I'm quite familiar with train traveling.
I would recommend timetable magazines, JR時刻表 or JTB時刻表.
1.You can check your plan whenever you want
- google maps aren't available in tunnels and mountains.
2.You can check what and when the next stop is.
3.Easy to use even if you can't read kanji because each line is individually numbered.
4.There's Furigana for each station.
the letters are very very small.
Google maps would be useful but sometimes I find it indirect. https://www.amazon.co.jp/JTB時刻表2020年5月号/dp/B086...https://apps.apple.com/jp/app/luno-shou-tie/id9...
