The Washington Post reports that service between Prince George's Plaza and West Hyattsville was interrupted yesterday after a surge suppressor and cable near West Hyattsville started smoking. One rider described the incident as terrifying, saying that she could see sparks and electrical explosions in the tunnel. Before Metro officials suspended Green Line service between those stations (for a second time) yesterday, some riders said that smoke entered their train. This incident does not seem to have anything to do with yesterday's snow, which prompted a few delays on the Orange Line; in any case, WMATA indicates that service throughout Metrorail is now back to normal. As it happens, DCist found a photo of yesterday's pyrotechnical ordeal on the Green Line tunnel -- very scary stuff. more ›
