home from 1950 through 2010 in a neighborhood – to the ultra-modern TD Ameritrade downtown.“I’d been to Omaha on business before the stadium was here, and the stadium has really revitalized the downtown area,” he said.As far as Chris Dazet of New Orleans is concerned, LSU’s victory over Cal State Fullerton Tuesday has revitalized the LSU fandom, particularly him.“I came here in 2013 with a non-refundable return flight, and they lost their first two games,” he said in the lobby of the Hyatt Place, where LSU is staying. “I was here for four solid days with no LSU games. It was the most depressing thing ever. Before LSU lost, I spent hundreds of dollars on T-Shirts and souvenirs. Then they lose, and I see this sign: ‘Elimated Teams Gear for half price.’ I could’ve bought everything I got for $50 if I would’ve waited.”Dazet is ready for more of a purple and gold Omaha this year.“Bats-wise, I think we finally woke up in the last game,” he said of the Tigers’ 13-hit attack, which was the most by LSU in a College World Series game since 2009. “When we hit, we can beat anybody.”LSU fan Ron Smith of Metairie is in Omaha for the first time.“You hear all this stuff about how friendly Omaha people are to LSU people. Then you get here, and you find out everybody is right about that. It really is true,” he said. “There was a waitress at the restaurant wearing LSU stuff. And she said, ‘I hope LSU wins.’ I just hope we can stay a few days longer.” John LeDoux and wife Tommie LeDoux of Sulphur eat lunch at Rock Bottom restaurant and brewery Wednesday. They are staying in Omaha as long as the Tigers do.John LeDoux and wife Tommie LeDoux of Sulphur eat lunch at Rock Bottom restaurant and brewery Wednesday.
