Very well detail and understanding of the subways and equipment

[@docphillips5153]

I kind of thought when I saw them it was for additional grounding or return signals. Thanks for the info.

Now let's all have a MORE DETAILED DESCRIPTION in a later video!!

[@NYRTIG]

Certainly, we'll revisit this topic in a longer video, delving into impedance characteristics along with single and two rail track circuits when we discuss signals. We must also be cautious about what we disclose, balancing between sharing insightful information and respecting confidentiality. This balance has been carefully maintained in this video. More to come.

Didn't know the MTA actually had fourth rails! Does this mean that every extra rail on the tracks is a fourth rail, or is there sometimes these extra rails that aren't fourth rails? Is there a way to distinguish them?

[@NYRTIG]

That's a great question! No, it doesn't. Additionally, there are Guard and Emergency Protection Rails in place to help prevent derailments. This supplemental return setup (4th Rail) is found only in a hand full of locations throughout the system based on certain criteria. One way to identify it is by spotting wayside return cables connected to the track.

@@NYRTIG I see, thanks!
