A commuter train in Rio de Janeiro left the tracks and hit a pole supporting power lines early Wednesday, causing no injuries but sowing widespread chaos across the overtaxed public transportation system of Brazil's Olympic city. According to AP, officials said that some cars derailed at low speed as the train was approaching a station in the northern Sao Cristovao neighborhood. Live television images showed little to no damage to the train, but iron poles were bent and power lines that feed energy to the train system were downed. Television stations also carried images of the transit woes that followed the 5 a.m. accident, as tens of thousands of train commuters struggled to find alternative routes to work. Broadcasts showed seas of people packed onto narrow train platforms and forming long lines at bus terminals.
