US railroad signal information and interpretation

[ATSF3814]

I found this while searching around the web today. It's a really nice guide on the signaling used on US railroads:

This should definitely prove useful for folks having trouble interpreting the signals on US routes in Railworks.

Holy cow that's a lot of info.
Thanks!

While playing the game, I'm always confused by signals (can't remember the meaning), so I just barrel through anything that's not all red.
