I believe I should bring this to your attention. There is a guy (Zephyr Audiobook) who reposts author's works as machine read audiobooks. Your "Reincarnated as a steam train with a system in a post apocalyptic world" is among them. This guy has two channels on youtube and two on a site called odysee.com .
Just so people don’t think it’s dropped or lose interest, my Train novel is currently scheduled to be updated every Wednesday. If I don’t post a chapter on that day during a week I will at least make a post saying why.
