BaltACDSo the operator had a 'speed control system' failure and it was cut out. Was the next stop a mechanical repair site able to fix the control system failure so that it could be cut back in? If the failure was not repaired why would anyone expect it to be cut back into operation in its failed mode? Do we have the start of a cover up by dumping all responsibility back on the train operator?
Sorry, I can't answer that, I'm just the messenger.
The ETCS locomotive equipment is computer based. Perhaps you remember on of the first question of an IT technician in case of a failure: Have you already rebooted the computer.
I just had such a telefon talk about my not working internet connection. It turned out it was my computer. I got a number of tips what to do. One was to reboot the computer first. I did it and my internet connection worked OK again.
So rebooting a computer system is not a bad idea.
Perhaps that was the idea behind the suggested restart at the next stop.
And Euclid is right, the driver can brake manually. ETCS works like PTC but uses trackside transponders similar to Amtrak's ACSES.Regards, Volker

blue streak 1Have a question that hoped some one would have answer. The tracks on the left appear to be of a lesser class than the 2 on the right. Did the train overturn on the "main " line or was it on the tracks to left. If on left could train have been routed incorrectly to those lesser tracks ?
I don't think it had anything to do with track quality. The train was to stop there. All is narrow gauge (cape gauge).
Here are two interesting news articles: https://ibexnews24.com/2018/10/footage-shows-the-moment-taiwanese-passenger-train-derailing-at-high-speed-leaving-18-dead/
The article contains an ariel view of the accident cite and a note that the driver reported a to low air pressure 20 minutes before the accident.
The Taiwan News article is disturbing: https://www.taiwannews.com.tw/en/news/3558111

EDIT; more pictures of overall scene may clarify ?

From International Railway Journal August 28, 2014:
Quote: Signalling improvements are another major priority for the main lines as a means of boosting capacity. While a little further behind the electrification project, Chou says that TRA intends to upgrade its ETCS Level 1 network, the installation of which was completed in 2007, to ETCS Level 2.
“While we are still improving our Level 1 system, we are also establishing a Level 2 system, but this still has some time to go,” Chou says. “We believe that in around 2020 we will start testing on the southern section of network. At present we are still estimating the capacity improvements that such an upgrade will provide us.”
So it should have been ETCS Level 1. The system is fully implemented, able to monitor and control speed and initiate penalty braking: https://en.wikipedia.org/wiki/European_Train_Control_SystemRegards, Volker
Lord, that's awful! May they rest in peace, including the doubtless severely injured who won't make it...
I see the lead car already rising up in front and turning over to the left with centrifugal force when it comes into frame. Does anyone have quick access to Google Earth coordinates or an overhead view of this trackwork to see if the reported 78mph is in excess of likely tipover speed?
What's the Taiwanese equivalent, if any, of the NTSB?
