Last month our friend Ayokoi recorded the test run of rolling stock from Sotetsu and Toei on the soon to be opened (this March) Tokyu Shin-Yokohama Line, at Hiyoshi station, where the line begins its underground run. There has been a lot of news about this new line, too much to unpack now, but a posting sometime in the near future will cover run through patterns, schedules, etc.
