The Washington Metropolitan Area Transit Authority, more commonly known as Metro, recently embarked on a long-term maintenance and improvement plan known as Metro Forward. The six-year program includes $5 billion in improvements to the system - but it also includes an outreach and social media component (Facebook, Twitter). The Washington City Paper recently profiled Metro's new social media team.
So, what exactly happens during those maintenance periods? One of their new products have been documentation - videos, photos, descriptions - of the kind of work that goes on when your train is delayed for scheduled track maintenance.
