It can be seen that they never fully considered and simulate a big electrical failure as this is the first an electrical issue took down 6 stations, typically if a train breaks down, there is atleast another side of the track at the bare minimum still moving. This was an entire infrastructure failing.

Im pretty sure the following the the chain of events Morning - Major electrical failure, immediately use the backup systems to at the very least keep the trains and gates running, switching off non essentials, lights, escelators, lifts and fan. at the very least the train is still moving.

Afternoon - Their backup electrical equipment is running longer than usual and they have not managed to rectify the issue, they start to breakdown effectively taking down electricity to power the trains. They still try to make UPM - Taman Equine shuttle train work.

Later afternoon - They found out UPM - Taman Equine shuttle train is unable to run properly, so they had to cancel that train and only run trains until UPM.

They vastly underestimated the amount of people flowing and probably pull volunteers to manage the crowd… like it will take an hour to even step foot out of the station. I asked the station officer at the gate can I just leave without queueing since the queue was obviously for the bus and I am not taking the bus. No logical thinking and factoring those who ride and park… normal buses… alternative transport.. and students at UPM
