King Street seems like it's in bad shape, Braddock seems fine (those are the two that I regularly take). Most people around where I live seem to prefer metro express buses to the train. I think Old Town businesses will scream bloody murder since so many hotels are centered around the metro and then the free trolley pretty effectively delivers tourists to over priced shops
The two stations are almost interchangeable for Old Town folks - close one at a time, why can't they do that?
