It's obvious that the Rohr cars first entered service on Metro opening day, 3/27/1976. I think the Breda 2000 Series cars entered service in early 1984. I saw somewhere on the internet that the first of the of Breda 4000 cars entered services on 12/23/1991. The first of the CAF cars entered service on 8/23/2001. The first of the Alstom cars entered service on 10/6/2006. Does anyone know the exact date the first of the Breda 3000 Series cars entered service and the exact date the last of the 3Ks entered service? What's the exact date (if anyone knows) the last of the 4Ks entered service? What's the exact date (if anyone knows) the CAF cars entered service on the Red Line? I think the 2Ks made their debut on the Yellow Line, the 3Ks made their debut on the Red Line and the 4Ks made their debut on the Yellow or Green Lines. Everyone knows the CAFs and Alstoms made their debut on the Green Line.
