Slippery Metro floors — a topic which usually tends to pop up more during icy winters and humid summer days — has been back in the news this week, after two riders in their 70s slipped and fell onto the tracks at Gallery Place-Chinatown on Monday. (Fortunately, some other riders stepped in and prevented a bad situation from getting worse, pulling the pair to safety.) And while slipping onto the tracks is a rarity, there’s a good chance that even the most frequent Metro riders have taken a fall (or at least have lost their balance) at least once on the system’s platforms. But Metro has a plan in place to help with your footing: new flooring.
