Why do I like trains? Because, I like to travel and like the travelling sound of trains. They may be true, but I think that there is one more reason. The answer is the beautiful coloring of the train bodies.
Let's look concretely. Please look at the top photo. Set 48 of the EMU 2000 series is the special-colored train on the Kanazawa Seaside line in Yokohama City. It was introduced onto the line in 2019, when the Seaside line was extended to Kanazawa Hakkei terminal. Different from the other trains on the line, set 48 has blue-colored bodies, on which the seaside wave is designed. The train bodies are solid; meanwhile, the wave design on the bodies has a round shape... well-balanced. In addition, the designs on the front and the side bodies are connected. They totally express sea waves. It's well thought out. Set 48 gracefully runs on the elevated track backed by the marina of Kanazawa-hakkei. It fits the sea of Yokohama City.
Incidentally, Kanazawa Seaside line is a rubber-tired AGT (Automated Guideway Transit) transportation system in the southern part of Yokohama City, Kanagawa Prefecture, about 40 kilometers south of Tokyo. It was opened in 1989 by Yokohama Seaside Line Company. Connecting Shin-Sugita on the JR East Negishi line and Kanazawa-hakkei on the Keikyu main line, its route length is 10.8 kilometers. Its electric system is 750V DC. The ATO (Automatic Train Operation) system is adopted, so, there is no driver and conductor on the train.
