I would be surprised to find that much of a difference if there are drivers involved, With the couple of automatic systems I know of, they still have visual signals next to the track, regardless of any warning system on the train.

From the article I posted: "Metro's automated system is built around electronic relays on the trains and buried along the track that allow onboard computers to control speeds and stop trains from getting too close to one another."

I'm not sure if that system is in addition to or in lieu of traditional signaling.
Sounds like in addition to traditional signaling.

These trains are supposed to have all that except that one of these were 'older' models and did not have the data loggers installed. For whatever reason the ABS failed.
Same thing happened here with the waterfall accident. They had been installed but were still been tested and could be switched off, and many had been. (can't be done now!)

I know form some of the drivers and guards who had worked with this set G7(train) that it had a bad reputation. It would apply power despite brake applications and dropping the dead man's handle/foot peddle.
