The publisher Sonic Powered made a series of six railway simulator games for the 3DS, each featuring a different line: http://www.sonicpowered.co.jp/train/ . They have announced the Eiden edition will be released in Japan for the Switch: https://japanesenintendo.com/2019/09/13/japanese-rail-sim-journey-to-kyoto-coming-to-switch/ . Unlike the 3DS, the Switch does not have region coding, so although the game will be in Japanese, you could play the physical version (as opposed to purchasing digitally) it on a Switch purchased anywhere. Also, they later released English language versions of the Eiden and Okinawa Monorail versions, maybe this will get the same treatment.
