Why I went to Kaizuka was not only to photograph Nankai 50000 Series. I also travelled on Mizuma Railway Mizuma Line between Kaizuka Station and Mizuma-kannon Station. On Mizuma Line, 1000 Series (refurbished Tokyu first 7000 Series) is in service. All of Mizuma Line is single-track except Nagose Station, and the train operates every thirty minutes in each direction.
1000 Series has two types of front design; original cabbed carriage and converted from a middle carriage. The train I got on from Kaizuka Station was a latter, 1005F set.
I found a hanging strap with Shibuya 109 advertisement (fourth photograph), which shows the carriage came from Tokyu.
On Mizuma Line, four 2-carriage trains exist, and two sets among them are in service in the daytime. On that day, 1001F and 1005F sets are in service.
Arriving at Mizuma-kannon terminal, I saw the two out-of-service sets staying at the railyard near the station (fifth and sixth photograph).
I started photographing the trains. I did one between Mori Station and Mitsumatsu Station (seventh photograph), the two meeting at Nagose Station (eighth photograph), and 1001F set near Koginosato Station (ninth photograph).
Because I like Tokyu Carriages, I have longed to travel on Mizuma Line. Many of the first 7000 Series moved to other railway companies in the 1980s and 1990s. However, those on Chichibu Railway and Fukushima Kotsu retired. The first 7000 Series is in service on Konan Railway in Aomori Prefecture, Hokuriku Railway in Ishikawa Prefecture, and Mizuma Railway in 2022. The carriages on the three railway companies also can do in a few years because it has passed about 60 years since their manufacturing.
I want to keep watching the first 7000 Series to their retirement because they are not only the first full-stainless-steel-bodied carriages making Tokyu Railways' history but also modernising railways in remote areas.
