Authorities investigate accident caused by damaged train tracks

SARANURI: -- It will take railways officials at least two more days to fix the damage to train tracks in Saraburi’s Kaeng Khoi district.

A team from the State Railways of Thailand said on Sunday that the damaged stretch was over 100 metres long. 

 

Because of the damage, a train derailed at the spot on Saturday, injuring three people. 

 

An investigation is ongoing to determine the cause of the accident. Railway services have not been interrupted as railway officials designated a nearby track to accommodate trains in place of the damaged line.

That is not damage. The track  does not have the correct Cant (Banking) It's  too flat for the curve so the train falls off, it can not balance on a flat curve

There is also what is called a Twist where cant goes from one rail to the opposite rail too quickly causing wheel unload and derailment, something called rate of change has to be observed to stop this happening

I'm no technical-expert, but to my eye there appears (esp the 1st picture) to be a lot more ballast than normal, could it be that they were re-ballasting or otherwise repairing the line, but hadn't imposed an appropriate speed-restriction ?

 

Or has that just been thrown-up/disturbed by the accident as it occurred ?

given those visuals, hard to believe only 3 people were injured unless there were only 3 on the those cars

Maybe they should try playing with some hornby and gravel to see the outcome.

There were only 3 people on the carts.. it was transporting cement.

Dropping ballast with out cleaning it up afterward, there are a number of factors in derailments and this one has at least 3 or 4 probably as speed of train is also a factor

 

So quite a few negligent people required
