Empty Train Terminal.

Trains used to rumble in and out of this once-busy terminal, but now they sit at their stations, quiet giants that can be used to transportation, or as a tool of destruction. When the humans were still thriving, a horrible accident occurred at this very terminal. Someone messed with the controls, and all the trains backtracks and crashed into each other, all ten trains exploded as they came onto each other at full speed, killing all in their cars and killing, maiming, and injuring thousands more still on the platforms. Only a few remained unscathed, but sometimes, late at night, you can watch it all happen over again, the horror that happened here that day.
