[N-gauge standard model train] TOMIX Tohoku-Joetsu Shinkansen 200 series K formation 

The 200 series, with its 0 series face, is the representative shinkansen of the Tohoku Joetsu Shinkansen. This is how it looked from around 1997 to 2002.
The 200 series had E, F, G, H, and K formations, such as "Yamabiko," "Aoba," "Nasuno," "Asahi," "Toki," and "Tanigawa," and could be seen all over the JR East Japan area.
When the Yamagata Shinkansen opened in 1992, this K formation was to be coupled with a mini-shinkansen to Fukushima, and was modified to make it easier to use the coupler, which had only been needed for emergencies until then. Therefore, unlike the succeeding Shinkansen, which was designed to be used at all times, a sensor that measures the distance next to the coupler is activated during the coupling process. Also, some formations had coupler covers that were different from the body color, like the F formation.
This formation was originally 8 cars, but was later expanded to 10 cars, and was mainly modified from the F formation. Initially, some trains were coupled with buffet cars, but these were later converted to ordinary cars.
The leading cars were 1500-series cars, which had a single driver's window, unlike the 0-series cars, and later renovation work was carried out on the 1000-series and 1500-series cars.
The maximum speed was 240 km/h, which was not much different from other 200-series cars (excluding some F-series cars). With the opening of the Akita Shinkansen, the number of cars was increased and unified to 10 cars, and 8-car trains are no longer seen.
The trains were coupled with the 400-series and E3-series cars of the Yamagata Shinkansen, and the E3-series cars of the Akita Shinkansen, and at the end of 1999, coupled operation with the Akita Shinkansen E3-series cars ended, and in 2001, they were replaced by the E4-series cars, and in just under 10 years, they lost their coupling partners. However, in the case of the Akita Shinkansen, the maximum speed was limited, which gave the impression that it was a hindrance.
As an aside, when the Akita Shinkansen opened, coupling work was done in Sendai, not Morioka, and between Sendai and Morioka, the Yamabiko was a local train, while the Komachi was an express train, so passengers flocked to the Komachi.
Also, from 1999, cars that had been renovated and extended their life were introduced. The square driver's cab windows, reminiscent of the JNR, were replaced with a single streamlined window, and the paint color was changed to match the E2 series. With the increase in the E2 series and the introduction of the E4 series, it was no longer the mainstay, but in the same year, it was introduced to the Joetsu Shinkansen with the withdrawal of the G series. It was mainly used as the Toki, Tanigawa, Yamabiko, and Nasuno. It was the last 200 series train remaining after the disappearance of the F series, and the original train was in service until 2006, and the renovated train was in service until 2013, and the dumpling nose that evokes the scent of JNR has disappeared from the northern Shinkansen.
