The 6000 series of the Tokyo Metropolitan Bureau of Transportation debuted in 1947 as the first post-war manufactured train. Over six years starting in 1952, 290 units were produced, serving as the core vehicles of the time. Similar designs were widely adopted by other cities. While most units retired with the closure of the Toden lines, except for the Arakawa line, some continued service there, with the last unit active mainly in events until 2001.

-The train can be motorized to an N scale train and is compatible with TM-TR01 Motorized Chassis.
