The Subway Above the JR East Line

Yotsuya Station: The “subway” Marunouchi Line (left) and the JR East Line (right)

As I mentioned before, Yotsuya, located in central Tokyo, is a complicated station shared by the JR East Chuo Line and the Tokyo Metro Marunouchi Line. For example, JR East’s Yotsuya Station is situated in a valley, with a railway tunnel located just beside it. On the other hand, although the Tokyo Metro Marunouchi Line is a “subway,” its Yotsuya Station is on an elevated track rather than underground. It’s quite confusing—so how are these two stations positioned relative to each other?

I recently captured a photo that clearly explains the mystery. In the top image, you can see a Tokyo Metro Series 2000 EMU on the left and a JR East Series E231 EMU on the right. Notice how the 2000 series rides above the E231 series—literally placing the “subway” above the JR East Line. This curious structure has a fascinating backstory.

The history begins in 1894, when the Kobu Railway (now JR East) built Yotsuya Station in the bottom of a valley. Over half a century later, in the 1950s, Eidan (now Tokyo Metro) began planning the Marunouchi Line as part of Tokyo’s growing subway network. They faced a major challenge: the line was too deep to tunnel beneath the Chuo Line. The solution was unexpected—the Marunouchi Line would be built as an elevated track directly above the Chuo Line, creating this unusual vertical layout.

Today, Yotsuya Station remains a rare example of Tokyo’s intricate railway history—a place where “subway” really means above rather than below.

To close, here’s one more photo showing the Marunouchi Line track as it emerges from a tunnel and approaches its elevated Yotsuya Station. This is a unique feature in Tokyo—a singularity in a city of wonders.

Original Form of the EMU 7000 Series on the Sunzu Line

Set 1 of the Izu-Hakone Railway 7000 Series at Mishima Terminal

I’ve already uploaded over 1,900 posts on this blog over the past 14 years. I think I’ve introduced almost every existing train in the Tokyo metropolitan area by now. But wait—I realized there’s still one model in its original form that I haven’t shown you yet. Sorry if I sound a bit obsessive, but as a trainspotter, I’m particular about featuring trains I haven’t posted before.

Take a look at the top photo. This is EMU Izu-Hakone Railway 7000 Series Set 1. The 7000 Series was introduced in 1991 as a rapid service train on the Sunzu Line. A total of two sets (six cars) were built by Tokyu Sharyo. Set 1 still retains its original look, with its blue-striped front. You may remember when I introduced Set 2 of the 7000 Series on this blog—it was a very unique train with a gold-colored front. However, please note that Set 2 didn’t keep its original appearance; that was its look after renovation. For reference, the body stripe color also differs between Set 1 (original) and Set 2 (renovated); Set 1’s stripe is lighter than Set 2’s.

Over the past 14 years, I’ve sometimes visited the Sunzu Line, but I never came across Set 1 until this May. I wonder why... but finally, here it is! I came across it at Mishima-hirokoji station (see the photo below). Set 1—I hope we’ll meet more often from now on. I feel relieved that I can finally introduce the original form of the Izu-Hakone Railway 7000 Series EMU.

A Hanging Strap with a Unique Design: Part 2

Mocoron-themed hanging strap in the Odakyu Mocoron Train

I was very surprised when I checked the “Popular Posts of the Last Month” section on this blog. To my surprise, “A Hanging Strap with a Unique Design” was ranked number one. As I mentioned in that post, it was just a “trivial topic” for me, so I was amazed by the result. I always post about what I find interesting, without thinking much about popularity. Even so, it still feels a little strange to me.

Now, this is the second post about the “hanging strap with a unique design". Please take a look at the top photo. I found this strap inside Set 5055 of the EMU 5000 series on the Odakyu Line. It has two small, ear-like protrusions on the top of the ring. Doesn’t it look like someone? … It’s Mocoron!

What is Mocoron?

Mocoron is the mascot character of Odakyu Electric Railway. He (or she) is a blue rabbit who helps promote child-friendly services on the Odakyu Line. Mocoron likes riding trains and is always looking for something fun. Please take a look at the photo below. You can see a stuffed Mocoron sitting in the driver’s cab of Set 5055, which is called the “Mocoron Train”. So cute, isn’t it?

By the way, Odakyu has not officially announced where the Mocoron-themed hanging straps are installed. As far as I know, there is at least one strap in each car of the Mocoron Train. I also found some in a few sets of the EMU 8000 series. In addition to taking photos of trains or observing their bodies, it might be enjoyable to look for Mocoron straps when you ride Odakyu trains. Trainspotting has many small pleasures, doesn’t it?

Nippori after a Long Time

A train view from Shimogoindenbashi (the EMU JR East E7 series)

Do you have a tradition of visiting ancestral graves in your country? In Japan, yes. Many people do it twice a year in spring and autumn honoring their ancestors. From our perspective, it is not so much a religious activity as a custom. Anyway, I recently visited my maternal ancestors’ grave in Yanaka of Tokyo Metropolis. Yanaka is famous for many cemeteries.

After updating my ancestors on how things are going, I enjoyed strolling around. First, I found myself drawn to Shimogoindenbashi (Shimogoinden Bridge) in front of Nippori Station for the first time in ten years. As I posted before, Shimogoindenbashi is well known as a train viewing spot. JR East’s 12 tracks are seen from the bridge. A total of 2,500 trains run under the bridge per day, so, we can enjoy train viewing continuously there. The bridge was crowded with railfans, families and inbound tourists. Please take a look at the top photo. I shot the JR East’s E7 series shinkansen train running under the bridge. I've been taking pictures of the E7 series repeatedly, but there's something special about a long-distance train approaching its goal, Tokyo Terminal. The E7 series… thank you for your hard work.

Another spot I visited was a scenic cemetery on a hill near Nippori Station. I could see an airport access train, EMU AE series “Skyliner” traveling on the elevated track of the Keisei Line (see the photo below). I have passed through this cemetery many times, but this was the first time for viewing trains. Was it a guidance from my ancestors as a token of their appreciation?

Railroad Speeder on the Keisei Line

Keisei's railroad speeder Unit M2591 at Keisei-Makuhari station yard

When I visited the Keisei-Matsudo Line in August, I spotted a rare sight—a railroad speeder, Unit M2591, parked in the Keisei-Makuhari station yard. I got off at the station and was able to observe it from the platform. Please check out the top photo.

Railroad speeder Unit M2591 is a diesel work vehicle built by Matsuyama Jyusharyo Kogyo (MJK). Coupled with rail transport wagons, M2591 carries rails for track maintenance. Its technical specifications are unclear, but it seems capable of hauling over 20 tons of freight. It mainly operates after midnight, once the last train has finished running, so to be honest, I had never seen M2591 in action before. It’s an unsung hero, isn’t it? Its bright yellow body really stood out in the sunlight—beautiful!

Incidentally, did you notice the panda illustration on the side of the speeder? Please take a look at the photo below. This is the mascot character of Keisei Electric Railway, “Keisei Panda.” According to Keisei, he was born as a prince of the House of Panda on Planet Panda. But since he was lazy, his father, King Panda, sent him to Earth for training. Today, he lives in Narita City and works at a zoo as a zookeeper. On the speeder, Keisei Panda is depicted wearing work clothes. You might feel that this version of Keisei Panda looks less cute and even a bit creepy. And that’s right—Keisei intentionally designed their mascot character to have a strong impact rather than just conventional cuteness.
