Service between Queenstown and Outram Park resumes after train fault; 2nd disruption of the day following Circle Line signal fault
Train services were stopped between Queenstown and Outram Park stations on Wednesday (Nov 2) evening. Published 1 hour ago Christopher Tan Senior Transport Correspondent Chew Hui Min SINGAPORE - Even as rail operator SMRT struggles to deal with a mysterious glitch which affected the Circle Line in the morning on Wednesday (Nov 2), service on its East-West Line lapsed during the evening peak. SMRT tweeted at around 5.45pm that there is no service between Queenstown and Outram Park stations because of a train fault at Tiong Bahru station. It added that it expects to remove the stalled train at around 6.10pm. Free regular bus services are available between Queenstown and Outram Park, SMRT said in a separate tweet. Train service resumed at about 6.20pm. Trains were "progressively" returning to normal speed, SMRT said. This was the second disruption to SMRT train services in a day. An "intermittent" signal fault caused the disruption of train service from about 7.30am on Wednesday. At around 9.10am, SMRT announced that there was no train service between Botanic Gardens and Marymount stations on the Circle Line in both directions. continue reading here : http://www.straitstimes.com/singapor...train-fault-on Why nobody dare to sack Desmond Kuek ???

Re: 2 young lives lost
I bet they will form a committee to investigate what happen. Such a small area still cannot solve the problem ? What the LTA & SMRT engineers are doing ? Again let me give some suggestion maybe they should change the receiving signal frequency of the train . Or they should just put a train driver in charge . Are those driverless trains really that safe to travel on ?

Mysterious signal fault hits Circle Line again
Published 6 hours ago Disruption affects thousands of commuters during morning crush Christopher Tan Senior Transport Correspondent The mysterious signal interference which interrupted service on the Circle Line MRT two months ago is back. Thousands of commuters were affected during the morning crush yesterday when an "intermittent signal fault" persisted for three hours from around 7.30am. At one point, service ground to a halt for more than an hour in the northern stretch of the line, affecting five stations between Botanic Gardens and Serangoon. On other parts, journeys were delayed by 20 to 30 minutes up to past 10am. The disruption had a ripple effect as stranded commuters took to taxis and private transport, adding to peak-hour traffic on the road. Motorist Chester Chong said he took an hour and 20 minutes to get from Teban Gardens to Bartley, a journey which usually takes 45 minutes or less. "I was stuck on the PIE (Pan-Island Expressway) for 45 to 50 minutes," the 31-year-old sales consultant said. "When I reached the Braddell flyover, I could see a huge jam in the other direction." SMRT said that preliminary findings revealed a communications glitch similar to the one which disrupted service on the line for a week in late August. The first incident was traced to an unknown signal interference which disappeared as mysteriously as it appeared - before the source could be established. In a joint statement yesterday, SMRT and the Land Transport Authority said they had arranged with the Infocomm Media Development Authority and mobile network operators "to suspend telecommunication signals along stretches of the line for short periods of time to assist in investigations". This is to establish whether telco signals are behind the interference. They also said the driverless Circle Line trains "will be manned during evening peak hours". SIM University senior lecturer Park Byung Joon said: "They have to find the source of this interference. The system is not a living organism. It won't heal itself. So unless they find the fault and fix it, it will remain." Meanwhile, many commuters reached their destinations far later than usual. IT consultant Davis Li, 32, was stuck in a train for an hour and 45 minutes when it stalled between Caldecott and Marymount stations. "I got on at 8.15am, and the train started to move again only at 10am," he said. He reached his workplace in Bishan at 10.30am - 90 minutes late. Undergraduate Denise Tan, 21, said she was late for class despite spending $33 on a cab which she managed to secure after 20 minutes. She usually takes the train from Bartley to Kent Ridge station. continue reading here : http://www.straitstimes.com/singapor...cle-line-again Commuters no need to complain just go and sue the SMRT .

Re: 2 young lives lost
Persistent signal issue worrying and a bad sign: Experts
Authorities shutting down telco services from time to time to try and find source of interference By Kenneth Cheng Published: 4:00 AM, November 3, 2016 Updated: 11:14 AM, November 3, 2016 SINGAPORE — While the authorities and rail operator SMRT have announced steps to try to solve the bewildering signal fault on the Circle Line (CCL) — including manning the trains during evening peak hours yesterday — these are not permanent solutions and nipping the interference at the source is still key, experts said yesterday. The intermittent signal interference that triggered delays on the 30-station line from Aug 29 to Sept 2 returned during the morning rush-hour yesterday, crippling services at six stations. The fact that the source of the faults continues to elude the authorities and SMRT is “a pretty bad sign”, said Professor Lim Teng Joon, a wireless-communications expert at the National University of Singapore. Singapore Institute of Technology railway signalling control and communications lecturer Andrew Ng said the fact that the problem has persisted for so long suggested that “a combination of sources” could be behind the interferences. If this is so, Prof Lim said it would be “a very sophisticated attack” and could point to transmitters being placed at several points along the line. Detecting the source is nevertheless “extremely difficult”, he acknowledged. Since electromagnetic waves generated by various sources are bouncing off all the walls, “even if you could somehow detect (their) arrival, it doesn’t indicate the direction of the source of the signals”, Prof Lim said, adding that the signals may not be on long enough to be detected. For now, the only fail-safe solution is to drive the trains manually on the driverless CCL, the two experts said. Doing so obviates the need for the system to rely on electronic signalling, which typically controls a train’s speed and the distance between trains, Prof Lim said. Agreeing, Assistant Professor Ng noted that the current set-up means that the CCL is heavily reliant on wireless communications between trains and tracks. continue reading here : http://www.todayonline.com/singapore...d-sign-experts

Re: 2 young lives lost
Signal glitch on Circle Line continues, delays expected on Thursday evening
Published 58 min ago Christopher Tan Senior Transport Correspondent SINGAPORE - Rail operator SMRT warned that there may be delays on the Circle Line (CCL) on Thursday evening (Nov 3) because of an unresolved signal interference. It tweeted at 6.07pm, saying: "Due to intermittent signal interference, CCL trains may experience delays. "For safety, CCL trains are manned this evening. We are sorry." The unknown interference resurfaced on Wednesday morning (Nov 2), after a two-month reprieve. It first appeared in late-August, and crippled Circle Line service for about a week. It disappeared as suddenly and as mysteriously as it appeared, and engineers were not able to trace its source. SMRT suspects it may have to do with telecommunications cables in the tunnels, but despite having roped in the Infocomm Media Development Authority and mobile network operators to help, it could not resolve the issue. The stray signal interferes with the wireless signal communication between the trains and the tracks, causing the trains to apply emergency braking. continue reading here : http://www.straitstimes.com/singapor...ursday-evening For safety reasons please do not take CCL . Boycott SMRT .

Circle Line signal woes: What we know so far
What is the issue plaguing the rail network run by SMRT, and what are SMRT and LTA doing to address the root issue of the signalling woes said to be causing the service disruptions? Posted 03 Nov 2016 17:15 Updated 03 Nov 2016 19:23 SINGAPORE: Commuters in Singapore experienced another service disruption on the Circle Line on Wednesday (Nov 2), with operator SMRT and the Land Transport Authority (LTA) stating that “intermittent signal interference” was the cause of the three-hour long episode. In a tweet on Thursday, SMRT said due to intermittent signal interference, Circle Line trains may experience delays. "For safety, CCL trains are manned this evening. We are sorry," it said. Services were disrupted between Botanic Gardens and Serangoon stations, after one train stalled in the direction of Dhoby Ghaut. Other parts of the Circle Line were also hit by delays after trains travelled at a slower speed due to the signalling issue. LTA and SMRT indicated in their statement on Wednesday that the nature of the faults could be similar to those that plagued the line earlier in September, when train services were repeatedly delayed on five consecutive days due to signalling issues. So what is the issue at hand, and what are LTA and SMRT doing to get to the root of the issue and prevent future such occurrences? WHAT IS THE RAIL SYSTEM USED? LTA awarded the contract to French manufacturer Alstom in 2000 to have its Alstom Metropolis C830 trains ply the Circle Line. For its signalling requirements, the trains and controls use the Urbalis communication-based train control (CBTC) rolling stock, which is similar to those used in the North East Line (NEL), but powered by a third rail instead of an overhead power source. According to an Alstom, the Urbalis CBTC “gives operators precise control in the movement of their trains, allowing more trains to run on the line at higher frequencies and speeds in total safety – with or without drivers”. continue reading here : http://www.channelnewsasia.com/news/...r/3258482.html
