This happened a few days ago and is apparently a "flaw" in the design. There's a spot that too narrow for two of the trains to pass each other. I put the word flaw in quotes because evidently, this was known and done anyway to meet the demands of the mall developers.
So, I mean, what's wrong with designing an inevitable crash point anyway? All it takes is good timing to avoid and public transportation is famous for it's reliable schedules, right? It's not like trains are ever late or anything... Maybe we can eventually make language a complete impediment to understanding. -Hobbes
...and having read your links, I just don't believe this...
...this is so CRAZY it could only happen under capitalism...
