A warehouse fire next to the Lake St. L (Green/Pink lines) has closed Ashland Ave station and a massive fire in an abandoned 6-story building on Wabash next to CTA South Side line near former Harrison Curve has shut down all Green/Orange line service. Last I heard, CFD was expecting the roof of the 1880's-vintage building to collapse and there was fear the walls may fall outward onto the L structure. This has not been one of CTA's better days.
