MRT train collision: Scientifically, where is the safest place to sit in a train?

In light of the recent MRT train collision in Singapore (Joo Koon), where at least 23 passengers were injured, it may be of interest to consider scientifically, where is the safest place to sit/stand in a train?

We sincerely hope the 23 injured passengers are fine and will recover quickly.

Summary:

  • Most safe position is middle of the train.
  • If you are standing, face backwards in opposite direction of the train’s motion, with your back leaned against a solid support.

According to this article on Huffington Post, scientifically the safest place is the middle of the train.

On a passenger train, your safest bet just may be to sit in the middle cars, or one car behind the middle. After all, most collisions happen at the front or rear of a train, and the types of issues that cause derailments, such as broken rails or welds, tend to occur near the front of the train, according to findings cited by Live Science.

It is quite common sense actually, most collisions happen at the front or rear; it is highly unlikely that the collision happen in the middle given the configuration of the tracks. Also, the front/back will absorb most of the impact of the collision.

Also, rear facing seats are the most safe (but they are not present in Singapore MRT).

In other words, “it comes down to basic physics,” as Placencia said. “When something happens, most of the time you have a problem when a train has to stop quickly… If I’m in a forward-facing seat, then I’m going to be pushed out of my seat. But if I’m rearward-facing, what happens is, I would be pushed back into my seat.”

So the next best thing is if you are standing, stand leaning against a support (e.g. the panel near the doors or the metal pole) facing in the opposite direction of the train motion. So that if the train brakes suddenly, you are pushed back onto the support instead of falling down.

Train delay: Students given full duration for paper (PSLE English Language and GCE O-level Music Performing)

Fortunately, students affected by the train disruption are given the full duration for their respective papers. It would have been quite a traumatic experience though.

SINGAPORE – No exam candidates were affected by the train delay on the East-West Line on Thursday (Sept 28) morning, said the Singapore Examinations and Assessment Board (SEAB) in response to queries from The Straits Times.

As at 8.30am, no schools have informed SEAB that candidates sitting the PSLE English Language and GCE O-level Music Performing examinations were affected by the disruption, said the exam board.

Earlier in the morning, the Ministry of Education said that students who are affected by the train delay on EWL do not need to submit an excuse letter and will be given the full paper duration.
