The most numerous and well-known examples are the Yamagata Shinkansen’s “Tsubasa” and the Akita Shinkansen’s “Komachi”. The “Tsubasa” is combined with the “Yamabiko” between Tokyo and Fukushima, so it is referred to as the “Yamabiko-Tsubasa” south of Fukushima. The “KOMACHI” is combined with the “HAYABUSA” between Tokyo and Morioka, so it is referred to as the “HAYABUSA/KOMACHI” south of Morioka. On the other hand, the Western Yokozuna (?) On the other hand, the Western Yokozuna (?) is the Kanku-Kishu-ji Rapid. The “Kanku-Kishu-ji Rapid” heading for Kansai International Airport and the “Kishu-ji Rapid” heading for Wakayama are combined in the section from Kyobashi or Tennoji on the Osaka Loop Line, going around via Osaka Station, and from Tennoji to Hineno where it enters the Hanwa Line. They will be detached at Hineno. In addition, the “Sunrise Seto” and “Sunrise Izumo” trains are combined between Tokyo and Okayama, and the “Midori” and “Huis Ten Bosch” trains are combined between Hakata and Hayaki. In the case of private railways, Odakyu used to be famous for its express trains between Shinjuku and Odawara/Hakone-Yumoto and between Shinjuku and Katase-Enoshima, which used to run together between Shinjuku and Sagami-Ono. However, they are now operated separately, and only some limited express trains are combined.
The scary thing about a concurrent train is the mis-ride. If one train is actually made up of two trains that are concurrently running, the problem is which train to get on. For example, if you get off at Osaka Station on the Loop Line platform to go to Kansai Airport, there is a “Kanku-Kishuji-Kaisoku” train, so you jump on it. If the hako you get on is that of the Kanku-Kishu-ji Rapid, it is fine, but if you get on the wrong hako of the Kishu-ji Rapid, it will take you to Wakayama. Fortunately, I have never taken the wrong train, but I have had a close call. When I left Copenhagen Airport in Denmark for Krisjanstad in Sweden, I boarded a combination train, four of the eight cars of which were bound for Hesleholm and the other four for Karlskrona via Krisjanstad. If you look closely, you can see that the departure sign at the station has information on where to board the train, and there is also a display above the train entrance that shows the destination, but this kind of information is only useful if you know that such information is there. I thought I had boarded a train bound for Karlskrona by looking at the display, but I was so worried that I asked someone who was close by (a very rare case for me). Fortunately, I did not get on the wrong train and arrived at Krishanstad.
Even if the cars are mated, they may not be able to go back and forth between each other. It would be nice if the cars that are mated could go back and forth between each other with a throughway connected, but this is not always the case. However, this is not always the case. Connecting through routes means more work to be done when splitting or merging trains. Therefore, some trains are running without connecting through tracks, such as the “Kanku-Kishu-ji Rapid”. In addition, since the Shinkansen bullet train has a streamlined leading section and the driver’s cab and equipment compartment are filled, it is naturally impossible to go back and forth inside the train even if it is combined. The train has to run on the platform at each stop along the way. Therefore, when boarding a train in a section where such trains are operating together, it is essential to make sure that the boarding position is correct. Of course, the train operators are making various efforts, but there is nothing that can be done if you do not see the signs, and there is no guarantee that you will not make a mistake if you rush to get on the train and get on the wrong one. In the end, the only thing that can be done is to “go up to the platform with plenty of time to spare and pay attention to the information posted and announced on the platform.
