Spotted in the Beacon Hill Station:

If the cheetah is the train, what is the gazelle? What is the train chasing? A job? A date? A flight at Sea-Tac? And what does the gazelle stand for in this image? Really, think about it for a minute. And why is the train pictured as a predator in the first place? I thought about this long and hard for two whole days and finally (about an hour ago) concluded this: The train is a cheetah and the gazelle is a car. This must be the ultimate message of this image.
