- Type 7000 has been remodeled to make the Arakawa Line one-man, and the front window has become a large single window, modeling the appearance of a light and horny overall.
- Since it is equipped with a buegel and is not air-conditioned, it can be reproduced along with the 6000 form in the transition period of one-man [around the first half of the Showa 50s].
- If you arrange bus collections of the same era (toei buses, Kokusai Kogyo buses, etc.) and car collections together, the world of combined orbits of the Showa era will expand.
- The power unit for optional parts will be specified as TM-TR01 for trams.
