More planned MRT line closures as network ages and requires more maintenance: Jeffrey Siow
The current 3.5-hour nightly maintenance window is insufficient for major works, says Acting Transport Minister Jeffrey Siow, following recommendations from a rail reliability task force.

SINGAPORE: Commuters should expect more planned closures of MRT lines as Singapore's rail network ages and requires extended maintenance time for major upgrades, Acting Minister for Transport Jeffrey Siow said on Wednesday (Nov 19).

Speaking at the International Metro Operators’ Summit at Marina Bay Sands, Mr Siow said Singapore has so far limited maintenance hours to prioritise train operations for commuters.

“But as our network ages, we have to shift this balance a little bit, to create more time for major upgrades that require a continuous block of maintenance time,” he said.

Currently, most maintenance work is carried out within a 3.5-hour window each night – from the end of train services to their resumption in the morning. After accounting for the time needed to deploy and extract heavy equipment, maintenance teams have only about two hours of actual working time.

“This is scarcely enough time to get the system ready for the next morning, let alone do any major upgrades,” Mr Siow said.

The current approach of slightly extending maintenance hours – by ending services earlier and starting later – is no longer enough, he added.

“We have to begin planning for longer scheduled closures. This will enable repair works to be completed much faster, and just as importantly, it will also be safer for transport workers.”

Mr Siow’s remarks follow recommendations from the recently formed rail reliability task force, which called for longer scheduled closures on parts of the network to improve reliability.

One example is the upcoming closure of segments along the East-West Line from Nov 29 to Dec 8, to connect the line to the new East Coast Integrated Depot. Alternative bus and train options will be available, though journey times will be longer.

“I ask for commuters’ understanding, so we can do the necessary maintenance and repair works, and reap the reliability dividend,” Mr Siow said.

TECHNOLOGY, MANPOWER CHALLENGES
Beyond scheduling constraints, Mr Siow highlighted other hurdles in maintaining and upgrading the rail system.

One is the slow pace of technological advancement in public transport. While metro systems are typically state-of-the-art when first opened, they soon become outdated.

“Technology moves very quickly, but legacy systems cannot be upgraded easily,” he said.

Although sensors that track real-time performance have become cheaper, retrofitting older systems to collect such data remains difficult and costly. Many maintenance tasks also remain manual, such as tunnel inspections.

Mr Siow noted that operators are developing new technological tools: SBS Transit is working on a robotic dog to inspect trains for faults, while SMRT has automated its Bishan depot using rail-guided vehicles and advanced equipment.

“But I think much more can be done in this area,” he said.

Another challenge is the shortage of new talent. Rail maintenance jobs are physically demanding, making it difficult to draw in younger workers, he said.

At the same time, newer metro systems require highly specialised technical skills in electrical, mechanical and systems engineering, where competition for talent is intense.

Institutions such as the Singapore Rail Academy and National Transport Academy, along with initiatives like the SGRail Industry Scholarship, aim to nurture the next generation of rail professionals.

Mr Siow added that part of a S$1 billion (US$767 million) fund set aside for rail maintenance will support manpower development.

“All these efforts will take some time to bear fruit, but I believe we will have better manpower outcomes in the coming years,” he said.

KLIA aerotrain needs complete reset, says transport expert

PETALING JAYA: A month-long action plan to fix the Kuala Lumpur International Airport (KLIA) aerotrain of its systemic disruptions does not guarantee a long-term solution.

Feasibility and systemic issues require more than a month for review, while the whole system needs a reset, says a transport expert.

For the action plan to work, Malaysia Airports Holdings Bhd (MAHB) should “reset” the new aerotrain system, instead of continuing with the old system, said Assoc Prof Dr Law Teik Hua from the Engineering Faculty of Universiti Putra Malaysia.

He warned if the action plan failed, KLIA would become a “technologically advanced but operationally sub-standard” airport.

“The aerotrain operators have already invested in a large-scale replacement programme of the system worth RM456mil, involving the adoption of Alstom Innovia APM trains and a communications-based train control (CBTC) system.

“The various Innovia systems developed by Alstom have been extensively used at several airports, including Dubai, Heathrow, and Jeddah Airport. If correctly implemented with the installation, integration and maintenance of the system, there will be high reliability,” said Law.

He said the recurring disruptions may “indicate systemic issues because various systems are incorporated into the project”.

“People-mover systems tend to be complex and could experience catastrophic failures if issues related to signalling, power distribution, vehicles, software and even sensor alignment are not perfected.”

He said the Dubai International Airport is also using the Innovia solutions.

“It is operating with incredible success and high levels of system uptime, with a level of performance of over 99.87% and over millions of kilometres of service life.”

“The SkyLine people-mover at Frankfurt Airport, which is widely regarded as the best people-mover system in the world, uses similar APM technologies.

“This is also true of Changi Airport’s Skytrain in Singapore, the Hong Kong International Airport’s automatic people-mover system, and the Plane Train people-mover system found within the Atlanta Airport,” said Law.

He said KLIA’s global ranking will finally depend not on the system but on its performance and the level of its maintenance, and whether the issue of flaws is treated seriously.

“If the action plan to put the aerotrain right is implemented successfully, KLIA will be able to enter the level of reputable airports and people movers,” said Law.

Besides KLIA, other airports with an “aerotrain” system include Washington Dulles International Airport, which has an automated people mover also referred to as AeroTrain and the Mexico City International Airport’s Aerotren.
