I was on a train traveling towards Tokyo when a massive earthquake hit Japan on March 11. The train came to a quick stop and began shaking. Buildings around the train swayed back and forth for several minutes. Large aftershocks followed for the next hour or so. Finally, Japan Railway workers set up ladders, and passengers were evacuated.
