injuries from escalator

Microfilm of escalator mishap report by The Straits Times on 14 May 2003

On 13 May 2003, an escalator accident involving 20 over people took place at City Hall MRT station. The escalator had suddenly reversed direction and threw commuters off balance, causing injuries to a few.

“SMRT never publicly revealed the cause. It was officially revealed to us staff as being due to the main drive chain sprocket key shearing off due to galvanic corrosion.” said Jack (not his real name)

Speaking on the case, “That was this asshole’s fault. The bastard implemented the “Keep left on the escalator” despite objections from myself and a few others that this will cause uneven wear resulting in premature equipment failure.”

Jack is the engineer who shared his resignation letter with The Online Citizen (TOC) and the alleged cover-ups by the SMRT management on maintenance issues.

He pointed out this particular incident at Cityhall MRT station to TOC, saying to be a classic example of the issues with SMRT’s maintenance system.

“True enough, the step chain, the mechanism that moves the steps all became elongated on one side. This forced us to overtension one side to ensure that the steps remained straight. This caused severe loading and shear stress on the gear box. End result, the sprocket drive key sheared off, causing the escalator to slip backwards by gravity. The report officially stated corrosion, but it was a cover-up.”

Jack added that increased breakdowns of escalators over the years was a likely resultant of the courtesy campaign to keep left on escalators by SMRT since 2002.

“Overhauls themselves are routine. However, the keep left policy has caused an upsurge in overhauls, including escalators that were just overhauled a few years earlier.”

“That’s because LTA has planned the direction of the escalator direction based upon passenger loading. Remember, in the city area, morning peak most are moving up out of the stations to go to work while in the evening, most are moving down. This plan was approved by Ong Teng Cheong himself after careful study, back when the government was still honest and competent.”

According to an article on Escalator World, “Authoritative policies and signage such as “Stand on the right” do not encourage uniform wear in the chains over the width of the machine, because one chain is subjected to a higher force and more wear than the other.”

Jack said that after this particular incident, all the gearboxes were replaced by new ones with main drive chain sprockets molded in one piece to the drive shaft so that it cannot shear off. However, a few years later, the same thing happened in Orchard station.

“The gears within were all smashed up. Otis, the manufacturer, said they had never seen anything like this before and couldn’t explain what caused it. This does strongly suggest that we staff were right that the City Hall accident was caused by uneven loading causing the key to shear off rather than corrosion since the Orc gearbox was sealed up.” said Jack.

For subways in Hong Kong and Taiwan,  the keep left policy works because the escalator rotates direction to even out the wear and tear and also that the escalators are shorter in length.

Jack’s recommendation to the SMRT, “Abolish it (keep left courtesy campaign) entirely, then carry out thorough inspections to determine scale & extent of damage to the escalators.”

When former President, Ong Teng Cheong proposed the MRT system that consist only the East-West Line and North-South Line, the Then-Finance Minister, and current President, Tony Tan remarked that it was foolish to build the MRT system and objected to the proposal. Therefore in order to have the project going and budget to be approved, the scale of the MRT system was largely reduced, along with the carrying capacity.

Over the years, Singapore’s population has been on a sharp increase, and today, the figure is at a number that is way beyond the population the MRT system was originally designed for.

Jack added that in 2004, the top management of SMRT was very responsible. Only the manager he was under was working under had issues.

In his resignation letter addressed to the then-director of Electro-Mechanical Services and Vice-President of Engineering on 10 September 2004, he wrote,

“I have compiled here a few examples of the problems plaguing EPL, problems that I believe have led to two other long-serving Assistant Engineers, XXX and XXX to resign before me. I have tried hard to change the system from within by raising issues to the EPL management that I think are important and should be looked into urgently, and I have tried to offer concrete suggestions on how to deal with some of these problems, but it appears to me that many of these problems were not, and are not, being dealt with seriously, if at all.

The apparent lack of interest in resolving problems by the EPL management have led to a serious fall in staff morale, with the inevitable drop in staff discipline as well, for verbal and even written letters of warning have been issued widely to many of the men. There also appears to be no consistency to the enforcement of disciplinary standard, for warning letters have been issued to some men for certain incidents, while no disciplinary action has been taken against some other staff for incidents of a similar nature. Orders are often issued verbally, with no follow-up memo, so that it becomes difficult for a staff member to check and clarify on any order he does not quite understand.

Often, when something goes wrong, the men have no way to defend themselves as there is no documentary evidence to back up their assertions.

We have even been ordered to alter reports to suit the EPL management’s view.

As the conditions that the EPL rank and file staff have to work under, it is no surprise that there have been so many resignations as the conditions I have outlined in the preceding few lines make it difficult for us to continue working here.

When asked about the alteration of reports and mismanagement, he said that his manager was, unfortunately, the newly appointed Chief Executive Officer’s blue-eyed boy. So despite his mismanagement on maintenance, she kept promoting him until he reached a position to mess up the entire company.

To show just how strongly he feel on the matter, Jack profess, “if the company decides to press criminal charges against him (the maintenance manager) I’ll identify myself and testify against him.”

Ng Eng Hen: Dust clouds likely caused armoured vehicle collision during Exercise Wallaby

Dust clouds limiting visibility likely contributed to the collision between two Hunter vehicles during Exercise Wallaby, Defence Minister Ng Eng Hen explained in his parliamentary reply. 12 servicemen sustained mild injuries, but safety measures prevented more serious outcomes. A formal investigation is ongoing to ensure further safety improvements.

SINGAPORE: Low visibility caused by dust clouds was identified as the likely cause of the collision between two Hunter armoured fighting vehicles (AFVs) during Exercise Wallaby last month, Defence Minister Ng Eng Hen said in a written parliamentary response on Tuesday (15 October).

The incident, which occurred in Queensland, Australia, on 24 September 2024, resulted in mild injuries to 12 servicemen.

Dr Ng’s statement was in response to a parliamentary question from Mr Dennis Tan, Workers’ Party Member of Parliament for Hougang SMC.

Mr Tan asked for details on the accident, specifically its cause and whether any lessons could be applied to enhance training and operational safety within the Singapore Armed Forces (SAF).

The collision took place during a night-time movement of Hunter AFVs at the Shoalwater Bay Training Area.

The vehicles were returning to base when one rear-ended another. Dr Ng explained that the dust clouds generated by the AFVs’ movement significantly impaired visibility, might likely contributing to the accident.

The 12 affected servicemen sustained mild injuries and were promptly taken to the nearest medical facility.

None of the injuries required hospitalisation, and all 12 servicemen were able to rejoin their units for training the next day.

According to the minister, adherence to safety protocols—such as wearing seat belts and protective gear—played a crucial role in limiting the injuries to mild ones.

Following the incident, a safety pause was immediately implemented, with all drivers being reminded to maintain proper safety distances, especially when visibility was compromised.

Troops were also reminded to adhere strictly to safety protocols, including the proper use of safety equipment, Dr Ng added.

The safety lessons from the incident were shared not only with the affected units but also with other participating groups in the exercise, as well as units back in Singapore, through dedicated safety briefings.

Mr Tan also asked about the broader implications of the incident. In his response, Dr Ng said that a formal investigation had been launched in accordance with SAF’s safety incident protocol.

The investigation aims to assess the circumstances more thoroughly and identify any further measures that could be taken to enhance safety.

Dr Ng shared that recommendations arising from the investigation will be implemented where necessary.

Exercise Wallaby is SAF’s largest unilateral overseas exercise, and the 2024 edition began on 8 September, running until 3 November.

The exercise involves approximately 6,200 personnel, including 500 operationally ready national servicemen.

The exercise has been conducted at Shoalwater Bay Training Area in Queensland since 1990, and it is a key part of SAF’s overseas training program.

The Hunter AFV, one of the vehicles involved in the collision, is a state-of-the-art platform jointly developed by the Defence Science and Technology Agency, the Singapore Army, and ST Engineering.

It replaced the SAF’s aging fleet of Ultra M113 AFVs in 2019, which had been in service since the 1970s. The Hunter is equipped with advanced features, including a 30mm cannon, a 76mm smoke grenade launcher, and an automatic target detection and

tracking system designed to enhance operational effectiveness. It is also capable of traveling at increased speeds and covering longer distances, making it a versatile asset for the SAF.

Government to “carefully consider” Lee Hsien Yang’s demolition application for 38 Oxley Road

The Singapore Government will “carefully consider” Mr Lee Hsien Yang (LHY)’s application to demolish the house at 38 Oxley Road. LHY announced his intent on Tuesday morning following the recent death of his sister, Dr Lee Wei Ling, reaffirming his commitment to honour his parents’ wish for the house’s demolition.

The Singapore Government has indicated that it will “carefully consider” Mr Lee Hsien Yang’s (LHY) application to demolish the family home at 38 Oxley Road.

LHY, the youngest son of Singapore’s founding Prime Minister, the late Lee Kuan Yew (LKY), announced his intention to apply for the demolition in a Facebook post on 15 October 2024, following the death of his sister, Dr Lee Wei Ling, on 9 October.

The announcement marks a significant development in the ongoing saga over the fate of the historically significant property, which has been at the heart of a family dispute since LKY’s passing in 2015.

In his will, executed in December 2013, LKY expressed his desire for the house to be demolished “immediately after” Dr Lee moved out of the property. Dr Lee, a prominent neurologist, had been the last remaining resident of the house.

LHY reaffirmed his commitment to carrying out his father’s wishes, stating, “After my sister’s passing, I am the only living executor of my father’s estate. It is my duty to carry out his wishes to the fullest extent of the law.”

He added that he would seek to build a small private dwelling on the site, which would be “held within the family in perpetuity”.

LHY also referenced his brother, Senior Minister Lee Hsien Loong’s (LHL) remarks in Parliament in 2015, when he was Prime Minister, stating that upon Dr Lee’s passing, the decision to demolish the house would rest with the “Government of the day.”

In response to media queries regarding LHY’s announcement, a spokesperson for the Ministry of National Development (MND) acknowledged the intended application and emphasised that the Government would “carefully consider issues related to the property in due course”.

The spokesperson also highlighted that any decision would need to balance LKY’s wishes, public interest, and the historical value of the house.

The house at 38 Oxley Road, where key decisions about Singapore’s path to independence were made, has been a focal point of public and political discussion.

The future of the house became contentious in 2017 when LHY and Dr Lee publicly accused their elder brother, LHL, of trying to preserve the house against their father’s wishes for political reasons.

LHL denied the accusations, issuing a Ministerial Statement in Parliament, where he also raised concerns over the preparation of their father’s final will. He clarified that he had recused himself from all decisions regarding the property and affirmed that any government action would be impartial.

In 2018, a “secret” ministerial committee, which was formed in 2016 to study the future of 38 Oxley Road, proposed three options: preserving the property and designating it as a national monument, partially demolishing the house while retaining the historically significant basement dining room, or allowing complete demolition for redevelopment. LHL accepted the committee’s conclusions but stated that no immediate decision was necessary, as Dr Lee was still living in the house.

In a statement conveyed by LHY on behalf of Dr Lee after her passing, she reiterated her strong support for her father’s wish to demolish the house. “My father, Lee Kuan Yew, and my mother, Kwa Geok Choo, had an unwavering and deeply felt wish for their house at 38 Oxley Road to be demolished upon the last parent’s death,” the statement read.

She added, “He had also appealed directly to the people of Singapore. Please honour my father by honouring his wish for his home to be demolished.”

Despite selling the house to LHY at market value in 2015, LHL’s stance regarding the house’s preservation became a public issue, especially after the family disclosed that the Government had raised concerns about reinstating the demolition clause in the 2013 will. The ministerial committee had reviewed the matter, but a final decision was deferred until now.

The fate of 38 Oxley Road remains to be seen, but the Government’s decision will likely have lasting implications for the legacy of the Lee family and the conservation of Singapore’s historical landmarks.
