Thanks for stopping by Tokyo Railway Labyrinth! Hard to believe this is already the 2000th post. I’m truly grateful for all the international rail fans who keep visiting this blog.
To celebrate this “2000” milestone, I’m revisiting trains with “2000” in their name. You might remember the post I wrote back in January about Keio’s new Series 2000 EMU. Today, I’m diving a bit deeper into the technical side—so let’s jump right in.
The Series 2000 is a commuter EMU built for 1,500 V DC and runs on 1,372 mm gauge track. Each trainset is 200 meters long with a 5M5T formation—five motor cars and five trailers. The stainless-steel bodies feature a repeating circular motif, giving the train a clean, modern look. Its traction system uses a full-SiC VFD paired with 150 kW induction motors. Keio plans to introduce four sets in total by March 2027.
One interesting technical highlight is its deceleration-feedback braking system. Even if Car 1 experiences wheel slip, Cars 2 and 3 automatically boost their braking force to maintain a safe stopping distance. The system adapts well to rain, snow, and different loading conditions, making it reliable in everyday operations.
Okay—enough heavy talk. Let’s switch gears and take a look at the photo above.
You’ll notice a special commemorative plate on the front of the train, celebrating the Series 2000’s introduction. It was displayed for only one month after its debut on January 31, so I’m glad I managed to catch it early.
Now, check out the photo below. The interior is bright and colorful—regular seats, priority seats, and even the flooring all have their own distinct tones. I can’t wait to ride this train myself again!
