Investigators look at 'anomalies' in track circuit

06-24-2009 • AP

[sabotage?] Investigators are looking more closely at a stretch of track near the site of a deadly commuter train crash after finding abnormalities in equipment that senses trains and transmits speed commands. The deadliest accident in Metrorail's 33-year history occurred Monday when a train plowed into another train that was stopped. The moving train was controlled primarily by computer at the time of the crash, but there is evidence the operator tried to slow it down.
