東武90000系まさかの大量増備！まさかの30000系の再転用先についても考えてみた。

#TobuRailway The maroon stripes might be disappearing from the Ikebukuro exit of the Tojo Line!? I thought it would just be for the replacement of the 9000 series, but it looks like they'll become a huge force... *This is just my personal, limited-knowledge guess, so please forgive me if I'm wrong. This channel posts videos about trains (mainly Tobu Railway) and train games! Please subscribe. I also accept video requests in the comments section. (Please note that they may not be possible due to the uploader's schedule or budget.) I've created a channel that focuses on games and removes most of the train content! Please check it out if you're interested. (That's why I post less frequently here.)    / @ryosugames
