    Thank you for these videos. Recently took the train operator test in june and scored a 90 so just waiting for my call back. These videos are amazing for me to get a head start ahead of school car training

      Congrats, we're sure you'll enjoy joining RTO. Happy the content is getting you in that school car mind state. As stated, this series is a scaled-back school car for everyone. So, with that said, there is a bit that we can't cover. We can give you the philosophies and the whats but not the methods and hows. So you're in for a ride, no pun indented :) We have a few more videos coming your way, and thanks for following best of luck with everything!

    3:00 A variant of the two-shot grade time features a yellow-over-D indication. An example of this can be seen on D4 track outside of the Briarwood station. The D indication means that the next signal is a home signal and the switch beyond it is set for a Diverging route (i.e. once the timer for that home signal runs out, it will show not-red over yellow).

    • @captainkeyboard1007
      @captainkeyboard1007 14 днів тому

      On the B-Division, both B-1 and B-2, the letter represents the line or route code, and the number is the track and signal number. For instance, D4 represents the West End Line, formerly of the BMT, which is now of the B-1 Division; D4 of the B-2 Division, formerly the IND, represents the Queens Boulevard and Hillside Avenue line. On the A-Division (formerly the IRT), the southbound local or main track is called Track 1; the southbound express track is Track 2; the northbound express track is Track 3, and the northbound local track is Track 4. The numbers on the signals on the northbound express track end with 1; the southbound express track has signal numbers that end with the number 2; the signals on the northbound local track end with the number 3, and the signal numbers on the southbound local line ends with the number 4.

      Indeed, we tried to keep it broad for easier comprehension and privacy we had to redact around 5 minutes of the video, including Key-by timers, due to concerns it was threading the needle with this one. We'll follow up with a signaling and sign how to read video we'll cover illuminated S and D signals along with Station time indications and more.

      Sorry to correct you but the term “motorman” doesn’t apply because you have women who operate trains. You can’t call them motorwoman. 31 years and counting up front.

    Is there a video showing if a train is stuck leaving the station, the train behind it can pull up right behind it and let its passengers out through the first door of the train. I seen this a few times before.

    • @Subways_io
      @Subways_io  13 днів тому +1

      Great point, yes, we can speak on it a bit. In that scenario, the Key-by function, as covered in the video, can be used. There's also another direct procedure to get around the Automatic Tripper, which we are restricted from covering. But either method, under the directive of OCC or supervision, can override and get two trains in the same block. As far as the door, the process is known as Keying a door a single door panel can be opened manually at the crew door switch. Located at L1/R1 or L6/R1 (A division) L8/R1 (B division). Hope that helps visually this is as close as we can get.

      Indeed, there are a lot of moving parts, but there are different levels to it. This breakdown is simplified, as there is a much deeper layer involving relays and logic that isn’t covered here.
      This video mixes signaling and maintenance-of-way (MOW) concepts with operational translation, so it’s completely understandable if it feels a bit overwhelming.

    For clarification, a timer is a measurement of how long it should take a train to travel from the Insulated joint to the signal at the posted speed limit?

    • @Subways_io
      @Subways_io  14 днів тому +2

      Correct with the length of that block as your space to get speed and velocity under control before entering the second block (Red/White), which serves as your posted speed check. This varies a bit with two-shot timers, as trains are traveling a bit faster.

    • @Subways_io
      @Subways_io  10 днів тому +1

      You’re correct in some senses, but let’s not paint it with such a broad brush.
      Keep in mind that there are different types of CBTC setups: CBTC Pure, where traditional signals are removed, and CBTC Overlay, where both CBTC and traditional track blocks exist to accommodate non-CBTC equipment.
      The Canarsie Line between East New York and Rockaway Parkway uses this overlay setup, allowing non-CBTC trains to access the yards in Canarsie and East New York. As a result, Signal 102 principles still apply there.
      CBTC operates with a background system called AWS (Auxiliary Wayside System), which manages signals for both CBTC and non-CBTC-equipped trains. The timer principles mentioned in this video are covered in CBTC by Automatic Train Protection (ATP), which enforces speed limits and train spacing.
      Also, keep in mind that interlockings are still protected by traditional home signals.
      We’re currently working on a full CBTC 101 breakdown, where we’ll cover these systems in detail. It made more sense to first explain the traditional setup and then build into modern CBTC.
      Here’s a CBTC short as well-thanks for the comment!
