The 13th Generation Sounyan Train

Set 11004 of the Sotetsu 11000 series EMU, the 13th generation Sounyan Train

I am happy to share this annual topic with you again this year. On March 16, the 13th generation “Sounyan Train” debuted on the Sagami Railway (Sotetsu) lines.

First, let me briefly introduce Sotetsu and the Sounyan Train.

Sotetsu is a major private railway company based in Yokohama, operating a 44.4-kilometer network in Kanagawa Prefecture. Its lines are double-tracked, electrified at 1,500 V DC, and use a track gauge of 1,067 mm. Since 2019, Sotetsu trains have run through onto JR East lines, and since 2023, onto Tokyu lines as well.

The Sounyan Train is a special train set decorated with Sotetsu’s mascot character, Sounyan. It first appeared in 2014, and its design, both exterior and interior, has been updated every year.

According to the company’s website, Sounyan is a new species of cat who works in public relations as an official employee of Sotetsu. His mission is to help more people learn about the company. To do this, he often appears at events and interacts with visitors. He also writes his own blog and even works as part of a train crew. In the photo above, you can see Sounyan sitting in the driver’s cab, doing his job.

Joking aside, the 13th generation Sounyan Train is assigned to Set 11004 of the 11000 series EMU. The 11000 series entered service in 2009 to replace the aging 5000 and 7000 series. A total of five sets (50 cars) were built by Tokyu Sharyo and JR East’s Niitsu factory. To reduce manufacturing costs, the series shares common technical specifications with JR East’s E233 series.

Finally, let’s take a look at the interior of the 13th generation Sounyan Train (see the photo below). In this design, Sounyan is shown enjoying mamemaki (a bean-throwing ceremony) with his friends, a rabbit and a squirrel. Mamemaki is a traditional event in which people throw roasted soybeans to drive away evil spirits and invite good fortune, shouting, “Demons out, fortune in!”

Sounyan, keep up the good work!

2026 Rose Season on the Arakawa Line

Toei 8500 series Unit 8502 near Otsuka-ekimae Stop

It is rose season in Tokyo now, and we can see beautiful blossoms in many places. This year, I visited the Toei (Bureau of Transportation, Tokyo Metropolitan Government) Arakawa Line and enjoyed the roses along the tracks. As a rail fan who loves flowers, it was a perfect place for me.

First, let me briefly introduce the Arakawa Line and its rose history.

Tokyo once had a tram network of 181 km, but most routes were closed because of heavy traffic. The Arakawa Line is a precious survivor, since most of it was built on an exclusive track. It runs between Waseda and Minowabashi, with a total length of 12.2 km. The entire route is double-track. The track gauge is 1,372 mm, and the electric system is 600 V DC.

The Arakawa Line is also known for its roses. Rose planting began in 1985 by Arakawa Ward. Later, Toshima Ward and local volunteers joined, and they have continued planting and taking care of many kinds of roses along the tracks.

Now, let’s stop and smell the roses! Please look at the photo above.

I took it near Otsuka-ekimae Stop. Roses are planted in the narrow space between the tracks and the road, using the fence as support. The deep red roses were in full bloom. When the tramcar slowly passed by, a gentle breeze carried their sweet fragrance. It was wonderful.

Next, please check out the photo below. I took it at Minowabashi Stop, which is a must-visit spot. This year, I photographed a different flower bed from the one I saw eleven years ago. There are so many flowers that the tramcar looks a bit modest. Maybe that is too much to say, since this is a railway blog.

By the way, the tramcar in both photos is Unit 8502 of the 8500 series. It is a mid-sized 13-meter tramcar equipped with Toei’s first VFD traction system and two 60 kW induction motors.

The 8500 series began service in 1990, but production stopped after only five cars because of financial issues in the Tokyo Metropolitan Government.

Finally, I have some news. The first unit of the 8500 series, Unit 8501, was recently refurbished. I am running out of space here, so I will write about it in a future post. Please look forward to it!

Reunion with VSE

DeHa 50001 of the Odakyu Romancecar “VSE” at the Romancecar Museum

Do you remember my post about the Romancecar VSE last year? Today, I’d like to share a touching reunion I had with it afterward.

First, let me briefly review what the Romancecar VSE is.

In the Tokyo metropolitan area, several railway companies compete with luxurious express trains as their flagships. One of the most venerable and popular among them is Odakyu Electric Railway’s Romancecar, which runs from central Tokyo to the western suburbs. Odakyu has continued developing new Romancecar models one after another since the 1950s.

Among them, the Romancecar VSE (Vault Super Express) entered service in 2005. Its official designation is the 50000 series EMU. Each VSE set consisted of 10 articulated cars, and only two sets were ever built, both by Nippon Sharyo.

After 18 years in service, the VSE was retired in 2023. What happened to it afterward remained a mystery for a while, although I did spot it in the Kitami and Sagami-Ono railyards, as I posted last December.

Any updates after that?

Thank you for waiting. Please take a look at the photo above. One of the VSE’s front cars, DeHa 50001, has been on display at the Romancecar Museum near Ebina Station since March 19 of this year. Needless to say, I rushed to the museum and enjoyed a heartfelt reunion.

What I especially enjoyed was getting a close look at the VSE’s articulated bogie attached to the end of DeHa 50001 (see the photo below). This ND-735 bogie was also manufactured by Nippon Sharyo. I was able to observe the pneumatic springs positioned above the cylindrical pillars from very close range. To place the body support point close to the vehicle’s center of gravity, the pneumatic suspension sits about one meter higher than that of ordinary bogies.

Although it’s truly sad to see the VSE retired, I’m grateful for the opportunity to learn so much from the exhibit. Thank you, Romancecar VSE, for all your years of hard work. Please enjoy your well-earned rest.

New Gondolas on Mt. Bizan

Bizan Ropeway in Tokushima City

(Photo: Nicolai Okkels)

I recently received something I had been hoping for again from a Danish railfan. During his trip around Shikoku Island in Japan, he took many photos, and today I would like to introduce one of them. I would like to express my sincere appreciation to Nicolai Okkels, who kindly shared this picture with me.

Please look at the photo above—the new gondolas of the Bizan Ropeway. You can see blue and red box-shaped cabins standing out against the urban scenery. They look gorgeous.

As I wrote before, the Bizan Ropeway is convenient access to the popular sightseeing spot, Mt. Bizan, in Tokushima City on Shikoku Island. It is a single-cable aerial tramway. It connects Awa-odori Kaikan and Sancho stations. The route length is 787 meters, the height difference is 242 meters, and the maximum gradient is 30.23 degrees. The system operates every 15 minutes, and the maximum speed is 4.1 meters per second. It takes about six minutes for a one-way trip.

This aerial tramway opened in 1957, and the current fourth-generation gondolas started operation on March 30 last year. One unique feature of this system is the double gondolas to secure enough transportation capacity. Each gondola can carry up to 14 passengers, so a total of 28 people can ride on each trip.

For your reference, I would also like to share the older, third-generation gondolas. Please look at the photo below. These round-shaped gondolas are the ones I boarded two years ago. The present cabins obviously have larger windows, so the views are even wider. They have really evolved.

By the way, you may wonder why I posted a topic about an aerial tramway on this “railway” blog. To be honest, there is no deep meaning. But if I have to say something, in Japan, the operation of aerial tramways is governed by the “Railway Business Act.” That is a good excuse!

Hakobyun: A Freight-Only Shinkansen I Recently Found

JR East’s freight-only Shinkansen “Hakobyun” at Omiya Station

It might sound a bit sudden, but do you know the train in the photo at the top of this post?

If you are familiar with Japanese trains, maybe it’s easy. The front car has that cute, streamlined shape that almost looks like a smile. So yes, it is JR East’s E3-2000 series Shinkansen.

But still… something feels a little strange, doesn’t it?

There are no stripes on the front, and all the passenger windows are closed.

What kind of train is this?

Actually, this is a freight-only Shinkansen, Set L69 of the E3 series. It used to be a regular passenger train when it was introduced in 2009, but it was refurbished this January. All the seats were removed and the floors were made flat for cargo. The train has seven cars and can carry up to 17.4 tons of freight—about 1,000 boxes.

It started service on March 23, running between Morioka and Tokyo on the Tohoku Shinkansen line. Interestingly, it is coupled behind a normal 10-car E5 series passenger train. Thanks to this, JR East doesn’t have to add extra train slots on the already busy timetable.

The nickname of this freight-only Shinkansen is “Hakobyun.”

It comes from the Japanese words hako (box) and byun (a “whoosh” sound). Since it’s a very fast freight train, I think the name fits perfectly.

So, what does Hakobyun actually carry?

If you look at the photo below, you can see some examples: fresh fish, oysters, squid, sea urchins, and many other seafood items. It is also ideal for urgent items like blood products for transfusion, and for delicate precision machines that should not be shaken.

Hakobyun, thank you for your hard work. I’m cheering for your future success on the Shinkansen tracks!
