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

Set 7123 of the 7000 Series EMU exhibited at Jakarta Kota Station

(Photo: Faris Fadhli)

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.

Arigato, My Memorable Trains in Indonesia

I recently received some news from an Indonesian railfan. My thanks go to Faris Fadhli, who kindly sent me his recent photos.

On November 11th, PT Kereta Commuter Indonesia (KCI) held a farewell event for the 8500 series, 7000 series, and 203 series EMUs at Jakarta Kota Station.

I knew this day would come sooner or later, but it has finally arrived. These EMUs are unforgettable trains for me—both in Indonesia and in Japan. The 8500 series is the former Tokyu 8500 series, the 7000 series is the former Tokyo Metro 7000 series, and the 203 series is the former JR East 203 series. They were transferred from Japan to Indonesia between 2006 and 2011. After nearly 20 years of service in Indonesia, they have now reached their final chapter.

As I have written several times, I was stationed in Jakarta from 2007 to 2011 as an exploration geologist for a petroleum and natural gas company, living away from my family. Even when work was tough, nothing made me happier than spending weekends enjoying the railways with local railfans. These trains truly gave me energy. Thank you. Terima kasih. Arigato!

I also would like to express my gratitude to Indonesian railway employees and railfans. I was moved to see the EMUs beautifully decorated with farewell stickers. On top of that, I was surprised and touched that the above railfan, Faris Fadhli, and his friend Adam held an exhibition inside an 8500 series EMU. Their enthusiasm really impressed me.

From the next post, I will introduce the trains that were exhibited, along with my own memories. To be continued…

Special Wrapped Train on the Blue Line

GREEN×EXPO 2027 wrapped train, Set 3321 of the 3000N series EMU

This is a continuation of my previous post. On my way back home from Seseragi Park, I happened to come across a special wrapped train at Nakamachidai Station on the Blue Line of the Yokohama Municipal Subway.

Please take a look at the photo above. Here it is — the GREEN×EXPO 2027 special wrapped train, Set 3321 of the 3000N series EMU. GREEN×EXPO 2027 is the International Horticultural Exposition to be held in Yokohama City in 2027. The event aims to propose solutions to global environmental challenges and to explore ways to create sustainable future societies. This wrapped train is designed to support and promote this forthcoming major event.

I was captivated by the colorful design of the train. Please also look at the photo below — the interior is just as vibrant. In the center, you can see the EXPO’s mascot character, Tunk Tunk, with its cute pink, heart-shaped face. Along with Keio’s former Sanrio Characters Wrapping Train and Tobu’s Ikebukuro–Kawagoe Art Train, this GREEN×EXPO 2027 train has become one of my favorite wrapped trains in recent years.

For your reference, the Yokohama Municipal Subway 3000N series EMU made its debut in 1999 to enhance transport capacity on the Blue Line. A total of seven sets, comprising 42 cars, were built. The train is equipped with an IGBT variable-frequency drive system. If you have a moment, please take a look at my previous post, where I introduced Set 3321 as the Hamarin Poster Train in 2016.

It was a pleasant surprise to encounter this special train by chance on my way home. Encounters like this always remind me that even an ordinary journey can bring small moments of delight.

Autumn Colors on the Blue Line

Yokohama Municipal Subway 3000R series EMU arriving at Nakamachidai Station

Autumn is deepening in the Tokyo metropolitan area. The leaves on the city’s trees have just started to turn shades of red, yellow, and brown. I recently visited Seseragi Park in Yokohama City and enjoyed a peaceful stroll. The name “Seseragi” means murmuring in Japanese, and as the name suggests, small streams gently flow through the wooded area.

Please take a look at the photo below. Here it is—the former Uchino Family House. This wooden house with a copper-clad roof was built sometime between the 18th and 19th centuries. It’s not a famous tourist attraction, but it has a wonderfully relaxing atmosphere, surrounded by the soft colors of autumn leaves.

Of course, I can’t end this post without mentioning the railway side of things—since this is a railway blog, after all! To reach Seseragi Park, the nearest station is Nakamachidai on the Blue Line of the Yokohama Municipal Subway. The Blue Line was opened in 1972 as the city’s first subway route. Today, it stretches 40.4 kilometers between the Shonandai and Azamino terminals. The track gauge is 1,435 millimeters, and the line is electrified at 750 volts DC using a third-rail system.

The EMU 3000R series (see the photo above) is one of the main train types operating on the line. It was introduced in 2004 and is equipped with an IGBT variable-frequency drive and a pure electric braking system. You can see the Yokohama Transportation Bureau’s mascot, Hamarin, on the front of the train, along with another large round sticker reading “Green × Expo 2027”. I’d like to introduce a special wrapped train to promote this forthcoming event in my next post. To be continued…

Yo5000 Series: A Preserved Caboose Car

Unit Yo14740 of the Yo5000 series caboose preserved in Setagaya Park

Today, I’d like to share a quiet, low-key topic. Do caboose cars still run on railways in your country? In Japan, they are extremely rare. They remained in operation until 1984, but today they have almost completely disappeared.

Take a look at the photo above. Here it is—Unit Yo14740 of the Yo5000 series caboose. It was originally built in the 1950s as part of the Japanese National Railways’ Yo3500 series. In the 1960s, it was modified into the Yo5000 series, featuring a two-stage link-type suspension system designed for smoother, faster operation. After roughly 30 years of service, it was retired around 1984, when caboose cars were largely abolished. Today, Yo14740 is preserved in Setagaya Park, Tokyo.

When I was a child, I often saw cabooses on the Tokaido Line, coupled to the end of freight trains. The job of conductors aboard these cars might have seemed easy—they didn’t have to operate passenger doors or make announcements. In reality, they were kept busy ordering the coupling and uncoupling of each freight car at stations and writing reports while on the move. A potbelly coal stove was installed, but it must still have been cold in winter (see the photo below). It looks like it was an uncomfortable ride.

The Japanese freight system has changed significantly. Before 1984, freight trains often stopped at stations to couple and uncouple cars. Today, freight trains mostly run directly between terminals, improving efficiency.

Yo14740—thank you for your decades of service. Now you rest, preserved as a silent witness to Japan’s railway history.

Revival-colored Train: The Beginning of the End？

Revival-colored train, Set 7728 of the Keio 7000 series EMU

On October 28, Keio Electric Railway brought back one set of its 7000 series EMU in the original color scheme. I’d like to share this topic and look into it a bit deeper today.

Please take a look at the photo above. Here it is—the revival-colored train, Set 7728 of the Keio 7000 series. The paint has been changed from the familiar double red-and-blue stripes to a single dark red stripe. In addition, the car number plates and company logo have been restored to their original designs.

For your information, the 7000 series debuted in 1984 to increase transport capacity on the Keio Line. A total of 190 cars were built. The trains were originally equipped with a field chopper control system, which was later replaced by a variable frequency drive with induction motors as part of a modernization program.

Why did Keio decide to bring back the original colors now? According to the company, “many passengers expect the 7000 series to return to its original color scheme.” That’s probably true—but I can’t help feeling there may be a deeper meaning behind this decision.

Let’s take a look at similar cases by other railway companies. Odakyu revived the original colors of its LSE Romancecar in 2012; six years later, it was retired. Keikyu also repainted its 800 series in the classic livery in 2016; three years later, it too was withdrawn from service. These examples suggest that a revival color train might sometimes mark the beginning of the end.

I sincerely hope the 7000 series will continue to run on the Keio Line for many more years.

The 60th Anniversary of Hakone Soba

60th anniversary special menu item of Hakone Soba Restaurant: “Mocoron Soba”

Do railway companies in your country diversify their businesses? In Japan, they certainly do. For instance, many railway companies operate their own department stores along their lines. Another example is the real estate business. The residents living in their housing developments are expected to take the company’s trains to go shopping, commute, and attend school.

This diversification also extends to smaller ventures. Take a look at the photo above — it shows a bowl of Japanese noodles from Hakone Soba, a modest restaurant located inside Shimokitazawa Station on the Odakyu Line. Operated by Odakyu Restaurant System Co., Ltd., a subsidiary of the Odakyu Group, Hakone Soba has grown to more than 40 locations along the line. I love this style of noodles — they’re served quickly, reasonably priced, and, of course, delicious. It’s the perfect stop when I’m in a hurry.

In August this year, Odakyu celebrated the 60th anniversary of Hakone Soba. To mark the occasion, a special menu item was introduced. Look again at the top photo — you’ll notice a semicircular fish cake sitting on the noodles. What’s that? It’s Mocoron!

Mocoron, as you may know, is Odakyu’s cheerful blue rabbit mascot. I was pleasantly surprised to find Mocoron appearing as a topping in this commemorative dish. It was as tasty as it was charming.

And there’s more. The Odakyu Romancecar is also joining the celebration. I spotted a commemorative sticker on the side of Set 30255 of the EMU 30000 series. The entire Odakyu Group seems to be celebrating the 60th anniversary of Hakone Soba together — truly, an “all hands on deck” moment for this beloved brand.

It Was Gone Before I Knew It

“The 100th Anniversary of Kiyose Station” commemorative train (December 2024)

This may sound sudden, but just imagine: there was someone you were fond of — someone who caught your attention. One day, they suddenly moved away and never came back. You feel a quiet loneliness without them. Have you ever experienced something like that?

So, what am I trying to say?

On October 2nd, Seibu Railway announced that the regular services of the 2000 series EMUs would be withdrawn from the Ikebukuro, Toshima, Sayama, and Chichibu lines by October 15th.

Let’s take a quick look back at the Seibu 2000 series. The 2000 series EMU debuted in 1977 to strengthen Seibu Railway’s transportation capacity. There were two types: the original 2000 series, which were retired in June this year, and the newer 2000N series. This time, it’s the 2000N series that have left the Ikebukuro and related lines.

As you know, the Ikebukuro Line is Seibu Railway’s main artery. The 2000N series, with their bright yellow bodies, were the quintessential Seibu trains. This combination was inseparable — and yet, it has come to an abrupt end. I can’t help but feel a bit lonely without them.

Pulling myself together — please take a look at my photos.

This is the special poster train featuring Set 2071 of the 2000N series EMU, celebrating the 100th anniversary of Kiyose Station on the Ikebukuro Line. The commemorative train ran from June 2024 to March 2025. In the end, it turned out to be my last chance to photograph the 2000N series on the Ikebukuro Line.

Thank you, the 2000N series on the Ikebukuro Line. Let’s meet again on the Shinjuku Line.
