I would love dovetail to recreates this Japanese train line for TSW because I used to play this route sometimes when I used to play with Microsoft Train Simulator. This route can be the DLC that based on a Japanese rail-line and give the players to simulate running a Japanese train and railroad.
This route has already been proposed here; https://forums.dovetailgames.com/threads/japan-odakyu-line-shinjuku-to-hakone-and-enoshima.13513/ But I'm all for people bringing it up Definitely would love to see DTG develop a Japanese route and this one seems very wanted.
They should also create the Yamanoto loop line in Japan or do the bullet train line from Tokyo to Osaka
