SINGAPORE — A track fault at Clementi on Thursday morning (Jan 19) caused long delays along the East-West Line towards the city, with many commuters complaining on Twitter about under-reporting by SMRT.
The track fault first began at around 7.46am, according to the train operator’s Twitter account.
While train services were still available, SMRT warned passengers of an additional 10 minutes in travel time from Joo Koon to Clementi towards Pasir Ris.
At 8.01am, SMRT tweeted again that the delay had extended to 15 minutes; and by 8.25am, the additional travel time stretched to 20 minutes

Updated 19 Jan 2017 22:24
SINGAPORE: Flash floods hit Upper Thomson Road after heavy rain on Thursday afternoon (Jan 19).
National water agency PUB first issued an alert at 3.44pm, informing the public of flash floods at the junction of Upper Thomson Road and Jalan Lembah Thomson. It added that one lane was affected.
This is the same area which was flooded with knee-deep water on Christmas Eve.
According to alerts sent out by the Land Transport Authority (LTA), the flash floods also affected the direction towards the Seletar Expressway after Jalan Pelatina, with congestion until MacRitchie Viaduct.
PUB later issued another alert at about 4pm, saying the flash floods have subsided.

SINGAPORE: Trains on the North-South and East-West Lines (NSEWL) will run faster with speed restrictions being lifted after the completion of the sleeper replacement project on Friday (Jan 20).
Since August 2013, the Land Transport Authority (LTA) and operator SMRT have been replacing ageing wooden sleepers on the lines with longer-lasting concrete ones.
The replacement project is part of multi-year rail renewal efforts to increase train reliability on the NSEWL - Singapore’s oldest, longest and most heavily utilised rail line.
Currently, parts of the lines with newly replaced sleepers are limited to a speed of between 40kmh and 60kmh for safety reasons.
With the completion of the project, these speed restrictions will be lifted in phases on the lines, with all train lines to return to normal speeds of up to 80kmh by March, said SMRT Trains managing director Lee Ling Wee.
The last of the 92,000 sleepers on the East-West Line was laid on Dec 20 last year, said train operator SMRT and LTA in a joint release.
The replacement of the 96,000 sleepers on the North-South Line (NSL) was completed in April 2015.
LTA’s deputy chief executive of infrastructure and development Chua Chong Kheng said that the sleeper replacement project was just one of many efforts to boost the NSEWL’s performance.
“In the coming months, we will also see the completion of re-signalling works on the NSL and the third rail replacement project … coupled with more rigorous maintenance regimes by the operators,” he said.

That is very good . But if there is still service disruptions so how ?
Steps taken to curb flooding at Upper Thomson Road

SINGAPORE — Sato Kogyo, the construction firm whose unauthorised work on the public drainage system contributed to flash floods along Upper Thomson Road on Christmas Eve last year, has changed drain covers to open ones to facilitate the flow of water and has used sandbags to prevent water from flowing into shophouses.
Providing an update after a flash flood struck the area on Thursday (Jan 19), national water agency PUB and the Land Transport Authority said the measures were “temporary improvement works to increase the drainage capacity in the area” since the Dec 24 incident. The sandbags are placed at the edge of the five-foot ways that front the shops along Upper Thomson Road.
Earlier this week, PUB announced that it had discovered unauthorised work on the public drainage system by Sato Kogyo, which is the LTA’s contractor for the Upper Thomson MRT Station project.
Sato Kogyo had constructed an under-sized temporary diversion drain within its worksite, and had not informed PUB before it started the work. The contractor had also altered the public drainage system across Upper Thomson Road, near Lorong Mega, without PUB’s approval and faces sanctions under the Sewerage and Drainage Act.
As intense rain fell over central Singapore on Thursday, a flash flood occurred at the junction of Upper Thomson Road and Jalan Lembah Thomson for about 20 minutes, from 3.44pm to 4.05pm. The Government agencies said 59.2mm of rainfall was recorded at Lower Peirce Reservoir from 3.10pm to 4pm.
But unlike the knee-deep waters on Dec 24 that damaged the equipment of shops such as The Roti Prata House, shophouses nearby were not affected this time.

NSL to implement upgraded signalling system from March
Published: 4:00 AM, January 21, 2017
SINGAPORE — The Land Transport Authority (LTA) will be transiting to an upgraded signalling system on the North-South Line (NSL) in stages from March.
The new system will allow trains to run closer together, which means that during peak hours, they will arrive within 100 seconds of each other instead of the present 120 seconds — thus making for less congestion at the stations and a faster journey for passengers.
It is also equipped with features that provide greater redundancies in the event of signal faults. This will enhance rail reliability since critical components are duplicated as a form of back-up.
“We will begin operationalising the new signalling system during off-peak periods, when there is lower ridership, such as the last hour of train service and on Sundays, before operationalising it during busier periods,” the LTA said yesterday.
Re-signalling works on the trains, stations, depots and the operations control centre for the NSL were completed last year, but the LTA will be conducting more than 1,300 tests before putting the upgraded system into operation.
The tests include simulations to ensure that the new system responds quickly and effectively to unexpected conditions, such as loss of communication signals.

Track circuit faults unrelated to sleeper replacement works: SMRT
Posted 29 Jan 2017 08:00
Updated 29 Jan 2017 12:38
SINGAPORE: Track circuit faults which caused disruptions on the East-West MRT Line in recent weeks are unrelated to the sleeper replacement project on the North-South and East-West Lines which wrapped up in December, SMRT said in a blog post on Sunday (Jan 29).
“The track circuit system is part of the signalling system, and is not part of the sleeper infrastructure that supports the running rails which trains travel on,” SMRT explained. Track circuits send signals to the operations control centre to monitor speed, location and the identity of trains that are passing through.
When a track circuit fails, trains have to slow down over an affected stretch for safety reasons and this could cause congestion during peak hours. Because MRT trains must maintain a safe distance between one another, they could end up starting and stopping momentarily on the track.
SMRT said there are two reasons why track circuits fail:
- A hardware failure in the Signal Equipment Room within an MRT station
- Trackside circuit faults that engineers could take time to access especially in thunderstorm conditions when the track is above ground
Engineering staff must rule out a case of Signal Equipment Room malfunction before they investigate trackside faults, so it takes a longer time to recover service when equipment along the track fails, SMRT said.
“In the new signalling system that is currently being installed, the ageing track circuits will be replaced with a more advanced system that is more reliable as it is built with multiple redundancy for greater reliability. After we renew the signalling system, faulty track circuits will no longer cause prolonged delays for commuters. This is something we are looking forward to,” the public transport operator added.

Expect longer commute this evening from Jurong East to Joo Koon: SMRT
Published: 1:36 PM, February 7, 2017
Updated: 2:27 PM, February 7, 2017
SINGAPORE – Commuters should prepare for a slightly longer commute on the East-West line from Jurong East to Joo Koon on Tuesday evening (Feb 7).
This is due to the “urgent works” to replace a track point, which guides the direction of train travel, near Joo Koon Station, which began on Monday night, said SMRT in a post on Facebook.
“Due to the short work window available each night, this typically takes two to three nights to complete and is normally planned to take place over a weekend to minimise the impact to commuters on weekdays,” SMRT wrote.
However, in this case, the transport operator decided to carry out the work outside of the weekend window “due to its urgency and criticality”.
“As the replacement works could not be fully completed last night, we have locked the point in one direction and, as such, only one platform at Joo Koon Station is operational today,” SMRT added.

Rail network hit by 3 disruptions in a day
By Kenneth Cheng

SINGAPORE — Commuters were hit by three rail breakdowns at different parts of the island on Friday (Feb 10) — one on the North-South Line (NSL) and two on the Light Rail Transit (LRT) lines — beginning from the morning till late in the evening.
The day began with a disruption on the NSL during the morning rush hour caused by a signalling fault that developed on a train, which was later withdrawn from service.
The fault caused delays for commuters travelling between the Newton and Marina South Pier stations. The faulty train, which was travelling towards Yishun, was pulled from service after passengers alighted at the Raffles Place station, rail operator SMRT said.
In the afternoon, services on the Bukit Panjang LRT were affected by a train fault. SMRT tweeted about the disruption at 3.26pm, saying that free regular bus services were available along the line. Less than 20 minutes later, it said normal train services had resumed, after an earlier tweet said a faulty train was being “recovered”.
In the evening, services on the eastern loop of the Sengkang LRT were interrupted for about 90 minutes, due to a power fault.
Although the NSL disruption was brief, commuters expressed their unhappiness on social media. Twitter user Sharifah Sharomsah complained about being late for work, while another user, Wong Wing Seng, took a jibe at SMRT, saying it “should be in the Guinness Book of Records for the most breakdowns and delays”.
The NSL is due to transit to an upgraded signalling system in stages from next month, allowing trains to run at closer intervals. While the re-signalling works on the trains, stations, depots and the operations control centre were completed last year, the Land Transport Authority previously said it would push back the rollout in order to carry out more than 1,300 tests.
The last high-profile signalling interference reported happened on the Circle Line between August and November last year, which experienced persistent disruptions.
After months of investigation, including military experts being roped in for the probe, the cause was traced to faulty signalling hardware on a “rogue” train, which was later removed.
Commenting on Friday’s signalling fault on the NSL, experts said a single incident should not be interpreted as a sign of a major problem. They added that it was not unusual for trains to be withdrawn from service in order to resolve such faults.

Trains designed for fire safety, rail operators regularly tested: LTA
By Kenneth Lim
Posted 11 Feb 2017 20:30
Updated 11 Feb 2017 23:08
SINGAPORE: Trains on Singapore’s rail network are designed with fire safety in mind, with features to prevent the spread of fire and ensure commuter safety, the Land Transport Authority (LTA) said on Saturday (Feb 11).
This was in response to queries on fire safety measures following a train fire at Hong Kong’s Tsim Sha Tsui MTR station on Friday that injured 17 people, with two in critical condition.
Speaking to Channel NewsAsia, an LTA spokesperson said fire safety features included a “fire-retardant” train car body made with materials that delay the combustion of fuels.
Train floorings are also fire-resistant, and each train is equipped with fire and smoke detection systems as well as two fire extinguishers, LTA said, adding that the features were in line with international railway standards.
There are also ventilation fans in underground MRT stations and tunnels to extract smoke and supply fresh air in the event of a fire, the spokesperson added.
According to the LTA’s incident management code of practice, rail operators SBS Transit and SMRT are required to train their staff to ensure passenger safety during emergencies and prepare plans for such incidents.
