January 11, 2025 November 29, 2024 Tobu Tojo Line 30000 series 31612F + 31412F entered Minami-Kurihashi for inspection. On January 7, 2025, it conducted a test run from Minami-Kurihashi, and on January 9, 2025, it returned to Shinrin-koen via the Chichibu Railway (pulled by an electric locomotive). Meanwhile, on December 17, 2024, Tobu's 10030 series 11451F + 11454F, which arrived at Minami-Kurihashi for inspection at the same time as 4+4=8 cars, will conduct a test run leaving Minami-Kurihashi on January 6, 2025, and 11451F will conduct a test run leaving Minami-Kurihashi on January 9, 2025. They will be reassembled into 4+4=8 cars on January 9, 2025, and in the end, they will be sent to Kita-Kasukabe without being made into a fixed formation. Tobu 20400 series 21436F (last inspection March 2021, expired March 2025), which entered Minami-Kurihashi for inspection on December 25, 2024, conducted a test run from Minami-Kurihashi on January 11, 2025 (today) between Minami-Kurihashi and Shintochigi. In this video, I filmed the test run from Minami-Kurihashi for each train set, as well as the Shinrin Koen out-of-service. *Some parts of this video were filmed by a friend, which I was unable to film due to work, and I have edited and uploaded them with permission. I would like to thank my friend. ◆Tobu 10000 series 8-car operation Combination (2-car fixed, 4-car fixed Usage status) as of January 11, 2025 ◆Number of 8-car operations Weekdays 9 operations
