Today, I've got three train journeys from the YouTube channel Arkibk Train Aki. All of them are from rail lines on Shikoku. Figured it's better to theme them to a specific area so you get something of a sample of what the area is like.
In total, the videos will run you about 5.5 hours.
There are a lot more of these videos on the Arkibk Train Aki channel and we'll definitely be back down the line.
As a reminder, if the rumble of engines is too loud or too distracting, I recommend reducing the volume as low as possible while still allowing the more important sounds to come though. (Typical train track sounds, announcements, etc). If you play some lo-fi music in the background it can help cover up the noise while still letting you feel like you're not watching the video on mute.
