The National Transportation Safety Board will launch an investigation into Sunday’s early morning collision between two Metrorail trains at the West Falls Church rail yard, as the Washington Post reports this morning. Three Metro employees were injured, and a minimum of $9 million in damage – a total that is likely to rise – occurred as a result of the crash. As we noted at the end of the day yesterday and the Post elaborates, at least some Metrorail operators have been saying that Sunday’s collision could have been caused by a kind of “power surge” that they say sometimes happens when trains are moving slowly in the rail yards.
