Yikes. I've been on that train later in the day, but it never occurred to me that it could derail and go up the escalator.
Whenever I'm in Chicago and hear those trains, I'm amazed it doesn't happen more frequently. Some of those trestles where the train is above ground look like they've been there for a 100 years and never updated. With all that clanking and squealing of the wheels, it's scary to be underneath them when they pass above you.
There is danger from all men. The only maxim of a free government ought to be to trust no man living with power to endanger the public liberty.
Public virtue cannot exist in a nation without private, and public virtue is the only foundation of republics. There must be a positive passion for the public good, the public interest, honour, power and glory, established in the minds of the people, or there can be no republican government, nor any real liberty: and this public passion must be superior to all private passions. John Adams
