There are many cases where optical fibers were also cut because they did not know he difference

This is about communication/signalling cable, not power cable.

Anyway, I forgot about the power line of the electric train ETS. I guess it is like power grid line, very high voltage that cable thieves do not dare to cut. The ETS is using 25kVac. Those using the DC voltage is only in Klang valley which is rail powered. Long power line has to be AC to reduce power loss.

It is far in remote area unless KTMB has post every 20km perhaps

Google map looks like 1mm away lah of course WhenI said remote, it does not necessarily means in the middle of the jungle. Remote from KTMB.

Nowadays, they cut in broad daylight also nobody bother because people think they are contractor doing some work. You think KTMB got people stationed in every town or kampung along the railway?

People will usually slow down or even stop to watch accident even minor one, but not to help. They should apply to work as ambulance driver
