The Los Angeles Metro Rail Blue Line was the first rail line to open and almost all of it did on July 14, 1990. The line's opening was really just a resumption of the former Pacific Electric Interurban Red Car service 29 years after it was suspended in 1961. The majority of the line, except for the street (and brief underground) running at either end is along the same section of track opened by the red cars in 1902. The light rail line is presently operated at capacity with every train using three P850 LRVs. It originally only could handle two car trains but all were lengthened in 2000-2001. Today this interurban light rail line, along an historically vital route is the busiest modern light rail line in the country, Boston's Green Line is the only other line in the country (and it has four branches) to have more riders.
