also some CII and CIII trains were seized by the Soviet occupation forces in 1945, which were stationed in the Friedrichsfelde workshop at that time. The trains were transported to Moscow and were used in the Metro until 1966. D and DL type cars After World War II the trains of the Berlin U-Bahn were worn out, making a new series of trains necessary. From 1957 on the new D type trains were delivered (also called Stahldora/Steel Dora). They were made of steel, making them very heavy. In 1965, the DL type was developed, which was constructed from lighter metals (also called Dora). This way, weight was reduced by 26%. Like in earlier types the seats were located along the sides of the train. E type cars, transportation of cars to Moscow In East Berlin, the vehicle situation was poor. Because the C-trains had been transported to Moscow as stated above, there were no Großprofil trains left for the Line E. So, just like in the beginning years of the Großprofil, Kleinprofil vehicles with boards attached to the sides were used. These trains had the designation AI K. 40 trains were being re-deployed to the Line E after the war. These "Blumenbratter" trains were also deployed on Line D on the Workers' Uprising and the Berlin strike in 1953. The actual last day of service was on 16 July 1994. F type cars In West Berlin, the new F type followed the D and DL types. These trains were longer, built from light metal and had a different seating arrangement, with the two double seats at 90 degrees to the sides of the train. A test vehicle was built in 1973; it was scrapped in December 2006. H type cars In the meanwhile, the F type had become quite old-fashioned, and the BVG decided to commission another new type. A train with completely joined compartments was chosen, and the seats along the car walls returned. This type was called H. In 1995 the first prototypes (H95) were delivered to the BVG. In 1998 and 2000 further batches (H97 and H01) were ordered from Adtranz. The interior was mainly painted white and yellow. The cars can only be uncoupled in a depot. These trains are manufactured by Bombardier Transportation. Today, all H type cars ran on almost all lines. I type cars The BVG meanwhile awarded the I trains to Stadler
