Series 209 that was diverted from the Keihin-Tohoku line to the Boso area. It was remodeled at the time of conversion and was exhibited at the public display of the Tokyo General Rolling Stock Center (photographed by the author)
Among the trains of JR East, there is a train with the nickname "Hashirun desu". The 209 series trains were used on the Keihin-Tohoku Line from the 1990s to the 2000s, and moved to the Boso area around 2018. This vehicle is a vehicle that completely reviewed the design of conventional trains, and the essence of this vehicle has spread to private railway vehicles. There is a situation where private railway vehicles made from are scrapped first. [See photos] Actually, there are quite a few on private railways? "I'm running" and his fellow vehicles
■The train was ridiculed as "Hashirun desu". When the 209 series trains were built, the concept of "half life, half price, and half weight" is well known. In fact, none of them ended up being "half", but it is certain that it was an opportunity to reconsider the way we think about trains. When the 209 series was built, JR East was forced to repay the long-term debt inherited from JNR, while also having to replace the aging rolling stock inherited from JNR. I had to build a new car, but I couldn't afford it.
The "price" of "half the price" is the total cost including the cost of purchasing the vehicle, running costs, and maintenance costs. Lighter trains use less electricity to run, which reduces the burden on the tracks. That's why it's called "half the weight". Also, "half life" is intended to review the life cycle of the vehicle. Consumables such as tires and oil are also replaced in automobiles, but trains also have consumables. Each part attached to a vehicle has a different lifespan, but it was thought that shortening the lifespan of the vehicle itself would save the trouble of repairing it.
The 209 series trains were designed after such careful consideration, but fans regarded them as "disposable trains" with a "half life". At the time the 209 series was released, disposable cameras called "Utsurundesu" were in vogue, so they were given the nickname "Hashirundesu". After the appearance of the 209 series, how did private railways respond? Part of the design adopted for the 209 series also spread to private railways, but it was not until the 2000s that it began to spread in earnest, mainly on private railways in the Kanto region.
