The article wouldn't load for me, but did it say anything about why they don't just require the train to be stopped for the doors to open?

- codeulike 12y agoTrain might stop in places that aren't stations. Also different stations need the doors on different sides to open. Therefore its useful to know exact location of train.
- sthreet 12y agoGPS could still be used for that, but what is wrong with opening the doors in the tunnel not at a station? I would think that would be helpful in the case of emergencies where people need to get off the train between stations. If a driver accidentally pressed the wrong button they might want to check to make sure no one is outside the train when they drive off, but I would think that wouldn't happen to much.
