RAILROAD SIGNAL SYSTEM EXPLAINED by an ENGINEER. (previously unreleased)

Previously released as a patreon only video. Patreon and djstrains website will no longer be online, and I will not be creating new content in 2024. However, I have found some videos that were previously unreleased publicly, so I am re editing them and making them public. This is not a comprehensive video, but a general understanding of how to read CSX railroad's signals. DO NOT TRESPASS ONTO RAILROAD PROPERTY!
Be sure to watch or revisit the 400 videos I have made in the previous 13 years.
Watch the whole video for personal insight into my decision to stop creating new content.
