Autumn Visit to the Silent Tracks of the Ahina Line

An abandoned track of the former Seibu-Ahina Line

Are there any ruin enthusiasts in your country? In Japan, there are quite a few. They love exploring deserted towns, mines, factories, and things like that. I’m not exactly a ruin enthusiast, but I’m at least fond of abandoned railway tracks. Let me share one of my memorable abandoned tracks with you today. My thanks go to the Chairperson of the KuHa 703 Preservation Society, who kindly told me about this heartfelt ruin.

The Ahina Line was opened in 1925 as a branch line of what is now the Seibu-Shinjuku Line. The route originally functioned to transport gravel from the Iruma River riverbed to large cities for construction. Connecting Minami-Ōtsuka and Ahina, the route length was 3.2 kilometers. The track was single and electrified. After 38 years of operation, the Ahina Line was closed in 1963.

Please take a look at the photo above. This is the former Seibu-Ahina Line. The track has been left untouched for a long time, and in this season it was covered with fallen leaves. It would be impossible to revive it now. I felt sad as a rail fan, but at the same time, the abandoned track looked beautiful and somehow made me feel calm. It was different from other abolished tracks I have visited in urban areas, such as the Sagami Branch Line, parts of the Toyoko Line, and the Yokohama Harbor Line.

Finally, I have to say that ruin enthusiasts must follow rules when visiting abandoned tracks. Many dangerous spots lie in prohibited or private areas. Please be careful.

Tobu 8000 Series: An Endangered Species

Set 8199 of the EMU Tobu 8000 series arriving at Shinrinkoen Station

I have to admit, being a rail fan is a bit of a mixed bag. On one hand, we get super excited about new trains. On the other, it’s really sad to see old ones retire. So, what do we really feel? Honestly… both. Today, I want to talk about the sad part.

On October 16, Tobu Railway announced that Set 8577 of the EMU Tobu 8000 series will retire soon. It’s going to be moved to Zao Ropeway, one of Tobu’s subsidiaries, and apparently it will be used as a waiting room for the ropeway line. I was really shocked when I heard this, especially since Set 8577 was just on display as an active train at the Railway Museum from April to May this year.

The 8000 series first came out in 1963 as Tobu’s commuter train for busy city routes. Over the next 21 years, a total of 712 cars were built by ALNA and others. But even trains can’t escape age. Their numbers have been slowly going down, and scrapping started back in the late 2000s. Now, only 167 cars are still running.

After reading the news, I went to Shinrinkoen Station on the Tobu-Tojo Line to catch a glimpse of the 8000 series. These days, all of them run in 4-car formations. The long 8000 series trains are gone, and they don’t even run into central Tokyo anymore.

The EMU Tobu 8000 series… I didn’t realize there were so few left. You really are an endangered species now.

Class C10: A Super-Rare Working Steam Locomotive

Unit 8 of the Class C10 steam locomotive standing at Shin-Kanaya Station

I recently had a chance to visit the Tokai region with my family for the first time in six years. The Tokai area is relatively warm, allowing visitors to enjoy autumn colors for a long period. Since it was a family trip, I had been refraining from trainspotting. However, when I saw an extremely rare working steam locomotive at Shin-Kanaya Station on the Ōigawa (Ooigawa) Railway, I couldn’t help immersing myself in photographing it.

Please take a look at the top photo. Here it is — Unit 8 of the Class C10 steam locomotive (hereafter C10 8). It is neither preserved nor on display; it is still very much active on the tracks. How beautifully maintained it is!

The Class C10 debuted in 1930 to replace the Japanese Government Railways’ aging locomotives. It is a 2-6-4 tank locomotive (Whyte notation), and a total of 23 units were built. C10 8 was manufactured by Kawasaki Sharyō. The Class C10 looks similar to its younger colleague, the Class C11, but for example, the bottom of the driver’s cab door on the C10 is higher than that of the C11 (see the photo below). More importantly, the C10 has a larger axle load than the C11, so the Class C10 locomotives were mainly operated on trunk lines.

After 31 years of service, C10 8 was retired from the Japanese National Railways (formerly the Japanese Government Railways) in 1961 and was transferred to the Ōigawa Railway in 1997. Today, C10 8 is the only surviving Class C10 steam locomotive. None have been preserved or exhibited in museums or parks.

Mt. Takao: A Mountain Where Tengu Live

Funicular Aoba climbing the Takao Tozan Railway Line

Mt. Takao is a popular sightseeing spot near downtown Tokyo. It takes less than two hours to reach the 599-meter summit from Shinjuku, one of the sub-centers of the city. In this season, visitors can admire beautiful autumn foliage—maples, beeches, ginkgo trees, and more.

But there is more to the highlights of Mt. Takao. This mountain is also known as a sacred place for Shugendō, a form of Japanese mountain asceticism. Practitioners of Shugendō belong to Yakuoin Temple, which was established in 704, and they undergo rigorous training in the mountains. It is said that Tengu, legendary long-nosed creatures, protect these practitioners on Mt. Takao.

If you would like to know what Tengu look like, please take a look at the photo below. Here they are—statues of winged, long-nosed figures standing within the Yakuoin Temple grounds. Don’t you find them a bit mysterious, perhaps even slightly creepy?

To visit Yakuoin Temple, the Takao Tozan Railway is very convenient. As I wrote before, this funicular line was constructed in 1927. Connecting Kiyotaki Station and Takaozan Station, its route length is 1,020 meters with a height difference of 271 meters. The track gauge is 1,067 millimeters, and trains operate every 15 minutes. The ride from Kiyotaki to Takaozan takes about six minutes.

Although the line is short, it is famous as the steepest railway in Japan, with a maximum gradient of 31 degrees 18 minutes. In the photo below, you can see the funicular Aoba climbing the track, backed by the early autumn colors.

I truly enjoyed both the beautiful autumn scenery and the mysterious Tengu legends on Mt. Takao.

Arigato, the 7000 Series EMU in Indonesia

This post is a continuation of my previous one. Once again, my thanks go to Faris Fadhli, who kindly shared his recent photos with me.

Please take a look at the photo above. One of the trains exhibited at the farewell event for former Japanese rolling stock in Jakarta was Set 7123 of the 7000 series EMU. Its red, white, and dark blue stripes are visually striking. You can also see a special round headmark on the front reading “ARIGATO, TERIMA KASIH, 2010–2025”—beautiful!

Set 7123 was built in 1983 by Kawasaki Heavy Industries. The 7000 series is an EMU designed for 1,500 V DC and a 1,067-millimeter gauge. In Japan, it was operated as a 10-car train with six motorcars (6M4T). The electric control system was an armature chopper combined with regenerative braking. Air conditioners were not equipped at first, but were later installed in 1988.

After nearly 27 years of service on the Tokyo Metro Yurakucho Line, Set 7123 was transferred to Indonesia in 2010 along with its comrades—Sets 7117, 7121, and 7122. In Indonesia, the 7000 series began service as 8-car trains with four motorcars (4M4T). As of 2011, the 7000 series including Set 7123 carried red, yellow, and white stripes (see the photo below). It was very eye-catching. I also remember that one women-only car was provided on this series. Trains in Jakarta during rush hours were just as crowded as those in Tokyo.

Set 7123 and the 7000 series EMUs… thank you, terima kasih, and arigato. I will never forget you all.
