An Orange line train derailed on Monday as it headed out of Washington DC to the Court House station in Virginia. The cause of the accident is not yet known, but a previous derailment in January 2007 was blamed on “shoddy maintenance.”
“Metro’s failure to keep up with basic maintenance and refusal to take safety steps recommended for years by internal and external reviews were the likely causes” of that previous derailment, says the Washington Post‘s summary of the federal investigation into that derailment. Considering that Metro is still well behind in its maintenance program, it will not be surprising if this week’s derailment is also due to maintenance shortfalls.
