Paving the Way for Better Journeys (Jun 2016)

“Paving the Way for Better Journeys” is part of continuing efforts by SMRT to inform, update and educate commuters of the several rail renewal projects.

SMRT Better Journeys Transforming the NSEWLSuch work on SMRT’s North-South and East-West Lines (NSEWL) involve multi-year, multi-programme efforts that include changing old wooden sleepers with concrete ones, replacing signalling systems and renewing the Third Rail, as well as introducing new trains to enhance the service and reliability of the NSEWL to bring Better Journeys to all our commuters.

The key benefits from each of these efforts to commuters include Smoother Rides, Shorter Waiting Times, a More Reliable Network and More Trains (which mean higher frequency).

SMRT Trains’ Managing Director, Mr Lee Ling Wee said, “In total, there are about 200km of track on NSEWL to be renewed and upgraded. Over the past two years, we have been able to carry out these renewal and upgrade work ahead of schedule, even as we continue to keep the network operational every day. We know that the work has caused inconvenience to both commuters and residents who live near MRT track. As such, I would like to express my deepest appreciation to you for your kind understanding, patience and support.”

Keeping our cool

Air conditioning is a crucial component in keeping commuters cool on the train. Nothing irks us more than hoping to escape the humid Singapore weather by taking the train, only to find it stuffy and warm.

On all North-South and East-West Line trains, there are two air conditioning units per train car. With six cars making up a train, that’s 12 air conditioning units working keep the temperature within the train cool. There are 141 trains for the NSEWL, that’s 1,692 air con units! Excluding those undergoing maintenance on the workshop floor.

So how does SMRT maintain the air conditioning systems on the trains to help you keep cool and carry on?

Here are some top reasons for aircon failure according to a recent analysis on data collected from December 2015 to February 2016.

Blown Fuses in the aircon motor

One of the most common reasons for failure was the aircon system fuse. A blown fuse indicates excessive current which could be a result of arcing caused by the carbon dust build up inside the motor.

The source of the carbon dust is the carbon brush, a component in the aircon unit that is in contact with the aircon motor. Through normal operations, the carbon brush is wears down and carbon dust settles on the motor.

A more effective cleaning method to remove excessive carbon dust build-up has been implemented and new carbon brushes are being trialed to reduce the carbon build-up in the long run.

Defective Microcards

Microcards are like the brains of the aircon unit. When there is a defective microcard, the aircon no longer functions the way it is supposed to. In some situations, the unit fails to activate when temperatures get too high.

While replacing the defective microcards with new ones from the manufacturer is one solution, SMRT has been working on a more sustainable solution. The Integrate Electronics Workshop team at SMRT have studied the microcard and have been refurbishing defective microcards.

Leaky tubing

Freon topping up machine

The trains’ aircon units use a gas known as Freon as a refrigerant which cools the air. The Freon gas cycles within the unit in a closed system of coils. If the Freon leaks from these coils, cooling efficiency is reduced. We are stepping up efforts to plug leaks in these tubes though a process known as “brazing”.

The Freon also needs to be topped up when leaks are discovered. The use of a recovery machine ensures that the precise composition of refrigerant is used to ensure cooling efficiency.

 

 

 

Keeping an eye on things

The later models of trains on the NSEWL (KNS and KSF) are all equipped with the Trains Information Management System, or TIMS. TIMS is an entire system of sensors that measure various properties of the train during operations. The internal temperature of each car is one such property.

SMRT on board monitoring

During service, train captains can check TIMS for any aircon faults. When faults are detected, a “field team” is activated. The team will then verify the fault and where possible, rectify the issue immediately. Further inspections to the reported aircon system will also be carried out when the train returns to the depot.

SMRT CEO Desmond Kuek at HR Summit 2016

SMRT President & Group CEO Desmond Kuek gave an exclusive interview in the plenary session of the 2016 HR Summit on 17 May. The interview was facilitated by Channel NewsAsia newscaster Steve Lai, and attended by close to 1,000 participants. For the first time ever, members of the public were given the opportunity to pose questions directly to Mr Desmond Kuek and gain greater insight to the inner workings of SMRT.

Here are some highlights from the interview with Mr Kuek:

When asked about his leadership dictum, “You either lead, follow, or get out of the way – but you never stand still” and what it means to him –

Mr Kuek shared that he first adopted the leadership dictum when he was with the Singapore Armed Forces to inspire his people to take the initiative and make changes that can lead to a meaningful difference, instead of just accepting the status quo. There is always an opportunity to make a difference, whether one is leading or following another’s lead. Failing to do so would only render one increasingly irrelevant and ineffective.

He continued to apply this leadership mantra when he moved on to lead the Ministry of the Environment and Water Resources, and also currently in SMRT where we are constantly pushing the boundaries and driving for excellence.

When asked about how he ensures that staff morale is maintained amidst growing public dissent over the MRT system –

Mr Kuek confessed that there were numerous challenges and issues that had to be addressed when he first joined SMRT. The major train disruptions of December 2011 shook public confidence and dragged down the company’s reputation.  Staff morale was low, and some staff shared that they were embarrassed to wear their uniforms because of public dissent. Compounding these difficulties was the need to engage multiple stakeholders: the public and commuters, shareholders, regulators, business partners, and also SMRT’s own employees.

Against this formidable backdrop of challenges, Mr Kuek chose to place his key focus squarely on SMRT’s employees as they are the cornerstone to any improvements to be made. This meant placing a sharp focus on leading and engaging employees well, believing that this would translate to superior workforce health and operational performance. This would in turn inspire stronger commitment to create shareholder value and a positive customer experience.

Thus, Mr Kuek invested much time and effort in engaging ground staff, understanding their concerns, and building trust.  For instance, one of the first things he did upon joining SMRT was to send an email to all staff asking ‘What are you thinking?”. He was pleasantly surprised to see hundreds of employees coming forward with their thoughts and ideas to make the company better. In addition, various initiatives were put in place to enhance engagement and strengthen open communication. He is heartened that employees appreciate these efforts, as reflected in SMRT’s sustainable engagement score of 86% in the organisational climate survey conducted by Towers Watson. This places the company on par with global best-in-class standards.

 

When asked about how he reconciles SMRT’s role in providing an essential public service while being a publicly listed company whose profit margins are answerable to the shareholders –

Mr Kuek frankly acknowledged that it is not an easy task to provide a public service while remaining answerable to shareholders – but it is not impossible. He shared that SMRT comprises not just Trains and Buses, but also a commercial team which does an excellent job of managing the retail and advertising businesses.

He further revealed that that most of his energies are devoted to improving rail reliability instead of the commercial business because of the urgent need to renew and upgrade the North-South and East-West Lines, Singapore’s oldest, longest and most heavily utilised MRT lines. Much work is being done to reconstruct the biggest arterial lines while keeping the trains running during the day – akin to conducting surgery on a patient who is awake and complaining about the pain.

Despite recent high-profile train breakdowns in the past year, Mr Kuek shared that rail reliability has improved. SMRT’s mean distance travelled between delays of more than 5 minutes has improved around threefold, and the team is striving to bring down the frequency of breakdowns lasting more than 30 minutes. He concedes that SMRT has some way to go before catching up with the best metro in the world. Together with the rest of SMRT, he takes it as a personal and organisational challenge to improve rail reliability standards to be the best in the world.
