You may have heard that a subway train in Chicago derailed at O’Hare on Monday. What you probably haven’t seen is the video of that event actually happening, and it is every bit as scary as you’d think.

Not only is there the dead man’s switch, there’s also a trip alarm that’s supposed to trigger emergency brakes if a train comes into a station too fast. The arms were set off… but obviously, they didn’t stop the train.

But for now, we can just be than
